PRESS RELEASE - Real 3D V 1.3.3 FEATURES

Real 3D is a design and animation program for producing high quality, realistic pictures of three dimensional objects. It provides an impressive set of advanced features including:

Ray Tracing: A ray tracing of Real 3D is strongly based on the physical reality of the real world. Real 3D produces pictures by simulating the laws of physics, and consequently they represent reality with astonishing accuracy.

Speed: Innovative methods and new ray tracing algorithms make Real 3D really fast. When using fastest ray tracing mode, rendering time is typically from 1 to 15 minutes.

Hierarchical Object Oriented Construction: With Real 3D you can create hierarchical objects. This means that objects you create can be made of subobjects, and these subobjects may have their own substructure and so on. This kind of a tree structure is well known in the context of disk operating systems, in which you can create directories inside directories. In Real 3D counterparts of these directories are used to collect objects into logical groups. This kind of approach makes for example object modifications extremely easy, because it is possible to perform operations to logical entities. If you want to copy a DOS directory, you don't have to take care of the files and directories inside it. In the same manner, you can stretch a complex object in Real 3D as easily as one part of it.

True Solid Modeling: Real 3D includes a true solid modeler. Solid model is the most sophisticated way to represent three dimensional objects. This modeling technique requires powerful computing power and therefore it has earlier been used only in environments which are many times faster than Amiga. Now it is possible to Amiga owners to reach all the advantages of solid model thanks to ultimate optimizations carried out when developing Real 3D.

Smoothly Curved Surfaces: In addition to plane surfaces, Real 3D includes several curved surfaces, such as ball, cylinder, cone and hyperboloid. This means that no matter how much you enlarge a ball created by Real 3D, you don't find any edges or corners on its surface. Furthermore, this makes the program much faster. What is most important is that the produced pictures look really good.

Boolean Operations: Solid model allows Boolean operations (AND, AND NOT, EOR, and DIVIDE) between objects. It is possible, for example, to split an object into two pieces and move the pieces apart so that the inner structure of the object is revealed. Operations can also be done so that the properties of the materials of the target objects are changed. By using a brilliant cylinder one can drill a brilliant hole into a matt object. These operations are a powerful way to create and modify objects especially in modeling technical objects.

Properties/Surfaces: A user of Real 3D is not restricted to use some basic surface brilliancies such as matt or shiny. Instead, the light reflection properties can be freely adjusted from absolute matt to totally mirrorlike, precisely to the desired level. Properties/Materials: Due to solid modeling, it is possible to create objects from different materials which have suitable physical properties. Surface brilliancy and transparency of a material can be adjusted without any restrictions. Even light refraction properties are freely adjustable so that it is possible to create optical devices from glass lenses. These devices act precisely as their real counterparts: a magnifying glass in Real 3D world really magnifies!

Texture Mapping: The texture mapping properties of Real 3D are not restricted to a typical chequered pattern. Any IFF picture can be used to paint objects. You can create pictures with your favorite painting program as well as with a video digitizer or a scanner. For example, by digitizing a wood filament pattern, it is easy to create wooden objects looking very realistic. Pictures can be located precisely to desired places, with desired sizes and directions. Real 3D offers as many as five texture mapping methods, including parallel, cylinder, bump, color, ball and spiral projections. All these mapping methods may be used simultaneously!

Bump Mapping: Besides the normal way of Texture mapping there are three other methods of mapping: Bump, Clip and Special mapping. By the use of the bump command you can give a relative height or depth to your textures. The amount of the colour red in your IFF texture defines the relative height or depth in the bump. Then you can use your texture in the same way you use your normal texture. Keep in mind that when using bump mapping the texture will use the original color of the object you applied the texture on. You can also add brilliance and reflection to bumpmaps (water). This function is perfect for creating golf balls or desertsand. By the use of the texture index command you can also create moving water. By the use of the clip command (see materials) you can clip unwanted parts of your textures. For instance you draw a world map in Dpaint on black background., create a texture with it, in the materials menu select clipmapping & no color 0. Now wrap this material on a sphere. Create a new sphere of blue glass and size it a little bit smaller. Lay the first sphere on top of the second and render the scene. You will see a worldmap on a glass sphere. By the use of special mapping you can define the amount of reflection in a IFF texture of green in your bitmap, and the amount of refraction through the amount of blue in your bitmap.

Light Sources: Unlimited number of light sources of desired color and brightness. Light Refraction (speed of light gadget) for REAL optics. Base Light & Background light can be set. The only restriction is amount of memory.

Animation Support: As you can create single pictures, you can create a series of pictures, or animations. Real 3D includes software for representing these animations interactively. Animation representation can be directed by a script language from ascii files, or even from the keyboard. Instead of looping animations you can define infinite ways to represent your pictures. Therefore you can create animations from a small number of pictures by displaying them various ways. New key frame style motion creation and editing, texture animation support.

Rendering Techniques: Real 3D includes several different rendering techniques; a real time wireframe model, a hidden line wireframe model, a high speed one light source ray tracing model, a nonshadow-casting ray tracing model and a perfect ray tracing model. You can select HAM display mode with 4096 colors, a grey scale display mode offering higher resolution, or 16.8 million color rendering (24 bits output) to Targa. Support for other 24Bit boards are in the works. New adjustable image size from smaller than screen to 1024x1024. Special single Photo24 (about 640x500 visible) screen render for SLR camera.

Macro Tool: The macro facility is very useful when you want to execute the same modifying operations to a large number of objects. A macro is a series of modification operations that the user can define to best suit his/her needs. Macros can be stored in memory and then later executed on any object. The operations include; Move, Move To, Stretch, Size, Rotate, Mirror, Explode, etc.

Suggested Requirements: 1MB Ram, 1 floppy drive. (minimum) 3MB Ram, 10MB of hard drive space, 68020/68030

"We're Making Waves with Real 3D"

The BEST Amiga Shareware Comm Program?

By Chris Lawrence

Which is the best Amiga SW Comm Program? Beginners often ask this question, and I, in a miraculous brain-wave, have decided that people starting out online need a good comparison of the "Big Three" Shareware Comm Programs, which are: JR-Comm, by Johnathan Radigan; NComm, by Daniel Bloch (and many others..); and Access!, by Keith Young. (Yes, I know there are others [VLT and HandShake spring to mind], but they are intended for special purposes).

I have broken the competition into a number of cetegories, and I will present a few conclusions at the end, so bear with me..

BEST APPEARANCE: Access!

Access is the only one of the three terminal programs that starts out with a screen that gives you an idea of what you can do with the program. You can do most anything in Access! using the Gadget Bar at the bottom of the screen. This makes it easier to use than JR-Comm and NComm, because you don't have to hunt through menus to find functions (especially when time is money).

BEST SETUP: JR-Comm

JR-Comm is the only program that supplies a program that is devoted to setting up EVERYTHING you need without hunting through menus in the main program. JR-Comm also sports easy-to-use requesters for configuration. Access! and NComm go back to their Comm roots, forcing you to pull down menus and hunt through them for the option YOU want to set..

BEST PHONEBOOK: JR-Comm

JR-Comm sports a phonebook that allows you to choose different palettes for each entry, as well as the standard protocol and modem settings. Access! and NComm also allow you to choose modem and (NComm only) protocol settings.

BEST PROTOCOLS: NComm

NComm's protocol support is second to none - XModem (Checksum, CRC, 1k), True YModem(tm), ZModem (with auto down AND uploads), and Kermit (the only comm program here that supports it). It also supports the XPR (external protocol) standard, so you can use B+ and others if you have the needed XPR library. NComm also supports twelve different ASCII standards, such as ISO (Amiga), US7 (standard ASCII), and IBM, as well as MANY foreign formats.

JR-Comm supports all of the above, except Kermit and XPR and Auto-Uploading (ZModem), but it supports Compuserve B+ and Windowed XModem. IBM and ISO supported for ASCII.

Access! has the weakest support, with only XModem (CRC & Checksum) and WXModem (download only) support. Supports IBM and ISO.

All three support Amiga and/or IBM ANSI Color & Graphics.

BEST SCRIPTING: NComm

NComm has the most powerful scripting language, with over 20 different functions. Access! has a more limited scripting facility, while JR-Comm does not support scripting yet. None of these support ARexx, which is (in my humble opinion) ludicrous. NComm will have ARexx support "by 1992", JR-Comm promises it in "Version 1.1", while Access! (which hasn't seen a new version in 2 1/2 years) doesn't mention ARexx.

BEST CURSOR IMPLEMENTATION: JR-Comm

JR-Comm uses a sprite for its cursor, which makes for a better screen display than is possible using Access! or NComm. NComm in particular is annoying when large blocks of text are being displayed, the cursor doesn't seem to keep up with text (even at 1200 baud), making a "flashing" effect that is extremely distracting.

SKYPIX SUPPORT: JR-Comm

JR-Comm is the only Shareware Comm program that supports Skypix Graphics, used by the Skyline and Atredes BBS systems.

BEST CONFERENCING: JR-Comm

JR-Comm sports a scrolling chat line that doesn't send anything until you press RETURN, so you can edit what you're going to send BEFORE you send it. Also, it doesn't echo characters to the main display (even in half duplex), so you can safely type without things getting "weird" in the main display.

BEST BEGINNING COMM: JR-Comm or Access!

This is really up to personal taste. Access! is easier to get started up, but after a few weeks, you'll really want ZModem support (especially at lower baud rates), so it might be best for you to go to JR-Comm.

BEST INTERMEDIATE COMM: JR-Comm

For its support of A LOT of protocols and PLENTY of options, JR-Comm takes the biscuit.

BEST POWER COMM: NComm

While NComm doesn't have too much more going for it than JR-Comm, the support of Scripts has made in MY choice of terminal program, for the moment. I will say, however, that it sorely needs an ARexx port, and the second JR-Comm supports (at least) ARexx, I will move back to JR-Comm, but I won't go back just if it adds scripts.

AREXX SUPPORT:

If you haven't gathered it by now, I find all of the above SORELY lacking in the ARexx department. ANY programmer whose program has Scripting can implement an ARexx Port in about an hour (this is being liberal) using the freely-distributable RexxHost.Library. That's why the RexxHost library was designed - so people could easily add a Rexx port to their programs. Programmers of the above comms - PLEASE release a Rexx-able version ASAP.

A FEW OTHER BITS & PIECES:

HandShake is NOT for the faint-hearted... It has succeeded in crashing (as in GURUS) while attempting ZModem transfers EVERY time tried.

I haven't used VLT, so I have no idea what it can do... I understand it has an ARexx port though, so it could be good...

AMIGA 500 POWER SUPPLY ADJUSTMENT

My lawyer advises that I gotta say the following things in order to protect myself from some of the ignorant idiots out there. CAUTION: The following instructions involve tasks that might be beyond your skill or experience level. Do not undertake them if you are not capable. Also, if your computer is under warranty, the following instructions will cause it to be voided, since the instructions involve opening both the computer and the Commodore A-500 Power Supply.

FURTHER: I cannot be responsible for anything stupid that you might do while fiddling with the guts of your computer... like busting it... or electrocuting yourself!

The logic circuits of the computer require +5.00 VDC. The floppy drives require +12.00 VDC. Hard drives also require +12.00 VDC.

The 12 volt requirement is very forgiving and seldom causes any problems. The 5 volt requirement for the logic circuits is much more critical.

As you put more and more RAM into the system, the 5 VDC becomes "loaded" which causes a slight voltage drop.

As you add accelerator boards, and flicker fixer boards and other logic devices, the demand for 5 volts grows. This increased demand "loads" the supply, causing a voltage DROP! It is possible for the actual voltage to drop down to 4.50 or less.

Most logic circuits will tolerate a little voltage drop. However, most of them will start to fail if the voltage drops much below +4.85 VDC. When the voltage drops below that level, you can expect the system to "crash".

When the AMIGA system crashes due to low logic voltage, you will get GURU errors like: 0000000B.002569C81

In almost all cases, the GURU error code will consist of seven "0's" followed by a letter or number. Then, to the right of the GURU decimal point, you will get two "0's" followed by "20", "21", "22", "23", "24", "25", "26", "27", etc. These are codes that indicate a logic failure due to insufficient voltage to the Central Processing Unit (CPU).

If you are operating an accelerator board, there is even more load put upon the 5-volt logic voltage.

In the case of the Mega-Midget Racer board, there is a test point on the board identified as J1 that can be used to measure the actual voltage which is reaching the board. The makers of Mega-Midget Racer, CSA (Computer System Associates, Inc), advise me that there must be at least +4.85 volts at test point J1. They would PREFER a full +5.00 volts.

You can check the logic voltage by measuring it with a voltage meter while the computer is turned on and operating. To do this, you'll have to open up the computer and gain access to the working parts.

To open the computer, you'll have to remove all the cables from the back of the computer which will allow you to turn the computer upside down so that you can get to the 6 little screws that hold the cover (top) to the base. To remove these 6 screws you will need a special screw driver with a special tip. It is called a T-10 Torx screw driver. They are available in most "better" hardware stores as well as SEARS. Be sure you get the T-10 Size. Other sizes of Torx screw drivers will NOT work.

Once you have removed the 6 screws, the top of the computer will lift off easily. Next, you will have to un-plug the multicolored cable harness (from the keyboard assembly) that is plugged into the mother board near the center, and through a rectangular hole in... the metal RF shield. Note that the black-colored wire is at the far left-hand end of the connector. Be sure you replace it exactly that way. It is possible to replace the connector wrong!

Once the multi-colored cable harness is un-plugged, carefully bend the little metal tabs that hold the metal RF shield in place, and remove the shield. If you flex the tabs back and forth too much they will break off. Don't worry if they do. It's no big deal. Mine broke off a long time ago. I use a little cloth duct tape to hold the RF shield in place.

Once the RF shield is removed, you can set the computer back in place, and connect all the cables... including the multi-colored cable harness (from the keyboard assembly) that was plugged in through the metal RF shield. The computer can now be booted up and it will operate perfectly normally. Since it is totally opened, it will be possible for you to take voltage readings while it is operating.

Now, be careful. I'm sure that it is possible to screw things up if get stupid enough!

If you plan on doing much repair work on your computer, you should invest in a moderately priced volt meter. Radio Shack has several to choose from. I prefer the digital type that will allow me to read to two decimal points of voltage. Such meters are available for about $40.00. Less expensive meters might not have enough accuracy for use with printed circuits. Also, less expensive meters might tend to produce their own "load" on the circuit that you are tyring to measure, thus producing erroneous readings. I don't like moving-needle type of meters. They tend to be too easily damaged from rough handling. While the more expensive meters are nice, they really aren't necessary for most routine computer hacking.

The AMIGA power connector has several exposed pieces of metal that can be used to take voltage readings. At the top of the connector there is a little V shaped groove that has a little metal insert in it. That is "ground". The 5-volt contact is to the right, and back under a larger metal strip that slants down on an angle. If this description is a little confusing, don't worry. Just place your meter's "ground" probe on the V groove, and start touching the various other pieces of exposed metal that are on the connector with the meter's "positive" probe. Sooner or later, you'll stumble onto the 5-volt contact. Of course, if you're having problems, you won't read a full 5 volts.

The ground probe on the meter might be identified as the "COMMON". But, again, don't worry. Most meters in the $40.00-up price range will automatically protect itself if you happen to reverse the probes, and display to you a "negative" voltage instead of the "positive" voltage that you will be expecting to see.

The standard Commodore power supply for the AMIGA 500 can be adjusted to put out MORE voltage if needed. To make the adjustment, you will now have to open the power supply.

Un-plug it before you start to work on it!

It is held together with four Phillips-head screws. Once the screws are removed, the "top" of the power supply will lift off. Inside there are two printed circuit boards. One is positioned horizontal, and the other, smaller board, is positioned vertical. On the vertical PC board there are two, small, square potentiometers. One is identified as VR2. The VR2 pot controls the 5-volt output level.

Connect you volt meter to the point on the computer's PC board where you want to measure the voltage, and with the computer booted and operating, adjust the VR2 pot with a small screw driver. It will require a VERY tiny screw driver. If you don't have a screw drive that is small enough, you can buy one at Radio Shack.

The idea is to adjust the pot while watching the volt meter. That will allow you to "trim" the pot to just the right amount to produce just the right voltage. Turn the pot counter clockwise to increase the voltage. You'll only need to turn the pot a few degrees of rotation. It is very sensitive.

On my system, I get the following readings when everything is operating correctly.

TEST POINT READING
Power Connector on the Amiga chassis with the computer booted +5.10 VDC
J1 Test Point on the Mega-Midget Racer motherboard +5.00 VDC
The end of the power cable when it is NOT plugged in to the Amiga chassis +5.35 VDC

The J1 Test Point on the Mega-Midget Racer Board must be at least +4.85 VDC according to the manufacturer. They would prefer a full +5.00 VDC.

Once you have the pot trimmed and you're getting the full +5.00 VDC to the AMIGA, you might want to think about rigging a slightly different housing for the Power Supply. As Commodore ships it, it is "air cooled". Which means that it ISN'T cooled at all! I strongly suggest that you either leave the top of the case off permanently, thus providing for much more convection cooling... or mount it in a housing where you can rig a fan to blow on it. The two, large, black aluminum heat-sinks that are inside the housing get very warm. When all of that heat is trapped inside the housing it will tend to shorten the life of the more delicate components.

It should be noted that MICRO R&D's "BIG FOOT" power supply.... CANNOT be easily adjusted to boost it's +5.00 VDC output... and, as it is shipped... it will NOT deliver enough voltage to operate an AMIGA 500 with 7 megs of RAM, a SCSI, and a Mega-Midget Racer board installed. Do NOT be mislead by the "amperage" rating of 15 amps for the +5.00 VDC. The problem is in the gauge and length of wire that is used in the AMIGA power cable. There is simply too much voltage drop, resulting in just barely enough voltage being delivered to the AMIGA mother board to power a bare-bones computer.

My BIG FOOT 150 delivers +4.82 VDC to the AMIGA chassis, and only +4.55 VDC to my Mega-Midget Racer board. In fact, I can't even keep my system booted when I use BIG FOOT!

As of this writing, MICRO R&D is investigating ways to provide for increasing the +5.00 VDC output. They have promised to advise me if they can solve the problem.

In fairness to BIG FOOT, it is, in reality, the power supply used by IBM clones in standard AT-type chassis. BIG FOOT 150 is capable of powering three hard drives and a floppy as well as the main computer. But, when it is used in an AT case, the cable supplying +5.00 VDC logic power is only inches long, and of a larger gauge size. When MICRO R&D reconfigures it for use with the AMIGA, they attach the standard Commodore power cable which is about 4-1/2 feet long and considerable smaller gauge than regular hard drive power cables.

Good luck!

Product GUNBOAT
River Combat

Publisher Accolade
Type Simulation/Arcade

Amiga DOS 2.0 Compatible

When I first heard of this game I was impressed. I thought what a great idea for a game. Of all the simulators out there none are gunboat simulators, at least none that I know of. I picked up the manual and began to read. Everything I read sounded great. You can move to one of several positions: front gun, back gun, pilot, etc.... It talks about the computer sending you on missions to take out targets or cut supply lines among others. It even gives you a choice of different types of weapons to use on your gunboat. Yep, everything the manual says sounded great, now if we could just find the game the manual was written for.

Although some of the features are there; none work well at all. The graphics are poor and terribly slow. The game begins with the worst digitized graphics I have ever seen since A-10 Tank Killer. I think Accolade had the night janitor digitize the pictures for them. I really haven't been able to find anything good about this game. The graphics are sorry, the speed is so slow it is unplayable, and the plot never seems to work. It is hard to figure how a game like this was ever released. As if you haven't figured out what I am saying, keep your 30 bucks, or buy a stack of MAG mousepads, they are more playable that this game is!!!

A Proper Grammar Look at the President's CLI

by Brain Akey

Before Proper Grammar

The presidents cli,

What do we have for this month. We need to get ready for the september computer fair. We are going to discuss the big demos that we are going to have at the fair. We also should be looking forward to the CHristmas party. We are going to try and schedule the party right after the december meeting. We are also going to have a whole new batch of game, music, and utility disks that you don't want to miss. We have Donnie Webb and Ken Winfield to thank for these disks. Presents and money would be fine for there great work. We are going to have a few new programs for doing word processing and some new hot games. One of the programs is Proper Grammer which I will show a sample of by showing the before and after on the president's CLI. So get off your Ski's and come to the meeting.

PRESS RELEASE Chip Ram Excellerator

Most people beleive that their Hi-Res/16 color/Overscan animations play slowly because of the Delta Compression. (The difference between two frames that the computer must calculate.) and by buying the Fastest excellerator card on the market will improve their frame rates. If you allready have a 68030 this is not the case, animation speed is limited to the amount of memory you can move through CHIP RAM, for example, you can play a Overscan 6Bit plane image (HAM/32 Colors) at 30fps, where as a complex overscan 4Bit plane Image (HiRes/16 Colors) plays at 6fps. A good example of this is DCTV. When converting a 24Bit/Overscan animation to run under DCTV, you have a simple choice, make the animation either DCTV 24Bit non-overscan, or DCTV 64000 Colors Overscan.

The Amiga 2000 family (A2000, A2500, Etc.) can move about 1.3MB of Imformation through Chip ram, resulting in frame sizes around 45K for best playback. With the A3000's 32Bit Buss, the speed increases to about 1.7MB/sec. Still your limited to about 50K a frame.

The Hottest new product for the amiga will be shown on October 4th for the first time at the AmiEXPO in California.
