LightWave 3D 3.5 (1994)

  • by

LightWave is my favorite 3D modeling software. I remember when I had it running on a 21-inch Silicon Graphics CRT screen connected to a PC with Matrox graphics card. I was quite interested how fast and usable LightWave was on Amiga computers in mid-90s.

My A1200 is upgraded with 50-MHz Motorola 68030 and it is much faster than original 14-MHz 68020. LightWave 3.5 is very advanced software and even this old version has almost all features that are necessary for easy 3D modeling. That’s why I’m really surprised how fluently it can run on my Amiga computer. If a scene has under 1000 polygons 68030 without mathematical co-processor has still enough computing power for low-poly graphics used in 90s 3D games.

Speed becomes an issue when you want to render a scene. A very simple car needs more than a minute to be rendered in 24-bit mode and 640×480 resolution (without any texture, advanced materials or reflections).

Result? 3D modeling is ok, but you have to be very patient even for static pictures. Animations would take weeks of rendering.

Now I’m curious how fast LightWave can be on a PC with a 486 processor, because 486-based PCs could be purchased for about the same price as A1200 with the 68030 upgrade back in 1994/1995.

3D modeling in 1988

  • by

Long time ago (before I went to college and then got a job) I played a lot with 3D modeling software on PC. My favorite one was LightWave3D. Recently I tried its very beginning – there is something called VideoScape 3D which is kind of predecessor. In the package there is a small program Designer3D which (unlike other 1988 modelers for home micros) allows to make a 3D model using graphical interface instead of text commands.

You can see in the video how creepy the interface was. There are three viewports that cannot be resized or zoomed. I’ve modelled a simple “space ship” with only 20 polygons and it took me an hour to do this.

However, I see very interesting that there is a 10-page manual program that can describe all functions of the program so even somebody who never did anything in 3D can understand it. This is not so easy with today’s 3D modelers.

Amiga 2000

This is my only professional Amiga at home. Amiga 2000 is the first Amiga that has big case which is ready for inserting additional cards. In addition to Amiga-specific slots there are also standard 8-bit ISA slots known from IBM PC. However to enable them you have to insert a special PC emulation card which had price set to about a half of whole A2000 (basic one with 1 MB RAM and no hard drive).

The original one (which you can see above) is equipped with 4,7 MHz 8088 CPU, 512 kB RAM and CGA compatible video adapter. This card was bundled with PC-compatible 360kB 5.25” floppy drive, however there is emulation layer that allows you to share Amiga floppy/hard drives so it is not necessary.

This puppy is still waiting for some performance tests but it’s in a working condition.

Fixing and Cleaning Amiga 500

Another dead Amiga was repaired. There was necessary to replace a blown capacitor next to main CPU. We also cleaned the motherboard which was covered with some dirt.

A Bit of UNIX in Amiga

  • by

It is nice to see that so many Unix programs were ported to Amiga even when the computer was new. With Aztec C you can use familiar commands like ls, make and cc in Amiga Shell. I wanted something to plot data from our custom benchmarks and I’ve just discovered that Gnuplot still supports Amiga OS among other operating systems. Yay!
