New release: 3D Engine 2.5

Donnerstag, 10. September 2020

3D Engine 2.5 is now released!

Improvements in Version 2.5:
– exported obj-files have to contain the face-normals.
– rendertime is reduced by another 40%
– you can render bigger model up to ~2800 verts, because of overall reduced code (20% less).
– reworked user-interface. The parameter-values are typed in directly now.
– arrays are dimensioned according to the available memory.
– improved render precision, because the face-normals are imported and not calculated any more.

3D Engine 2.0

Dienstag, 4. August 2020

A new release 2.0 of my 3D Engine is now available.

I constantly improved the engine over the last year. The engine renders now 30% bigger models and the rendertime is reduced by 60%.

Yesterday the SpaceX Crew Dragon Spaceship successfully returned to earth and starting a new era of spaceflight. As a reminder of this important event, the modeldata of the „SpaceX Crew Dragon“ is included.

Solid States (Atari 800 3D-engine) conversion

Samstag, 1. August 2020

While reading about the history of 3D graphics on homecomputers, the program „Solid States“ for the Atari 800 from Tom Hudson was mentioned. Tom Hudson co-developed CAD-3D (1986) and Cyber Studio (1987) for Atari ST and then the famous 3D Studio (1990) for PCs. „Solid States“ is written in ATARI-BASIC and listed in the magazine „Analog“ in Feb. 1984 #16. As a fan of early 80’s 3D graphics i ported a part of code to the plus/4, leaving out the plotting and disk-operations. You find downloadlink of the plus/4 code and the link to the magazine below the screenshot.

Animated 3D model

Mittwoch, 4. Dezember 2019

I did my first 3D animation. I optimized my 3D-engine with the Shell-Sort algorithm. So many renderings in a short time are possible. This was done in one hour. The screens were combined in an animated GIF.

7th place at AROK 2019 in the wild competition!

Sonntag, 4. August 2019

My friend MMS from the plus/4 scene came up with the idea of making a slide show und do an entry for the wild competition at AROK 2019 (3. August in Hungary). He made the slide show, i provided the the graphics from my new 3D-Basic engine. Finally we got the 7th place and a big applause during the presentation. Not bad for the first time!

If you reverse the colors (line 40) you get nice filled polygons.

3D Engine works on the commodore 128

Montag, 24. Juni 2019

Today i tested the 3D-engine in VICE for the commodore 128. It works without any changes. Good news for C 128 fans. Since it has 128 kB RAM even more complex renderings should be possible.

3D Engine Video Tutorial

Samstag, 22. Juni 2019

In this small video tutorial i explain how to make your own 3D objects for the engine in Blender. I decided to speak German, but you will also understand most things just by watching. Have fun, just be creative and show your work if you like. I will post it here in my blog.

3D Engine (Basic 3.5)

Donnerstag, 20. Juni 2019

My first release of  the 3D engine.

Consider it as an experiment, play around with the objects and the code. Improve it and port it to all plattforms you want. Thank you all for your support and nice words, which inspired me to get this project so far.
