be2003's Yeti3D PSP port |
Ó
Homebrew coder be2003 has just announced the recent release of the PSP port of Yeti3D. In case you guys are wondering what this application is, Yeti3D is a 3D engine originally built by Derek Evans for the Game Boy Advance back in 2003.Be2003 notes is that this version isn't dependent on SDL - it's a pure PSP port. Here's a glimpse of the engine's technical notes (for the sake of the curious devs):
- The current viewport is 120x80 pixels, 15bit.
- All textures are 64x64 8bit.
- Textures are converted to 15bit via a pre-calculated lighting LUT.
- Polygons can be any convex shape. Only squares are currently used.
- Each vertex is described as X, Y, Z, U, V and brightness.
- The renderer uses 24:8 fixed point maths.
- Polygons are clipped in 3D space using 45 degree planes. Distance to plane calculations therefore use only additions and subtractions.
- Polygon edges are clipped using one divide and 6 multiplies.
- 4 clipping planes are used. No front plane is required. No back plane is used.
- No per-span clipping is used. Fixed point errors are hidden offscreen.

Cool, nice port. Thanks!
Killer App man, this is going to be fun to play with and I'm sure this took you quite a while to create. Thanks for your effort and kindness to release here for all of us to use.
This is a great port. It runs very smoothly, and I can see it going a long way if you are willing to put some work in to it.
I close my eyes..... only for a moment and the moments gone....
..but why did you choose this version of Yeti? GBA's Port wasn't really a good one in the first place and prefered the original or Pocket Pc version's instead. Here's a link to the Pocket Pc version, it should be easy to compile: http://www.picsprint.com/intuitex/yeti.html Or better yet, why not make yourself a challenge with the Fully updated version of this engin... CUBE! It's an excellent engine on it's own and has the source file for you to play around with, along with a game ;)! Now it really wouldn't be hard to do as *cough* a pocket pc version was compiled before. Here's a link to Cube if you want to check it out: http://cubeengine.com/ Now don't try to do CUBE 2, it's fairly new and may create too much of a challenge for you. It is very pretty though and if you were able to port it, I would be very impressed :)! But back to your current port... good job but my comments above might make things even better for you ;)!
just btw... the viewport is 480x272 alothough it uses 5551 for color. thanks for the links, ive been looking for something else to port, i just ported yeti because it looked quick and easy, lol
perhaps his sarcasm was a little understated.
This is nice man, thanks be2003. I didn't know about yeti3d till now. From what I have googled, its still just an engine, no games have been developed for it?
