Image Description, by Jean-Francois Dube

Hi, this is a little software engine I did in my vacation week (entirly from scratch). Here are the software rasterizer features:
  • subpixel and subtexel accuracy
  • perspective correct texture mapping (every 16 pixels)
  • linear rgba vertex color interpolation
  • environment bump mapping ŕ la G400 & use the same bumpmap format (DUDV88).
  • You can download the demos at To run bumptest your desktop must be in 16 bits, and to run bumptest2 your desktop must be in 32 bits.

    Why Unreal is not interesting for me ?

    Cool SW effect, remembers me of my old software engine :) I loved to do SW rendering, and I included all those stuff (EMBM, bilinear, ZBuffer, etc., not all at the same time preferably, otherwise that was slow like hell :) ).

    Now I really enjoy using 3D hardware, because there's so much things to do with it... I really understand the need of working on SW rendering to understand the underlying mechanic, but for the final player I think that software rendering is just no more useable on PC platform... PLayers want kicking ass framerate with great looking graphisms, and so I believe that HW is the best way to achieve that. SW can be used for some specific platforms of course... happily :)

    Anyway, cool looking picture :)

    Sorry, my bad - I was referring to his first post.

    He's like a badass.

    Heaven 7 is realtime raytracing yes, BUT! only the edges/shadows are raytraced, everything else is texturemapped. (Atleast that's what it looks like)
