Description: 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.<br><br>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):<br><br>The current viewport is 120x80 pixels, 15bit.<br>All textures are 64x64 8bit.<br>Textures are converted to 15bit via a pre-calculated lighting LUT.<br>Polygons can be any convex shape. Only squares are currently used.<br>Each vertex is described as X, Y, Z, U, V and brightness.<br>The renderer uses 24:8 fixed point maths.<br>Polygons are clipped in 3D space using 45 degree planes. Distance to plane calculations therefore use only additions and subtractions.<br>Polygon edges are clipped using one divide and 6 multiplies.<br>4 clipping planes are used. No front plane is required. No back plane is used.<br>No per-span clipping is used. Fixed point errors are hidden offscreen.<br><br>Full technical notes, installation/usage details, and contact addresses are available in the file README - we strongly advise would-be users to check those out before using this application. There's also the matter of the bundle GNU license, which guys here will need to read as well.
