About this episode

I'm back with a vengeance. A while ago, I realized that the domino thing was pretty boring, so that's on hold / given up on for now. I sort of had this idea for a racing game, but instead of doing that, I decided to download a model of a Lamborghini Diablo and try to import it into lul-engine. I had to make tons of modifications to the Blender export script (updating it to work with Blender 2.5, even) and to how the engine thinks of meshes, and then I threw in VBOs as well. Unfortunately, my application still sets all the material manually, because I wanted fine control over that. But here's how it worked out:1 VBO for the entire car model.9 matrix updates, because I ended doubling back to get the tires separate from the wheels. (10 if you include the camera)1 "uber-shader" for the entire car, which does diffuse, specular, and some two-tone stuff for every part.13 additional uniform updates that are used to change colors, adjust specular levels, and disable two-tone shading for most of the car except the paint.13 draw calls, but all from the same VBO so they should be pretty quick. And it is beautiful. The model didn't come with an interior, so I left the windows opaque. I also haven't set up the headlights and taillights, so it looks as though the painter forgot to cover them up, and painted right over the glass.
