Make a start on alias model rendering. The vertex and fragment shaders are written, and R_InitAlias is stubbed, but that's it so far.

uniform mat4 mvp_mat;
Load the alias model shaders.
2012-01-02 02:18:34 +00:00
uniform mat3 norm_mat;
Load all the alias vertex data as bytes. I had forgotten I wanted to do it this way.
2012-01-02 04:41:12 +00:00
uniform vec2 skin_size;
Rework the alias vertex shader and rendering code for lerping. Lerping isn't actually done yet (need to get both poses and blend), but this still renders correctly with blend forced to 0.0.

st = mix (vsta, vstb, blend) / skin_size;
Upload the normals with the vertex data. Not all hardware can access a texture sampler from the vertex shader, and I don't want multiple paths this early in the game. Now, vertex normals are uploaded as shorts. Should be 14 bytes per vertex (was 10, could have been 8 if I had put the normal index with the vertex rather than st).
