| /* Unlike the other templates here, this assumes quite a bit about the |
| * underlying hardware. Specifically it assumes a d3d-like vertex |
| * format, with a layout more or less constrained to look like the |
| * following: |
| * |
| * union { |
| * struct { |
| * float x, y, z, w; |
| * struct { char r, g, b, a; } color; |
| * struct { char r, g, b, fog; } spec; |
| * float u0, v0; |
| * float u1, v1; |
| * float u2, v2; |
| * float u3, v3; |
| * } v; |
| * struct { |
| * float x, y, z, w; |
| * struct { char r, g, b, a; } color; |
| * struct { char r, g, b, fog; } spec; |
| * float u0, v0, q0; |
| * float u1, v1, q1; |
| * float u2, v2, q2; |
| * float u3, v3, q3; |
| * } pv; |
| * struct { |
| * float x, y, z; |
| * struct { char r, g, b, a; } color; |
| * } tv; |
| * float f[16]; |
| * unsigned int ui[16]; |
| * unsigned char ub4[4][16]; |
| * } |
| * |
| |
| * VERTEX: hw vertex type as above |
| * VERTEX_COLOR: hw color struct type in VERTEX |
| * |
| * DO_XYZW: Emit xyz and maybe w coordinates. |
| * DO_RGBA: Emit color. |
| * DO_SPEC: Emit specular color. |
| * DO_FOG: Emit fog coordinate in specular alpha. |
| * DO_TEX0: Emit tex0 u,v coordinates. |
| * DO_TEX1: Emit tex1 u,v coordinates. |
| * DO_TEX2: Emit tex2 u,v coordinates. |
| * DO_TEX3: Emit tex3 u,v coordinates. |
| * DO_PTEX: Emit tex0,1,2,3 q coordinates where possible. |
| * |
| * HAVE_RGBA_COLOR: Hardware takes color in rgba order (else bgra). |
| * |
| * HAVE_HW_VIEWPORT: Hardware performs viewport transform. |
| * HAVE_HW_DIVIDE: Hardware performs perspective divide. |
| * |
| * HAVE_TINY_VERTICES: Hardware understands v.tv format. |
| * HAVE_PTEX_VERTICES: Hardware understands v.pv format. |
| * HAVE_NOTEX_VERTICES: Hardware understands v.v format with texcount 0. |
| * |
| * Additionally, this template assumes it is emitting *transformed* |
| * vertices; the modifications to emit untransformed vertices (ie. to |
| * t&l hardware) are probably too great to cooexist with the code |
| * already in this file. |
| * |
| * NOTE: The PTEX vertex format always includes TEX0 and TEX1, even if |
| * only TEX0 is enabled, in order to maintain a vertex size which is |
| * an exact number of quadwords. |
