/* 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. |
