30 /* Unlike the other templates here, this assumes quite a bit about the
31 * underlying hardware. Specifically it assumes a d3d-like vertex
32 * format, with a layout more or less constrained to look like the
33 * following:
34 *
35 * union {
36 * struct {
37 * float x, y, z, w;
38 * struct { char r, g, b, a; } color;
39 * struct { char r, g, b, fog; } spec;
40 * float u0, v0;
41 * float u1, v1;
42 * float u2, v2;
43 * float u3, v3;
44 * } v;
45 * struct {
46 * float x, y, z, w;
47 * struct { char r, g, b, a; } color;
48 * struct { char r, g, b, fog; } spec;
49 * float u0, v0, q0;
50 * float u1, v1, q1;
51 * float u2, v2, q2;
52 * float u3, v3, q3;
53 * } pv;
54 * struct {
55 * float x, y, z;
56 * struct { char r, g, b, a; } color;
57 * } tv;
58 * float f[16];
59 * unsigned int ui[16];
60 * unsigned char ub4[4][16];
61 * }
62 *
63
64 * VERTEX: hw vertex type as above
65 * VERTEX_COLOR: hw color struct type in VERTEX
66 *
67 * DO_XYZW: Emit xyz and maybe w coordinates.
68 * DO_RGBA: Emit color.
69 * DO_SPEC: Emit specular color.
70 * DO_FOG: Emit fog coordinate in specular alpha.
71 * DO_TEX0: Emit tex0 u,v coordinates.
72 * DO_TEX1: Emit tex1 u,v coordinates.
73 * DO_TEX2: Emit tex2 u,v coordinates.
74 * DO_TEX3: Emit tex3 u,v coordinates.
75 * DO_PTEX: Emit tex0,1,2,3 q coordinates where possible.
76 *
77 * HAVE_RGBA_COLOR: Hardware takes color in rgba order (else bgra).
78 *
79 * HAVE_HW_VIEWPORT: Hardware performs viewport transform.
80 * HAVE_HW_DIVIDE: Hardware performs perspective divide.
81 *
82 * HAVE_TINY_VERTICES: Hardware understands v.tv format.
83 * HAVE_PTEX_VERTICES: Hardware understands v.pv format.
84 * HAVE_NOTEX_VERTICES: Hardware understands v.v format with texcount 0.
85 *
86 * Additionally, this template assumes it is emitting *transformed*
87 * vertices; the modifications to emit untransformed vertices (ie. to
88 * t&l hardware) are probably too great to cooexist with the code
89 * already in this file.
90 *
91 * NOTE: The PTEX vertex format always includes TEX0 and TEX1, even if
92 * only TEX0 is enabled, in order to maintain a vertex size which is
93 * an exact number of quadwords.
