| * processing, FLOAT4 POSITIONT with fixed function, and FLOAT16 if |
| * GL_ARB_half_float_vertex is not supported. |
| * |
| * Note for d3d8 and d3d9: |
| * The vertex buffer FVF doesn't help with finding them, we have to use |
| * the decoded vertex declaration and pick the things that concern the |
| * current buffer. A problem with this is that this can change between |
| * draws, so we have to validate the information and reprocess the buffer |
| * if it changes, and avoid false positives for performance reasons. |
| * WineD3D doesn't even know the vertex buffer any more, it is managed |
| * by the client libraries and passed to SetStreamSource and ProcessVertices |
| * as needed. |
| * |
| * We have to distinguish between vertex shaders and fixed function to |
| * pick the way we access the strided vertex information. |
| * |
| * This code sets up a per-byte array with the size of the detected |
| * stride of the arrays in the buffer. For each byte we have a field |
| * that marks the conversion needed on this byte. For example, the |
| * following declaration with fixed function vertex processing: |
| * |
| * POSITIONT, FLOAT4 |
| * NORMAL, FLOAT3 |
| * DIFFUSE, FLOAT16_4 |
| * SPECULAR, D3DCOLOR |
| * |
| * Will result in |
| * { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR } |
| * [P][P][P][P][P][P][P][P][P][P][P][P][P][P][P][P][0][0][0][0][0][0][0][0][0][0][0][0][F][F][F][F][F][F][F][F][C][C][C][C] |
| * |
| * Where in this example map P means 4 component position conversion, 0 |
| * means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR |
| * conversion (red / blue swizzle). |
| * |
| * If we're doing conversion and the stride changes we have to reconvert |
| * the whole buffer. Note that we do not mind if the semantic changes, |
| * we only care for the conversion type. So if the NORMAL is replaced |
| * with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced |
| * with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some |
| * conversion types depend on the semantic as well, for example a FLOAT4 |
| * texcoord needs no conversion while a FLOAT4 positiont needs one |
