|
|
* 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
