|
|
*
|
|
* The vertex buffer FVF doesn't help with finding them, we have to use the decoded vertex declaration and pick the things

* We have to distinguish between vertex shaders and fixed function to pick the way we access the

* 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
