/* Explanation of texture copying via drawShadedTexQuad and drawShadedTexSubQuad:
|
|
From MSDN: "When rendering 2D output using pre-transformed vertices,
|
|
care must be taken to ensure that each texel area correctly corresponds
|
|
to a single pixel area, otherwise texture distortion can occur."
|
|
=> We need to subtract 0.5 from the vertex positions to properly map texels to pixels.
|
|
HOWEVER, the MSDN article talks about D3DFVF_XYZRHW vertices, which bypass the programmable pipeline.
|
|
Since we're using D3DFVF_XYZW and the programmable pipeline though, the vertex positions
|
|
are normalized to [-1;+1], i.e. we need to scale the -0.5 offset by the texture dimensions.
|
|
For example see a texture with a width of 640 pixels:
|
|
"Expected" coordinate range when using D3DFVF_XYZRHW: [0;640]
|
|
Normalizing this coordinate range for D3DFVF_XYZW: [0;640]->[-320;320]->[-1;1]
|
|
i.e. we're subtracting width/2 and dividing by width/2
|
|
BUT: The actual range when using D3DFVF_XYZRHW needs to be [-0.5;639.5] because of the need for exact texel->pixel mapping.
|
|
We can still apply the same normalizing procedure though:
|
|
[-0.5;639.5]->[-320-0.5;320-0.5]->[-1-0.5/320;1-0.5/320]
|
|
|
|
So generally speaking the correct coordinate range is [-1-0.5/(w/2);1-0.5/(w/2)]
|
|
which can be simplified to [-1-1/w;1-1/w].
|
|
|
|
Note that while for D3DFVF_XYZRHW the y coordinate of the bottom of the screen is positive,
|
|
it's negative for D3DFVF_XYZW. This is why we need to _add_ 1/h for the second position component instead of subtracting it.
|
|
|
|
For a detailed explanation of this read the MSDN article "Directly Mapping Texels to Pixels (Direct3D 9)".
