d3dx9: Implement adjacency in D3DXCreateSphere

[Nozomi Kodama]

Hello

Thank you for the feedback, Rico.

But, there is a problem with this patch.  Native d3dx9 does not call GenerateAdjacency. It hardcodes the adjacency. That is proved by the case D3DXCreateSpehere(device, 0.0f, 10,10,adjacency) where native gives different result using GenerateAdjacency or not. I need thinking more how to hardcode adjacency.


The side effect is to show there is a bug in our built-in GenerateAdjacency

Are the outer parentheses needed? Is the cast needed?

This may leak the temp ID3DXBuffer in the error case.
