directx – DeleteVertexShader dx8.1 to dx9 conversion

admin

i am currently trying to convert a game to use dx9 instead of dx8. I would say that i’m quite close to completing it, but I have a few errors that I don’t exactly know how to deal with atm.

  1. DeleteVertexShader and DeletePixelShader do not exist anymore in directx 9. What do I do with those? I could not find any equivalent to them in dx9 so far.
    Old code example:

D3D_CHECKERROR(hr); hr = _pGfx->gl_pd3dDevice->DeletePixelShader(ulHandle);

  1. Render state D3DRS_PATCHSEGMENTS does not exist anymore, it was used for the number of segments per edge when drawing patches. Do I need to replace it with something? I could not find any equivalent for this either.
    Code example:

    HRESULT hr = _pGfx->gl_pd3dDevice->SetRenderState( D3DRS_PATCHSEGMENTS, *((DWORD*)&fSegments));

These two issues are the ones I have the most struggles with atm, so any help would be appreciated.

Thanks in advance!
