hi, I know that there is a new interface firstly introduced by DX9, ID3DXFragmentLinker. I''m really happy to know that because programming shader in such a way is 100 times more flexible than the usual way, but... Does anyone ever tried using D3DXGatherFragmentsFromFile?? I found that there is no documentation nor example details how a "fragment" should be defined in a shader file, which NVidia (NVLINK) uses "#beginfragment" & "#endfragment" to do this trick. I even tried passing the whole file which is originally from SDK, but this function still failed. The following is how I implemented: HRESULT hr = D3DXGatherFragmentsFromFile( "my_shader.vsh", macroArray, NULL, D3DXSHADER_SKIPVALIDATION, &ppShader, &ppErrorMsgs ); Can anyone help?? I''m totally stuck! thanks so much in advance EdidaS

can anyone help?

MS posted their GDC powerpoint presentations yesterday. There was one that had a section on the fragment linker - look in "DirectX Shader Management - Craig Peeper.ppt". It gives examples of the fragment declaration. You can find the ppts Here.


Hope it helps,
Pinz
