Direct3D (DirectX 9.0) Code Samples - Page 5

This sample demonstrates how to eliminate z-fighting when rendering polygons directly on top of other polygons  by using Direct3D's D3DRS_SLOPESCALEDEPTHBIAS and D3DRS_DEPTHBIAS render states.

Relevant Keywords: SetRenderState, D3DRS_SLOPESCALEDEPTHBIAS, and D3DRS_DEPTHBIAS.

Demonstrates how to manually modify the view matrix using mouse and keyboard input to create a First Person Shooter style control. This sample is very similar to the "First-Person-Shooter View Control" sample except this one uses no DirectInput. Check out the OpenGL source code page for the OpenGL equivalent of this sample.

Relevant Keywords: SetTransform, D3DXMatrixPerspectiveFovLH, D3DXMatrixRotationAxis, D3DXVec3TransformCoord, D3DXMatrixScaling, D3DXMatrixIdentity, D3DXVec3Normalize, D3DXVec3Dot,  D3DXVec3Cross, D3DXLoadMeshFromX, GetBufferPointer, DrawSubset, D3DXMATERIAL, D3DXMESH_SYSTEMMEM, D3DTS_VIEW, D3DTS_WORLD, D3DTS_PROJECTION, LPD3DXMESH, MatD3D, pTextureFilename, Ambient, and Diffuse.
