Microsoft DirectX 8.0 (C++)

Blending Transform and Render States

The IDirect3DDevice8::SetTransform method recognizes the D3DTS_WORLD and D3DTS_WORLDn macros, which correspond to values that can be defined by the D3DTS_WORLDMATRIX macro. These macros are used to identify the matrices between which geometry will be blended.

The D3DRENDERSTATETYPE enumerated type includes the D3DRS_VERTEXBLEND render state to enable and control geometry blending. Valid values for this render state are defined by the D3DVERTEXBLENDFLAGS enumerated type. If geometry blending is enabled, the vertex format must include the appropriate number of blending weights.
