_D3DDDIARG_DRAWTRIPATCH structure

Description

The D3DDDIARG_DRAWTRIPATCH structure describes a triangular patch to draw.

Members

Handle [in]

The handle to the patch surface.

Remarks

The Handle member refers to the patch surface, so that the next time the patch surface is drawn, the Microsoft Direct3D runtime is not required to re-specify the D3DTRIPATCH_INFO data structure for the patch surface. The user-mode display driver can precompute and cache forward-difference coefficients and any other information, which allows subsequent calls to the driver's DrawTriPatch function that use the same handle to run more efficiently.
