D3DDDIARG_DRAWRECTPATCH structure (d3dumddi.h)
The D3DDDIARG_DRAWRECTPATCH structure describes a rectangular patch to draw.
Syntax
typedef struct _D3DDDIARG_DRAWRECTPATCH {
[in] UINT Handle;
} D3DDDIARG_DRAWRECTPATCH;
Members
[in] Handle
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 D3DRECTPATCH_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 DrawRectPatch function that use the same handle to run more efficiently.
