D3DRS_DELETERTPATCH

  • Article

This device driver interface (DDI) render state is one value of the D3DRENDERSTATETYPE enumerated type. It is used to delete rectangular or triangular patches from memory.

Render state value type Default value
DWORD None

Remarks

This render state notifies the driver that a patch is to be deleted. The value of this render state is the handle to the patch affected. All cached information should be freed and the handle should be removed from the driver's patch handle table. This render state is not API visible, but is generated internally by the API call DeletePatch. This render state is sent to the driver only when the API deletes patches explicitly. All other patches should be cleaned up when the device is destroyed.
