CONST_D3DDPFLAGS

The CONST_D3DDPFLAGS enumeration defines flags that are used to determine the behavior of the Direct3D rendering methods. These flags are used with the Direct3DDevice7.DrawPrimitive, Direct3DDevice7.DrawIndexedPrimitive, Direct3DDevice7.DrawPrimitiveVB, and Direct3DDevice7.DrawIndexedPrimitiveVB.

Enum CONST_D3DDPFLAGS
    D3DDP_DEFAULT = 0
    D3DDP_WAIT = 1
End Enum
D3DDP_DEFAULT
Perform normal rendering. (Return as soon as the polygons are sent to the card.)
D3DDP_WAIT
Causes the method to wait until the polygons have been rendered before it returns, instead of returning as soon as the polygons have been sent to the card. (On scene-capture cards, the method returns as soon as the card responds.) This flag is typically used for debugging. Applications should not attempt to use this flag to ensure that a scene is up-to-date before continuing.
