D3DVERTEXBLENDFLAGS enumeration
Defines flags used to control the number or matrices that the system applies when performing multimatrix vertex blending.
Syntax
typedef enum D3DVERTEXBLENDFLAGS {
D3DVBF_DISABLE = 0,
D3DVBF_1WEIGHTS = 1,
D3DVBF_2WEIGHTS = 2,
D3DVBF_3WEIGHTS = 3,
D3DVBF_TWEENING = 255,
D3DVBF_0WEIGHTS = 256
} D3DVERTEXBLENDFLAGS, *LPD3DVERTEXBLENDFLAGS;
Constants
-
D3DVBF_DISABLE
-
Disable vertex blending; apply only the world matrix set by the D3DTS_WORLDMATRIX macro, where the index value for the transformation state is 0.
-
D3DVBF_1WEIGHTS
-
Enable vertex blending between the two matrices set by the D3DTS_WORLDMATRIX macro, where the index value for the transformation states are 0 and 1.
-
D3DVBF_2WEIGHTS
-
Enable vertex blending between the three matrices set by the D3DTS_WORLDMATRIX macro, where the index value for the transformation states are 0, 1, and 2.
-
D3DVBF_3WEIGHTS
-
Enable vertex blending between the four matrices set by the D3DTS_WORLDMATRIX macro, where the index value for the transformation states are 0, 1, 2, and 3.
-
D3DVBF_TWEENING
-
Vertex blending is done by using the value assigned to D3DRS_TWEENFACTOR.
-
D3DVBF_0WEIGHTS
-
Use a single matrix with a weight of 1.0.
Remarks
Members of this type are used with the D3DRS_VERTEXBLEND render state.
Geometry blending (multimatrix vertex blending) requires that your application use a vertex format that has blending (beta) weights for each vertex.
