D3DXATTRIBUTEWEIGHTS structure

Specifies mesh weight attributes.

Syntax


typedef struct D3DXATTRIBUTEWEIGHTS {
  FLOAT Position;
  FLOAT Boundary;
  FLOAT Normal;
  FLOAT Diffuse;
  FLOAT Specular;
  FLOAT Texcoord[8];
  FLOAT Tangent;
  FLOAT Binormal;
} D3DXATTRIBUTEWEIGHTS, *LPD3DXATTRIBUTEWEIGHTS;

Members

Position

Type: FLOAT

Position.

Boundary

Type: FLOAT

Blend weight.

Normal

Type: FLOAT

Normal.

Diffuse

Type: FLOAT

Diffuse lighting value.

Specular

Type: FLOAT

Specular lighting value.

Texcoord

Type: FLOAT

Eight texture coordinates.

Tangent

Type: FLOAT

Tangent.

Binormal

Type: FLOAT

Binormal.

Remarks

This structure describes how a simplification operation will consider vertex data when calculating relative costs between collapsing edges. For example, if the Normal field is 0.0, the simplification operation will ignore the vertex normal component when calculating the error for the collapse. However, if the Normal field is 1.0, the simplification operation will use the vertex normal component. If the Normal field is 2.0, double the amount of errors; if the Normal field is 4.0, then quadruple the number of errors, and so on.

The LPD3DXATTRIBUTEWEIGHTS type is defined as a pointer to the D3DXATTRIBUTEWEIGHTS structure.
