Fields

dwSize

Size of the class, in bytes.

lpIn

Array variable that contains the vertices to be transformed.

dwInSize

Stride of the vertices to be transformed.

lpOut

Array variable that receives the transformed vertices.

dwOutSize

Stride of output vertices.

lpHOut

Array variable that contains homogeneous transformed vertices.

dwClip

One or more values of D3DCLIP_ type, specifying how the vertices are clipped.

dwClipIntersection

One or more D3DSTATUS_CLIPINTERSECTION* values of D3DSTATUS_ type, denoting the intersection of the clip flags.

dwClipUnion

One or more D3DSTATUS_CLIPUNION* values of D3DSTATUS_ type, denoting the union of the clip flags.

x1, y1, x2, and y2

Values that defines the extent of the transformed vertices. These fields are filled by the transformation module with the screen extent of the transformed geometry. For geometries that are clipped, this extent will only include vertices that are inside the viewing volume.

Each input vertex should be a three-vector vertex giving the [x y z] coordinates in model space for the geometry. The dwInSize field gives the amount to skip between vertices, allowing the application to store extra data inline with each vertex.

All values generated by the transformation module are stored as 16-bit precision values. The clip is treated as an integer bitfield that is set to the inclusive OR of the viewing volume planes that clip a given transformed vertex.
