RemarksA bezier patch is defined by four bezier curves along its edges, four interior control points, and colors at each of the four corners. Given its grid of sixteen control points, a patch has a bezier curve for each of its four rows, and for each of its four columns. These cubic bezier curves determine the area filled by the patch, and its gradient color.
The colors in the interior are a bilinearly interpolated between the corner colors.
The sixteen Point fields in this struct are laid out as:
