20 Transforming Points and Vectors

20 Q3Param2D_Transform

You can use the Q3Param2D_Transform function to apply a transform to a two-dimensional parametric point.

TQ3Param2D *Q3Param2D_Transform (
const TQ3Param2D *param2D, 
const TQ3Matrix3x3 *matrix3x3, 
TQ3Param2D *result);
param2D A two-dimensional parametric point.
matrix3x3 A 3-by-3 matrix.
result On exit, the point that is the result of multiplying param2D by matrix3x3.

DESCRIPTION


The Q3Param2D_Transform function returns, as its function result and in the result parameter, the parametric point that is the result of multiplying the parametric point param2D by the matrix transform matrix3x3. Note that on entry the result parameter can be the same as the param2D parameter.
