20 Converting Dimensions of Points and Vectors

20 Q3RationalPoint3D_To2D

You can use the Q3RationalPoint3D_To2D function to convert a three-dimensional rational point to a two-dimensional point.

TQ3Point2D *Q3RationalPoint3D_To2D (
const TQ3RationalPoint3D *point3D, 
TQ3Point2D *result);
point3D A rational three-dimensional point.
result On exit, a two-dimensional point.

DESCRIPTION


The Q3RationalPoint3D_To2D function returns, as its function result and in the result parameter, the two-dimensional point that corresponds to the rational three-dimensional point point3D.
