20 Converting Dimensions of Points and Vectors

20 Q3Point3D_To4D

You can use the Q3Point3D_To4D function to convert a three-dimensional point to a four-dimensional point.

TQ3RationalPoint4D *Q3Point3D_To4D (
const TQ3Point3D *point3D, 
TQ3RationalPoint4D *result);
point3D A three-dimensional point.
result On exit, a rational four-dimensional point.

DESCRIPTION


The Q3Point3D_To4D function returns, as its function result and in the result parameter, the rational four-dimensional point that corresponds to the three-dimensional point point3D.
