Q3RationalPoint4D_To3D

You can use the Q3RationalPoint4D_To3D function to convert a four-dimensional rational point to a three-dimensional point.

TQ3Point3D *Q3RationalPoint4D_To3D (
const TQ3RationalPoint4D *point4D, 
TQ3Point3D *result);

point4D

A rational four-dimensional point.

result

On exit, a three-dimensional point.

DESCRIPTION

The Q3RationalPoint4D_To3D function returns, as its function result and in the result parameter, the three-dimensional point that corresponds to the rational four-dimensional point point4D.
