Q3SphericalPoint_ToPoint3D

You can use the Q3SphericalPoint_ToPoint3D function to convert a spherical point to Cartesian form.

TQ3Point3D *Q3SphericalPoint_ToPoint3D (
const TQ3SphericalPoint *sphericalPoint, 
TQ3Point3D *result);

sphericalPoint

A spherical point.

result

On exit, a three-dimensional point.

DESCRIPTION

The Q3SphericalPoint_ToPoint3D function returns, as its function result and in the result parameter, the three-dimensional point that is the same point as the spherical point specified by the sphericalPoint parameter.
