Q3SphericalPoint_Set

You can use the Q3SphericalPoint_Set function to set the components of a spherical point.

TQ3SphericalPoint *Q3SphericalPoint_Set (
TQ3SphericalPoint *sphericalPoint, 
float rho, 
float theta, 
float phi);

sphericalPoint

A spherical point.

rho

The r component of the spherical point.

theta

The q component of the spherical point.

phi

The f component of the spherical point.

DESCRIPTION

The Q3SphericalPoint_Set function returns, as its function result and in the sphericalPoint parameter, the spherical point specified by the rho, theta, and phi parameters.
