Q3PolarPoint_Set

You can use the Q3PolarPoint_Set function to set the components of a polar point.

TQ3PolarPoint *Q3PolarPoint_Set (
TQ3PolarPoint *polarPoint, 
float r, 
float theta);

polarPoint

A polar point.

r

The r component of the polar point.

theta

The q component of the polar point.

DESCRIPTION

The Q3PolarPoint_Set function returns, as its function result and in the polarPoint parameter, the polar point specified by the r and theta parameters.
