Q3PolarPoint_ToPoint2D

You can use the Q3PolarPoint_ToPoint2D function to convert a polar point to Cartesian form.

TQ3Point2D *Q3PolarPoint_ToPoint2D (
const TQ3PolarPoint *polarPoint, 
TQ3Point2D *result);

polarPoint

A polar point.

result

On exit, a two-dimensional point.

DESCRIPTION

The Q3PolarPoint_ToPoint2D function returns, as its function result and in the result parameter, the two-dimensional point that is the same point as the polar point specified by the polarPoint parameter.
