Detailed Description

Cylindrical coordinate projection.

This class performs a cylindrical coordinate projection.

Cylindrical coordinates are: radius, theta (angle), height
Radius and height are 3D units and theta is in radians.

The projection of cylindrical coordinates into XYZ space is: x = r * cos(theta) y = r * sin(theta) z = h
