getPolarVec3

public Vec3 getPolarVec3(double r1,
                         double theta1,
                         double r2,
                         double theta2)

This is called to get a 3D vertex from the range points. The points are in strips. R1 increases the distance from the points to center axis of revolution r=f(z,theta) and z is = f(theta2) let theta2 range from 0 to height of image you need to build an array of radii like in TopFrame.java

Specified by:

getPolarVec3 in interface Vec3FunctionInterface

Parameters:

r1 - radius scale of cylinder

theta1 - sweep around center

r2 - unused

theta2 - sweep up center

Returns:

a point in cylinder coordinates

getDeltaTheta

public double getDeltaTheta()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
