Detailed Description

Generic hyperboloid primitive

The hyperboloid primitive is a parametric surface defined by revolving a line segment around the z azis. Given the hyperboloid is defined by points p0, p1 and parametric coordinates u and v:

fpreal theta = u * 2 * PI;
UT_Vector3D P = lerp(p0, p1, v);
x = P.x() * cos(theta) - P.y() * sin(theta);
y = P.z() * sin(theta) + P.y() * cos(theta);
z = P.z();
