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();

Examples:

A tube
PrimHyperboloid( UT_Vector3(1, 0, -.5), UT_Vector3(1, 0, .5), ...);
A cone
PrimHyperboloid( UT_Vector3(0, 0, -.5), UT_Vector3(1, 0, .5), ...);
A circle
PrimHyperboloid( UT_Vector3(0, 0, 0), UT_Vector3(1, 0, 0), ...);
