Hello,

I'm looking a way to get the x,y,z coordinates of the intersection point

of a line through a volume. The line is defined by two points, one is

the origin.

One volume is a conic

_______

\_______/

/ \

/...........\

\___________/

Sorry it is not well drawn. It's a cone cut with paralle surfaces and

othogonal to the central axe. The axe is always vertical in my case.

So we have r1 and r2 for the two radius and h the height of the cone.

Volume 2 is obtained by a revolution around a vertical axis of a

polyline. The polyline is defined as a sequence of points.

I also need the transformation to get the u,v values for these volumes.

Note that mapping on the cone should not strech the texture.

Thanks in advance.
