I have a Parametric Equation for a Cone:(adsbygoogle = window.adsbygoogle || []).push({});

x=u

y=cos(v)*a*(u-h)/h

z=sin(v)*a*(u-h)/h

where:

h is height of the cone

a is the Radius of the Base

u goes from 0 to h

v goes from 0 to 2*pi

This cone lies on the x-axis. I need it to lie on the theta and phi axis. This is what I came up with to transform it:

|x1| |cos(theta)*cos(phi) sin(phi) sin(theta)*cos(phi) | |x|

|y1| = |sin(theta)*cos(phi) cos(theta)*cos(phi) sin(phi) | = |y|

|z1| |sin(phi) sin(theta)*cos(phi) cos(theta)*cos(phi)| |z|
