help - rotating a point

Post by Alex Moh » Tue, 25 Mar 1997 04:00:00

Perhaps stupid, but here's my problem:

How can I rotate a point on the unit
sphere about an arbitrary axis through
the origin?

Thank you to anyone who can help.


1. Rotating a point around another point(silly me)

        I need to rotate a point (px,py,pz) around the Y-axis of another
point.  This is probably rilly rilly rilly simple but I'm awful at math.
:(  And it's been a long time since HS/college.
        A little basic/C code would be great.
