Collision Detection (3D Sphere to Triangle) - Need optimization/faster method

so any of you know any thing about 3D Sphere to Triangle Collision Detection i know a little but i need it to run faster.
this is the code i used:

VB Code:

Public Function STCD(TrianglePoint1 As D3DVECTOR, TrianglePoint2 As D3DVECTOR, TrianglePoint3 As D3DVECTOR, SphereCenter As D3DVECTOR) As D3DVECTOR

End Function

this is how it works it projects a point on to the plane of the triangle then projects that
point on to three other planes one for each edge of the triangle then figures out which
edge the point has passed.
if it does pass an edge then it gives the point that was projected onto that edge.
otherwise it gives the point that was projected on to the triangle.

Split from this similar thread.

Maybe its just me, but your variable naming could use some work. I can't really tell what is going on :/

chem

yes it is hard to understand but the values were in an array and i dont have
time to rename all of the values so if anyone understands it and can make it faster or just rename all of the values. if the game makes any money you may be payed i'll rename some of the values that i know.
