Circle line-segment collision detection algorithm?
...e ray,
L is the end point of the ray,
C is the center of sphere you're testing against
r is the radius of that sphere
Compute:
d = L - E ( Direction vector of ray, from start to end )
f = E - C ( Vector from center sphere to ray start )
Then the intersection is found by..

What's the difference between dynamic (C# 4) and var?
