Circle line-segment collision detection algorithm?
...'ve simplified the problem to 2D here, the solution we get applies also in 3D
to get:
Expand
x2 - 2xh + h2 + y2 - 2yk + k2 - r2 = 0
Plug
x = ex + tdx
y = ey + tdy
( ex + tdx )2 - 2( ex + tdx )h + h2 +
( ey + tdy )2 - 2( ey + tdy )k + k2 - r2 = 0
Explode
ex2 + 2extdx + t2dx2 - 2exh - 2tdxh + h2 ...
