Point and Circle intersection in 3 D

[Adee]

Hi
I need some support regarding a problem.
I know the poistion of a point in 3D let say (sp,yp,zp) and I know the circle with Center (xc,yc,zc) having radius rc. My question is how to find the intersection point of the circle and a line in 3D.
I know that we can find the POI in 2 D by solving equation of line and circle but in 3 D its confusing for me ?

Your question is very confusing. You say that you are given a point and a circle. What line are you talking about? What does the given point have to do with this problem?

do have the exact question?

that doesn't make a heap of senese...

that said if you have a line & a circle in a 3D space, they don't necessarily have to intersect (nor in 2D either)
