Test for collition bw two 3D bathematical shapes(Cube,sphere,culinder)

[lepton_veecee]

I have to find out whether two 3d shapes which are standard mathematical ones.I dint need the solution but i only need ,is  there a common solution or not.Am i wrong Comparing collision with Common solution?

There are many different algorithms with different performance trade-offs: http://graphics.stanford.edu/courses/cs164-09-spring/Handouts/paper_colldect_survey2.pdf

The easiest collision detection is between two spheres. Simply calculate distance between centers and if it's higher than sum of their radii, two spheres didn't collide.

In 3D computer graphics it's often used as 1st step for more detailed collision detection.

In those algorithms they need the point of collision, but here we don't need any information on points which have collided, we need to know if there is a collision or not.So my thought was as we can test linear equations for existence of non trivial solution, is there any way we can find it for 3d non linear objects
