Hi
Ok, I haven=92t tried this yet, but will do it soon (need to
fix some pending issues in the graphics engine!)=85meanwhile if somebody
is desperate, can try this for capped cylinder.
=20
Assume the cylinder axis is along the X-Axis. First
transform the other primitive to the capped cylinders local coordinate
system. Do a spherical test along Y and Z axis. Along X-axis do an AABB
test for the X-Axis planes. i.e sphere test along Y and Z axis and two
plane test for the X-axis planes (the caps).=20
Retransform the contact points back to original coordinate system.

Ps: I would like to hear from ppl who have already tried this, also
would like to know if there are any other methods.

Have a nice Dynamix!
