Ok.  I am not sure how to approach this so I thought I would ask this
question.  How does one go about detecting collisions of 3d objects?  I am
building, for the fun of it, a 3d cannon fodder game and need collision code
for projectiles.  I also need a method for simulating a camera view that I
can move about.

Hi Alex,

Using bouding boxes is quite easy.

For sliding effects , you need ray and place checking after
bouding box or sphere check.

go to
There is a cool collison checking source there.

Collision checking isn't simple stuff.
For game, a little low accuracy can be accepted.


1. 3d object collision detection

 NN>       Get the free C++ package "Proxima", which can be found in
 NN> Gopherspace.
 NN> General high-speed polyhedral collision detection, no more, no less.


But what is Gopherspace? Is it an ftp site? Is this a package of source
I'm going to need a bit more info to get this package, but thanks!
I'm developing a 3d game, and the less time I have to spend re-inventing
the wheel by developing 3d code that others have already done, the sooner
I can get on with developing my game! :)
