Hi! I am working on a 3D RTS. It`s not much right now. I have a moving camera and selectable units. I just started to work on a collision detecton system. I would like to now what kind of collision detection algorithms are used in commercial RTS games ( Age of Mithology, Warcraft, Total Anihilation ). If you are familiar with this topic I would appreciate your input. Thanks.

A quick google search will give you thousands of results for collision detection. There are also quite a few articles on CD on GameDev.

Articles -> Game Programming -> Collision Detection

I couldn't tell you about what techniques the games you mentioned use, since i don't know, but all 3D space collisions are handled in similar ways.

Yuo might also want to do a bit of research into bounding volumes. I recommend this link to get you started:

I have read the CD tutorials on GameDev and also a lot of tutorials on other web pages.
The problem is that these tutorials usualy aproach the CD issue from a FPS perspective. This makes it difficult to understand what CD system would fit best a RTS game.
I found the page pointed by you really helpful, if brought some light.
Thanks!

Well, in Warcraft 3 they use numbers to represent different tiles. (I.E. 1 for walkable, 2 for non-walkable, 3 for water, 4 for ??????, etc.)

The best thing to do is just choose whatever you think you'd prefer, and go for it. -Promit

I used OPCODE for my collision detection:

Should work okay for your RTS game.
