Hi, In the last chapter of "OpenGL Game Programming", you are shown how to create a game engine and the game itself... And to perform the collisions, the radius of the bounding sphere is previously defined... so if I don''t know the radius of the object, I can''t perform this collision detection? Thanks

you normally calculate the bounding sphere or box after you loaded the vertices from a file or whatever.
if you don''t calc the bounding the simpengine, i think that was it''s name, checks the collision with the models position (because the radius ofthe sphere is zero)

i hope this helped you see you.
