I am having a Three
OBJ file ,
Cone , Sphere and Cube. How can i find the dimension of these objects , so that i can use it in my collision detection class.
i.e How can i find
Radius , Length of Cube and Radius and Height of cone.
Or is there any better way for collision detection , I have Hundreds of random particle in my game which may or maynot collide with these objects.
