hi, i have created a terrain using c and opengl. now i wish to place some objects like a tree or cattle on the terrain. how do i do it? can it be done using opengl??

Yes it can, anything can be done if you put your mind to it!

Cattle you say?

Depending on how you are rendering your terrain, e.g. heightmap you can just use those values and displace the model mesh by that value to move the mesh over the terrain at each vertex.

Or if you are using a Physics lib, e.g. PhysX you can have PHysX do it for you and many other things if you want.

yes i am using a heightmap array, and i have a model of the cattle/man which i want on the terrain.
