Just checking for DirectX version 9.0c is not sufficent as that version contains several revisions of the D3DX dlls. If a game ships with the April release the earlier versions of DirectX 9.0c will not work. How can the exact installed version be determined

      • Hello all! XNA doesn't seem to have functions for primitive creation. Thus, I am making my own. I have already made my own cube. Now I wish to make my own spheres. I'm thinking of making a geosphere instead of the normal kind since geospheres are more efficient. I presume that making a geosphere should come down to some sort of algorithm, but I cannot find anything on the net. If any

After I save this as a .x file, I could access each box as a limb of the main model. Doing a count for limbs would return 3, 0 being the model as a whole, 1 being one box, and 2 being the other.
