just as we use .x files to include 3d meshes in directx what do we do to do the same in OpenGL ? and what are the utilities in which one can make these 3d meshes ?

I hate to be the one to have to break this to you, but unfortunately, OpenGL does not have any high-level functions such as OGL3DMesh.loadMesh()

Well, in OpenGL you have to do such things by hand! If you -really- want to support .X files, there is some documentation on the file format at Wotzit (Hosted by gamedev.net). The file format is getting quite ancient now though and I couldn''t see anyone actually -wanting- to support it!

sorry, kinda stupid question, but what is an mesh??

Mesh: noun. 1) The open spaces in a net, sieve or other criss-cross structure. 2) Material made like a net; Network.

In this context, a mesh is a series of polygons which if joined together using a series of invisible lines, they form a 3D object
