Hi,if i use opengl GL_TRIANGLES to draw my mesh,can i just use the control points of my mesh to export the mesh file,not to triangulate this mesh at first!

By the way ,i know there is a way to make a mesh to be triangles,so if i want to use GL_TRIANGLE_STRIP in OPENGL to compose my mesh,so how should i do?

You can define meshes to use indirect indexes, which replicate a bit how strips are made, but this require you to setup vertices with two array (one for indices, and another for the vertices).

All of our sample code use this way of storing vertex data. Its called Index to Direct mapping. If you check ExportScene03, we build a pyramid that way.
