I'm developing an Android application with OpenGL ES 2.0.
I want to load an export made with Blender 2.49b in Wavefront OBJ format. I have identified verxtex position, normal and texture.
I want to use glDrawElements(GLenum mode, GLsizei count, GLenum type, const GLvoid *indices) to draw my mesh but I don't know how I can obtain the last parameter, indices, from a Wavefront OBJ file.
Are faces the 'indices' that I'm looking for?
I've found this on a forum:
faces = indices starting with 1!
What is the meaning of 'starting with 1!'?
