Question

I am trying to load 3D models. How do I to read the data in the model file?

For an example, this is the data:

VERTICES
80 21 32
32 34 17
14 93 56
33 54 87
MODEL_SCALE 5

I know the data in 3D models is not like this, but how will I read the ‘vertex data’ and the ‘model scale amount’?

OpenGL doesn’t do this for you. You should write your own parser, store the readed datas into your defined data structures and use OpenGL primitives to render them.

Here’s a nice tutorial.
