This blog post is about feature 1, adding obj meshes into my scene. I used the videos that Chris provided as my guide for this feature.
Once I had the standard code to load a single object mesh into my scene, it was trivial to extend that code for multiple objects.
I have a loop in my OnDraw method that loops through all of the objects I have in my mesh array, drawing them one at a time. The code that I used for reading in obj files is the same code that Chris used, so there is nothing new on that side of things.
