Showing 3D models from different camera angles

  • My question pertains to this wiki article:

    This article is showing screenshots that look like exactly what I would like to do: render one model (loaded from an OBJ file) with multiple camera angles. Unfortunately, the code only shows how to render a model from one camera angle, so I have to conclude the screenshots were stitched together after the fact.

    I would like to know if it is possible to render the same model from multiple camera angles, without loading the OBJ file multiple times in separate views. My loading times are very slow, so I would prefer to preload all the model files first, and then open up the separate views for different camera angles later. Is this possible? I keep getting null pointer crashes.
