Just a quick preview of what’s coming in the next update of graphics 2.0 that we’ll be seeding out soon to alpha testers.

It’s a feature known as normal mapping and it’s a workhorse technique for simulating lighting effects in traditional 3-D graphics. We’re repurposing it so this is trivial to do in Corona.

For example, here’s how how you can achieve a point light effect:

All effects have property knobs that you’ll be able to play with. In the point light, one of those knobs is the position of the point light. In the video below, we’re just moving the position in a circle:
