Tutorial: Paint Brushes, Trailing Object Effects, and More with the Snapshot Canvas

Today, I’m going to show you how to use snapshots to achieve the sorts of tricks you’d want to do in traditional CPU-based graphics.

One of the old school tricks is to be able to touch pixels on the frame buffer directly, or modify the pixels of an image directly. In a GPU world, you cannot do that b/c passing memory between the CPU and GPU is extremely expensive.

Snapshots to the rescue!

3-D effects with Normal Mapping

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

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.
