On today’s Corona Geek Hangout, Steven Johnson from Xibalba Studios introduced us to shaders, what they are, and when we might use them. We even looked at several working shader playground examples to see the code in action.
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!
Right now, many of you are probably trying to figure out whether you want to upgrade to Pro right now, and lock in our promotion before it ends and prices go up this Wed (May 1).
So this week, I wanted to sit down and talk to you about the difference between Starter and Pro features.
In addition, I want to talk about cool graphics features coming to Pro developers that will make mobile app development breathtakingly awesome.
