Corona Geek #153 – Custom Shader Math and 2D Shadow Effects

Today, Steven Johnson of led us through part 4 of our ongoing discussion on creating custom shader effects. During the Hangout Steven highlighted some of the exponential numerical issues surrounding shader math. We looked at a few visual representations of these “numerical issues” and talked about how to overcome hardware limitations to achieve device level precision.

Hangout Highlights – Custom Vertex Shaders and Visualizing Polygon Points

Last week on Corona Geek Hangout 150, Steven Johnson introduced us to creating custom vertex shaders effects in Corona SDK. We also looked at some shader code examples to see the effects in action and we revealed a tip for using wireframe mode with display.setDrawMode to see the points of a polygon in a vertex shader example. Here are the clips from the Hangout.

Mac App and Win32 App: Open Beta

At the beginning of this year, I outlined new platforms as a major theme for 2015. And a few months later, at GDC, we announced bringing Mac App and Win32 App support to the Corona platform. Since then, we’ve been conducting private betas with a small group of Corona developers.

Today, we are opening up the Mac App and Win32 App betas to everyone in the Corona community!
