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.

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.

Last week on Corona Geek Hangout 149, Steven Johnson introduced us to creating custom shaders effects in Corona SDK. We explored what shaders are, why we might want to know more about them, and when we should consider using them. We also looked at some shader code examples to see the effects in action. Here are clips from the Hangout.

On today’s Corona Geek Hangout, Steven Johnson introduced us to vertex shaders as part 2 of our introduction the topic of creating and working with custom shader effects. We looked at several working shader playground examples and learned a tip for using wireframe mode with display.setDrawMode to see the points of a polygon in a vertex shader example.

Last week on Corona Geek Hangout 148, we stepped through the concepts and source code to create a motorized wheeled cart using pivot joints and Corona’s built in physics engine. We also explored applying torque and gravity to the cart to get some interesting effects. Here are clips to help you catch up. Download the examples from the Hangout to see how everything works.
