In the last video of each recording session we don't plan in advance what we want to show, but improvise and see where things go.

That means you get to see our process instead of learning about the most optimized way of doing something.

In this 4th video of the shading series we explore how to pass an image into a GLSL shader and how to read its pixel colors.

And remember: With step() and smoothstep(), "edges always first"! 😃. We made the same mistake twice of entering the "edge" value as the second argument. See https://thebookofshaders.com/glossary/?search=smoothstep

In this third video of the shading series we get a bit more into GLSL shaders.

Take a look at https://thebookofshaders.com/ to learn more about fragment shaders.

In the second video of the shading series we get into writing our own shader effects using shadeStyle and fragmentTransform. We also take a look at how to pass data into the shader using the parameter() method, which sets a GLSL uniform variable.

This is the first video in the shading series. To start easy they play with orx-shade-styles and specifically with linear and radial gradients. In following videos they get into writing their own shader effects instead of using existing ones.

In this video they play with line segments, their rendering and computing intersections between them.
