Making an RGB Controller I have been looking for an hardware device as a tactile interface for 3D software applications. There is a large choice of commercial midi controllers that can be used to interface with software applications. Some adventurous people even design their own controllers from the ground up. Somehow, that's the path
Pixel Compositor In the previous post, I presented the pixel composition feature in Pico Pixel. In this post, I introduce the pixel compositor interface and how it is managed. At the core, a pixel composition is a set of pixel shaders running sequentially over a quad polygon. Execution of a single pixel
Shaders Pico Pixel uses shaders to display textures. Two triangles and a texture is all that is needed for Pico Pixel to display an image. And the shaders it uses are very simple. There is a request on PixelAndPolygon twitter feed to give the user control over the rendering shaders in
