Tired of searching for the same functions over and over? or to port and reimplementing them between platforms and shader languages? LYGIA is shader library of reusable functions that can be include easily on your projects. Lygia was created by Patricio Gonzalez Vivo.

**FOLDERS** is a simple component that creates folders in the local directory relative to the project folder.   Since a number of my components have default locations for externally synced tables,

Recently rediscovered this post from several years ago. Needing to calculate the White value for a color to drive lighting fixtures that expect RGBW channels is pretty common. Since it's basic color math, it's something that's really best done in a shader.

Here's a quick implementation of a physarum system, using no GLSL at all. I doubt that it's easier to understand tbh. Non commercial use only.

.PHOTOGRAMMETRY WORKSHOP.   Last May, I gave a workshop about photogrammetry @ Stereolux (France - 44)   The ZIP archive is now available, with 3D scans (xyz text format - made with Reality Capture) and an associated Toe file (the one used to make the teaser image).

This is a boilded down version of my Serum system (example). It's a 2D particle system and there's no GLSL involved! Feel free to play around and be inspired. Always credit me when sharing results. Non-commercial use only, contact me otherwise.

Distance Calculator Simple COMP to calculate a distance between two coordinates.   How to use Drag and drop the Distance_Calculator.tox on your project. Connect two CHOP operators to each of the inputs. You don't have to rename the channels.     Just arrange the channels by xyz.
