Synthclipse allows you to develop shaders in two ways: Using Fragx shaders or JSX scripts. Below is short description and comparison of both methods. More detailed informations can be found in dedicated sections in the left menu.
Fragx shaders are executable Fragment Shader files with .fragx or .stoy extensions. They are ordinary GLSL Fragment Shaders extended with metadata used in comments. The idea of using metadata in shaders comes from Mikael Hvidtfeldt Christensen and his Fragmentarium.
