The thumbnail image is displayed in the Library panel, allowing you to preview the scene you're about to load. Check out the JavaScript Scripting page to learn more. This script will be run on every frame before the shader, calculating variables on a frame-wide basis and passing them into the shader as uniforms. To overcome some of these limitations, Synesthesia allows you to create an additional JavaScript scripting file called script.js. There is no memory of the previous frame, and you can't calculate anything on a "scene-wide" basis - every calulcation is limited to an individual pixel. JavaScript scriptįragment shaders are very powerful, but they have a few serious limitations. Check out the JSON Configuration page to learn more about all the options. It provides metadata like scene and artist names, specifies the controls that will render in the control panel, and allows added functionality like multiple passes, transitions, and texture loading. The scene.json file contains a JSON object that configures the scene. Synesthesia's core feature is custom audio uniforms - it automatically analyzes music in real-time and provides uniforms with audio data for each frame. To learn more about fragment shaders, check out the GLSL resources page - The Book of Shaders is a great place to start.īeyond standard GLSL, Synesthesia adds a host of built-in uniforms and functions, which are automatically available in every shader. This parallel technique is extremely powerful, allowing people to create incredibly complex visuals while maintaining high framerates. It is a fragment shader - a program that gets executed directly by a computer's GPU, rendering each pixel simultaneously based on its position in the frame. The code written in main.glsl generates all the imagery you see in Synesthesia. Read on to learn about the function of each part of the file structure.
