The newer version which uses image2D texture to track positions is encouraged and located here: https://github.com/Roonil/NCS_Spectrum_GLava

NCS_Spectrum_GLava

This is an attempt to replicate the well-known NCS Spectrum Audio Reactor, implemented for GLava. This is a fragment shader comprising of 9 buffers, and may prove to be a little GPU-intensive, but looks aesthetically pleasing anyways :)

Installation Instructions

1. Ensure that GLava is set-up and running properly, using THIS render.c as source file (changes .name = "screen" to .name = "time" at line 586) to ensure that time variable works properly: https://github.com/jarcode-foss/glava/pull/121/commits/08a7f7c169a0a4cb72412485b2d21aff26d2c191
2. Clone the repository and copy the 'ncs' folder into home/config/glava directory.
3. Run the module with glava -m ncs (Suggested resolution in rc.glsl: 370x370)
