GLSL helpers

A reusable asset to bring GLSL helper functions into your TouchDesigner project.

Usage

To use, simply drag the release/glsl.tox file into your project. Alternatively you can download the same file from the github release page.

Including in a GLSL TOP

To include the code you can directly include using the #include directive in your GLSL code.

#include "/project1/glsl/helpers"

Please note this path will change depending on where you place the asset. To make it location agnostic create a select DAT and set DAT path to expression mode and type op.glsl.op("include_helpers"). You can now use that select DAT as the Preprocess Directives DAT in your GLSL TOP

Adding custom functions

You can add custom functions and defines by creating valid glsl code in a text DAT and connecting it to the COMP's Custom GLSL field on the Config page. Please note that to have your functions definitions show up in the helper list you must use tabs rather than spaces.

Viewing functions

You can get a list of the functions by viewing the table ./functions. In python you can call the function op.glsl.ListFunctions() to get a list of the names of the functions.
