LygiaTD

This is a TouchDesigner native port of LYGIA Shader Library by Patricio Gonzalez Vivo.

Description

This repository is a statically built version of the library ~ and hence no internet connection is needed for file resolution during runtime. This version uses TouchDesigner's native include resolution mechanism for all the library's #include. The provided .tox file bundles all the files from the original libraries with modified paths and compliant names for it to work inside TouchDesigner.

Versioning

current version is v.1.2.3

This port will include static snapshots of the upstream repository and will be updated on every release porviding matching versions for each release.

Changelog / Divergences

• Imports do not have file extention but _glsl termination.
• Since his is a TD only version, there is no longer need to declare a SAMPLER_FNC before the imports. The default SAMPLER_FNC is now texture.

Usage

You can find along the .tox file a demo sandbox.toe project showcasing it's use. Mainly you need to make the .tox file to your project either via the global component library or by dragging it inside your project. Once the file is on your project, all works as expected with one main difference: file extensions for the {filename}.glsl programs become inside TouchDesigner a corresponding prepopulated textDAT named {filename}_glsl, hence your import will look as follows:

#include "filter/gaussianBlur_glsl"

as opposed to

#include "filter/gaussianBlur.glsl"

see attached figure.

Motivation

Shortly after the original library's release v1.0.0 a TouchDesigner version of it was published here by LeithBA. While the library works perfectly fine, it uses runtime web resolution for the files, which then makes having an internet connection available a requirement, on top of the overhead of such resolutions. On the other hand TouchDesigner has native include resolution at it's core. For those reasons I decided to bundle a native version of the library.

Details

The whole library is packaged by cloning the upstream source and parsing all the files, updating the include paths and populating the guts of several textDATs placed in their corresponding project hierarchy. The parsing script might be released opensource if there is enough interest.
