Using RayTK, you can produce some truly stunning math-based 3D (and 4D!) designs that easily translate to Volumetric LED displays. This workshop will teach you the fundamentals of producing and outputting real-time content, and mapping it to a live volumetric LED system.
RayTK is a library of components that act as a separate rendering system that uses raymarching and shaders instead of traditional TouchDesigner rendering. It supports things like infinitely repeating geometry, fractals, reflections and more.
Comprised of standard TouchDesigner components, RayTK operators can be wired together like traditional TouchDesigner operators to define complex shaders without writing any code. It can be incorporated into your existing workflows to create unique scenes with all the standard techniques that you're used to using in TouchDesigner like animation, midi mapping, and so on.
RayTK is free and open source! You will walk out knowing the fundamentals of RayMarching and having just enough RayTK knowledge to get lost in your own multi-dimensional creations without ever having to leave the comfort of the TouchDesigner node-based editor
Prior experience working with TouchDesigner IS required.
You will learn:
- Basics of how raymarching works
- How to install RayTK
- Creating raymarching scenes, with SDFs, transforms, materials, lighting, and more
- Creating 2D patterns
- Using scenes for volumetric LED displays (LedPulse Dragon O2)
