Hi!

In this tutorial you'll learn how to make instanced particles react to the surface of  geometry created with raymarching technique (signed distance function (SDF) to be precise).

Low-intermediate GLSL & intermediate TouchDesigner skills are required. Here is the list of (a lot) of other resources I mentioned in this video):

• My raymarching tutorials 
• Bruno Imbrizi's tutorial on curl noise 
• Similar technique in vvvv, Houdini, WebGL 
• Discussion on Discord about Camera COMP in raymarching
• SDFs on Inigo Quilez site 
• SDF capsule math tutorial by Inigo Quilez himself
• SDF of a head by tdhooper
• My TOP trails tutorial 
• 3D Tube trails by atagen 

Oooff! That's it. Or is it? Did I mentioned something else? :)

Cheers,

Stas
