Volumetric Ray Marching – TouchDesigner Tutorial 15

I’m super excited to share two components with you: ‘VolumetricGeo,’ which runs volumetric ray marching to render 3D textures as volumes, and ‘soptoTexture3D,’ which allows you to convert any SOP or instances of SOPs into 3D textures, and then render them with ‘VolumetricGeo.’

The project file and components are available exclusively on my Patreon for patrons only.

I highly recommend reading Ryan Brucks’ blog if you’d like to learn more about volumetric ray marching:

Also, be sure to watch Vincent Houze’s 3-hour talk on GLSL in TouchDesigner, where he introduces 3D texture rendering:

Another great recommendation is to check out the T3D Toolkit by Josef Pelz on his Patreon page, which is extremely useful for creating volumes:
