A TouchDesigner project that extends the GLSL Vertex Displacement shader into an animated particle system driven by texture feedback and procedural motion.
This work was reposted by the official TouchDesigner Instagram account.
The system uses the same GLSL MAT from the GLSL Vertex Displacement project. The sphere geometry is converted into a particle system via a Convert SOP, replacing solid geometry with individual points that the shader displaces.
Before reaching the shader, the source texture passes through a switchable effects module inside container_fx. The module includes a feedback loop, a radial blur, and a light tunnel effect. Because the feedback loop feeds the texture's previous state back into itself, the texture's history continuously shapes the particle positions.
An LFO drives the dispScale uniform, creating a pulsing animation without keyframes. A second feedback loop on the final rendered output adds temporal blurring and visual echoes.
Open the .toe file in TouchDesigner. The animation runs automatically. Swap the source image using the Movie File In TOP inside media_input. Switch between pre-processing effects inside the container_fx component.
