3D Projection Mapping in TouchDesigner
This TouchDesigner showcase project was published by Derivative in 2022.
Of the techniques available for projection mapping, 3D projection mapping is one of the more interesting and accurate options available. Instead of relying on drawing masks, 3D projection mapping uses a 3D model of the projection surface, a virtual camera and some math to calibrate the projection.
