The project

One workspace for building and calibrating the show.

Projection Mapper combines a live Butterchurn music visualizer with tools for images, video, corner pinning, grid warping, and polygon masks.

Build the composition in the controller, then open a clean synchronized projector window for the final output. The workflow is made for stages, installations, storefronts, models, and workshop experiments.
