Impulse is a new creative tool for choreographers to explore large-scale movement and spatial composition beyond the limits of traditional rehearsal. As a plug-in for Unreal Engine, Impulse leverages motion capture and real-time 3D technology to extend the dance studio into a flexible digital space where movement can be multiplied, rearranged, and refined with ease. The result is expanded opportunities for experimentation, a radically simplified MoCap workflow, and more fluid creative planning throughout the choreographic process.
