THE DEMONSTRATION

A real-time volumetric performance system where music becomes an interface for world-making. Each musical gesture—beat, note, modulation—triggers a corresponding volumetric transformation.LIVE RENDER

THE EXPERIENCE

A synesthetic experience where remixing music equals remixing reality. A simple bassline may ripple through volumetric space, while a chord shift transforms a photoreal room into a surreal dreamscape.

Built upon a custom 4D Gaussian pipeline and interactive RealityFX system, performers spatially 'play' volumetric worlds as though they were musical instruments.

WHY IT MATTERS

Volumography as a performative medium, not static capture
RealityFX: the first real-time volumetric effects layer for Gaussian media
Remixing music equals remixing reality

THE VISION

All-at-Once proposes a new grammar for live volumetric performance—one that is poetic, participatory, and technically groundbreaking.

Next-generation concerts and theater
XR experiences where sound and vision merge
Living, generative stages of performance
