Project Canvox is a voxel-based Virtual Reality creativity tool created by Adobe Research. Its infinite 360-degree landscape, coupled with its ability to zoom in to manipulate the smallest of details, makes Canvox the ultimate playground for spatially-oriented designers. Within the tool, users are able to paint using three-dimensional voxels, enabling a structural accuracy not found within pixel-based VR painting tools like Google TiltBrush. Furthermore, Canvox removes the barrier faced in complex 3D modeling tool by placing users in a natural landscape. Rather than needing to transmit 3D design decisions through a complex 2D interface, users engage with 3D content in a 3D module, with a simple UI optimized for VR. Our ethnographic interviews and rigorous user studies investigated the optimal role of Canvox within a 2D-3D design production pipeline.
