D-Prism: Differentiable Primitives for Structured Dynamic Modeling - CVPR 2026 Intro Video

Capturing geometry and rigid motion for structured dynamic objects is challenging. Existing methods rely on unstructured representations, failing to jointly model geometry and articulated motion. We propose D-Prism. It is the first framework for high-fidelity structured dynamic modeling. We extend differentiable primitives to the dynamic domain.

Key Features:
Geometry & Appearance: Bind 3DGS to primitive surfaces to leverage their respective strengths.
Precise Tracking: Use a deformation network to control primitive motion and match object movement.
Topology Management: Apply a novel adaptive control strategy to dynamically adjust primitive counts.

D-Prism excels at structured dynamic modeling. It provides both structured geometry and precise motion tracking.
