3d-meshes

The author presents a method to create anamorphic sculptures by optimizing 3D meshes using gradient descent and differentiable rendering, demonstrated with a pig silhouette formed from car, pig, and pigeon meshes.

PhysiFormer uses coordinate-space diffusion to generate physically-plausible 3D object motions without explicit inductive biases, enabling efficient multi-object reasoning and generalization to complex materials and geometries.
