Variance Reduction on the Camera Axis: Multi-View Score Distillation for 3D

Marian Lupascu, Mihai Sorin Stupariu, Ionut Mironica

Score distillation turns a pretrained 2D diffusion model into a 3D generator, but the per-step gradient is estimated from a single randomly chosen view: it is high-variance and blind to global shape consistency. Prior work addresses this by retraining the diffusion prior on multi…Read more
