Where 3D Generative Models Stand: Reading the 2026 Technical Map Through Lyra 2.0
The dominant paradigm in 3D generation in 2026 is video diffusion feeding feed-forward 3D reconstruction, and Lyra 2.0 is the flagship of that line. But three Best Papers at CVPR 2026 point at what comes next: SAM 3D brings foundation-model-scale object reconstruction, D4RT rebuilds dynamic 4D scenes in seconds from a unified transformer, and O-Voxel replaces Gaussians with structured latents. 3DGS still rules, but surface primitives are challenging it, and pixel-space diffusion is pushing back against latent space.
