TRELLIS.2: Microsoft’s 4B-Parameter Image-to-3D Generator Completes 3D Models in 3 Seconds

TRELLIS.2 Deep Dive: How a 4B-Parameter Model is Revolutionizing Image-to-3D Generation Have you ever wondered how quickly a simple 2D image can be transformed into a detailed, photorealistic 3D model with full materials? The latest answer from Microsoft Research is astonishing: as fast as 3 seconds. Let’s explore the core technology behind this breakthrough. Executive Summary TRELLIS.2 is a large-scale 3D generative model with 4 billion parameters. Its core innovation is a novel “field-free” sparse voxel structure called O-Voxel. This technology overcomes the limitations of traditional iso-surface fields (like SDF) in handling open surfaces and non-manifold geometry. It can generate …
