TRELLIS.2: Microsoft’s 4B-Parameter Image-to-3D Generator Completes 3D Models in 3 Seconds
5 days ago 高效码农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 …
WorldGrow: Infinite 3D World Generation Revolutionized
1 months ago 高效码农WorldGrow: A Revolutionary Framework for Generating Infinite 3D Worlds Introduction: Why Do We Need Infinite 3D Worlds? Why is infinite 3D world generation technology so crucial, and what fundamental challenges do existing methods face? In fields like video games, virtual reality, film production, and autonomous driving simulation, constructing large-scale, continuous, and content-rich 3D environments has always been a significant challenge. Traditional methods either rely on manual modeling, which is time-consuming and labor-intensive, or use existing generation techniques that often underperform in scalability and consistency. More importantly, with the development of embodied AI and world models, we need infinitely expandable virtual …
