TRELLIS.2: Microsoft’s 4B-Parameter Image-to-3D Generator Completes 3D Models in 3 Seconds
25 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 …
Free4D 4D Scene Generation: Revolutionizing Dynamic Content Creation with Single-Image AI
6 months ago 高效码农Free4D: Generating High-Quality 4D Scenes from a Single Image Without Fine-Tuning In the realms of film special effects, game development, and augmented reality (AR), creating dynamic 3D environments (commonly called 4D scenes) has long been a technical hurdle. Traditional methods either require massive training datasets or complex fine-tuning processes, making high-quality content creation slow and resource-intensive. Now, researchers from Huazhong University of Science and Technology and Nanyang Technological University have introduced Free4D – a framework that generates photorealistic 4D scenes from just a single image, with zero model fine-tuning required. This article breaks down the core technology, advantages, and real-world …
