In a groundbreaking development, NVIDIA Research has unveiled its latest AI model, Neuralangelo. The innovative model utilizes neural networks to reconstruct 3D scenes and objects from 2D video clips. Like Michelangelo’s mastery in sculpting intricate and realistic visions from blocks of marble, Neuralangelo breathes life into static footage, transforming it into detailed 3D structures. This remarkable technology enables creative professionals in various fields to import lifelike virtual replicas into their design applications. From art and video game development to robotics and industrial digital twins, Neuralangelo is set to revolutionize how we create and interact with virtual objects.
Neuralangelo: Turning 2D into 3D
Neuralangelo surpasses previous methods of 3D reconstruction by excelling in translating complex textures from 2D videos to 3D assets. Whether it’s the fine details of roof shingles, panes of glass, or smooth marble, Neuralangelo’s high fidelity ensures developers and creative professionals can rapidly create realistic virtual objects for their projects using footage captured by smartphones.
Bringing Reality to the Digital World
Ming-Yu Liu, senior director of research and co-author of the paper, emphasizes the significant benefit Neuralangelo offers creators. This tool allows developers to import intricate objects, ranging from small statues to massive buildings, into virtual environments for video games or industrial digital twins. With Neuralangelo’s capabilities, the digital world can faithfully replicate the real world, blurring the lines between the physical and the virtual.

From Art to Architecture, Neuralangelo Does It All
Neuralangelo’s capabilities extend beyond reproducing famous sculptures or architectural marvels. The AI model can reconstruct both interior and exterior spaces. The detailed 3D model of the park at NVIDIA’s Bay Area campus clearly demonstrates this. This versatility opens doors for various applications, allowing architects, designers, and artists to bring their visions to life with incredible precision.
Advancements in AI Technology
Prior AI models for 3D scene reconstruction struggled to accurately capture repetitive texture patterns, homogenous colors, and strong color variations. However, Neuralangelo tackles this challenge by incorporating instant neural graphics primitives, the same technology behind NVIDIA Instant NeRF. This breakthrough algorithm enables the capture of finer details, revolutionizing the accuracy and realism of 3D reconstructions.
The Magic Behind Neuralangelo
Neuralangelo’s reconstruction process begins with a 2D video captured from different angles. Like an artist observing a subject from multiple viewpoints, the model selects frames that offer varied perspectives. Once the camera positions of each frame are determined, Neuralangelo’s AI generates an initial rough 3D representation, similar to a sculptor chiseling the subject’s shape. The model then optimizes the render to enhance details, akin to a sculptor meticulously refining their work. The final result is a highly detailed 3D object or scene ready for use in virtual reality applications.
NVIDIA Research at the Forefront of Computer Vision
Neuralangelo is among the impressive lineup of nearly 30 projects presented by NVIDIA Research at the Conference on Computer Vision and Pattern Recognition (CVPR), held from June 18-22 in Vancouver. These papers explore diverse topics, including pose estimation, 3D reconstruction, and video generation. Neuralangelo’s introduction at this prestigious conference highlights its potential to revolutionize the field of computer vision.
