The Best Image-to-3D AI to date: Neuralangelo
The best Image/video to 3D AI so far!
Good morning fellow AI enthusiast! This week's iteration focuses on NVIDIA's most recent AI: Neuralangelo. Neuralangelo improves upon its predecessor Instant NGP that revolutionized the NeRF approach by taking it to work from hours to seconds with higher quality. Neuralangelo makes the results even more realistic.

2️⃣ The Best Image-to-3D AI to date: Neuralangelo
Neuralangelo is NVIDIA's latest breakthrough in image-to-3D AI. This new approach builds upon Instant NeRF, enhancing surface quality and providing highly realistic 3D scenes from simple images in just seconds.
Neuralangelo aims to overcome the limitations of its predecessor, Instant NeRF, such as the lack of detailed structures and a somewhat cartoonish appearance of the AI-generated 3D models.
The secret behind Neuralangelo's improvements lies in two key differences: using numerical gradients for computing higher-order derivatives, and adopting a coarse-to-fine optimization on the hash grids controlling levels of detail, which we dive into in the video.
This optimization process results in a smoother input for the 3D model reconstruction, allows more information to be blended, and creates a perfect balance between consistency and fine-grain details for a realistic outcome.
The quality of Neuralangelo's 3D models is truly astounding, but the AI does face challenges with highly reflective scenes. Nonetheless, its potential real-world applications are vast and exciting!
