Instant NGP is an NVIDIA-developed framework for near-instant training of neural graphics primitives on a single GPU for various 3D and image synthesis tasks.

Instant NGP (Neural Graphics Primitives) is a cutting-edge framework by NVIDIA that enables rapid training of neural networks to represent complex 3D scenes and images. It leverages a multiresolution hash encoding to achieve near-instant results on a single GPU, making it highly efficient for tasks like generating gigapixel images, learning signed distance functions (SDFs), and implementing Neural Radiance Fields (NeRF). This technology significantly accelerates the process of creating and manipulating neural representations of visual data.
