Capturing a 3D World with 2D images within a minute!

Amazing Outcome from Instant Neural Graphics Primitives with a Multiresolution Hash Encoding

Instant Neural Graphics performs almost instantly to reconstruct a 3D scene with multiple 2D images in different camera angles. Furthermore, it is one of the fastest NeRF technology, neural radiance fields

Interactive Tool

Customize your own dataset and use instant neural graphic to generate the 3D view! Try it out

Interactive tool for instant training and graphic rendering

The model estimates the depth and appearance of an object based on a partial view to reconstruct the scene, using the new input encoding method the model perform very much instantly!

Dataset Preparation

Taking a bunch of photos in different views of the scene or object and then apply it to the COLMAP library, feature extraction program.
