“Before NVIDIA Instant NeRF, creating 3D scenes required specialized equipment, expertise, and lots of time and money. Now it just takes a few photos and a few minutes,” TIME writes in their release.
The 3D rendering tool was introduced at SIGGRAPH 2022, the world’s largest conference for computer graphics and interactive techniques.
At SIGGRAPH, NVIDIA researchers Thomas Müller, Alex Evans, Christoph Schied, and Alexander Keller submitted their paper, Instant Neural Graphics Primitives with a Multiresolution Hash Encoding. The innovative research quickly gained popularity, winning the SIGGRAPH 2022 Technical Papers Award.
Accumulating tens of thousands of downloads and achieving over 9,700 stars on the Instant NeRF GitHub page, developers and 3D content creators are embracing the ability to create stunning 3D scenes with the tool.
What is a NeRF?
Neural Radiance Fields (NeRF) are neural networks capable of generating 3D images or scenes from a set of 2D images. Using spatial location and volumetric rendering, the model uses the camera pose from the images to render the 3D space of the scene.
NeRFs are computationally intensive and historically required many hours for rendering. However, Instant NeRFs give users the power to render an image or scene quickly and accurately with a small number of images. You can generate a scene in seconds and the longer the model trains the more details of a scene are rendered.
To support developers adopting Instant NeRF, NVIDIA hosted an Instant NeRF Sweepstakes over the summer. The event encouraged contestants to explore their creative abilities while using InstantNeRF and the chance to win a GeForce RTX 3090. The sweepstakes reached over 2.7 million people on Twitter.
Since the code release, a large community of creators ranging from AI researchers to photographers have demonstrated their Instant NGP skills by making their own NeRFs.
“NeRF is a way to freeze a moment in time that is more immersive than a photograph or a video. It’s a way to recreate a moment – the whole moment. NeRF is the natural extension of photogrammetry and the evolution of modern photography,” said Michael Rubloff of Franc Lucent, an early explorer in NeRF technology.
“Museums are great exploration fields for interactive and immersive experiences. Volumetric scenes like this one can also directly contribute to historical heritage conservation, with a modern and immersive twist,” said Hugues Bruyère, partner and chief of innovation at the Montreal-based creative studio Dpt.
The community has taken NeRFs to another level by expressing themselves and their art through this new form of photography. Some have even found ways to make NeRFs impactful in how they work.
