It's a CUDA accelerated toolkit for storing and tracing volume data.<p>In my opinion, this one is pretty pointless because everyone who uses Nerf or similar technology in a game or end user product will need AMD and Intel GPU support, so CUDA is a no-go. And researchers can just copy a 200 line PyTorch model of they want to build a customized Nerf. Plus if you do that, you get the production export to onnx for free.<p>In short, I can't imagine any case where using a CUDA-specific closed source library would be superior to using readily available PyTorch scripts.
