Instant Neural Graphics Primitives with a Multiresolution Hash EncodingNeural gigapixel images Neural SDF NeRF Neural volume We demonstrate near-instant training of neural graphics primitives on a single GPU for multiple tasks. In gigapixel image we represent an image by a neural network. SDF learns a signed distance function in 3D space whose zero level-set represents a 2D surface. NeRF [Mildenhall et al. 2020] uses 2D images and their camera poses to reconstruct a
