226 | Welcome to the svox documentation¶
175 |This is a PlenOctree volume rendering implementation as a PyTorch extension with CUDA acceleration.
176 |Note this only implements octree (or more generally N^3 tree) operations and differentiable volume rendering. It does not relate to NeRF training part of the project 177 | and does not involve a neural network.
178 |The code is available in this repo. 179 | This is part of the code release of
180 |
181 |
184 | PlenOctrees for Real Time Rendering of Neural Radiance Fields

189 | Website: https://alexyu.net/plenoctrees
187 | Source code (SVOX): https://github.com/sxyu/svox
188 | Install with pip install svox.
>>> import svox
191 | >>> tree = svox.N3Tree(data_dim=4)
192 | >>> print(tree)
193 | svox.N3Tree(N=2, data_dim=4, depth_limit=10; capacity:1/1 max_depth:0)
194 | >>> tree.to('cuda:0')
195 | data_dim is the size of data stored at each leaf.
Please see Reference for detailed per-method documentation and Quick Guide for a quick overview of features. 199 | This is the documentation of svox version: 0.2.32-dev.
