Flux3D.jl


Flux3D.jl is a 3D vision library, written completely in Julia. This package utilizes Flux.jl and Zygote.jl as its building blocks for training 3D vision models and for supporting differentiation. This package also have support of CUDA GPU acceleration with CUDA.jl.The primary motivation for this library is to provide:

  • Batched Data structure for 3D data like PointCloud, TriMesh and VoxelGrid for storing and computation.
  • Transforms and general utilities for processing 3D structures.
  • Metrics for defining loss objectives and predefined 3D models.
  • Easy access to loading and pre-processing standard 3D datasets.
  • Visualization utilities for PointCloud, TriMesh and VoxelGrid.
  • Inter-Conversion between different 3D structures.

Any suggestions, issues and pull requests are most welcome.
