Description

GPU (integrated / discrete) support for NN search, DBSCAN and connected components. Potentially faster on CPU.

Use v2023.x since v2024 onwards does not support macOS.

Potentially faster:

  • nearest neighbor search: Compare nanoflann vs oneDAL-kNN
  • DBSCAN
  • connected components

Contributor guide

Research direction
Investigate how to integrate the oneDAL library into Open3D's build system (CMake) and replace or complement existing implementations for nearest neighbor search (nanoflann), DBSCAN, and connected components with oneDAL's GPU accelerated versions. Compare performance and ensure compatibility with Open3D's data structures.
