Overview#

Pointrix is a powerful and easily extensible framework built around point cloud rendering, with the following core features:

  • The core of point cloud rendering supports various rendering functionalities and advanced operations, with all inputs returning gradients (point cloud properties, camera parameters).

  • The point cloud rendering core is modularized to maximize user interface openness, allowing extensive customization.

  • All components are modular to simplify researchers’ steps in secondary development as much as possible.

  • Supports current mainstream Gaussian point cloud work.

The overall framework of Pointrix is illustrated in the diagram below:

Data Components#

  • Dataset Reader: Parses various types of data provided by developers into a unified data format.

  • Data Pipeline: Manages the flow of unified data format to the trainer.

Model Components#

  • Point Cloud Model: Computation graph component based on Gaussian point clouds.

  • Msplat Renderer: Core component of point cloud rendering. Supports various rendering techniques. All inputs return gradients (camera intrinsic and extrinsic parameters), and interfaces are modularized to the extent possible.

  • Camera Model: Computation graph component based on camera models.

Logging, Visualization, Configuration, Registration, and Hook Components#

  • Logger and GUI: Interact with all components, supporting logging and visualization of intermediate results generated throughout the process.

  • Hooks, Configuration, and Registry: Interact with all components, supporting developers in customizing workflows and configurations for all components.
