Beautiful Point Cloud

This Python script allows you to convert your point cloud data into beautifully rendered 3D images using Mitsuba.

• The script creates a XML file describes a 3D scene in the format used by the Mitsuba renderer.
• Then proceeds to render this scene and save the result as a PNG file.
• If your data tensor contains multiple point clouds, the script will iterate over them and produce multiple renderings.

Currently, the script supports both .ply and .npy file formats.

This project is inspired by the amazing work done at Point Flow Renderer.

Everyone is welcome to use the project. If you have any enhancements or fixes, I encourage you to make a pull request.
