Clarification on Modifying `PointCloudOctree` Material Parameters and Point Colors

I am looking for guidance on how to dynamically modify the material parameters of PointCloudOctree in Potree, specifically size and color. I want to know if there are existing methods or approaches to:

1. Modify Material Parameters:

   • Change the point size and color properties of PointCloudOctree at runtime.
   • Apply these changes and see them reflected immediately without reloading the point cloud.

2. Adjust Point Colors within a Bounding Box:

   • Modify the color of points that fall within a specific 3D bounding box (bbox).
   • Update the colors of points dynamically based on user-defined regions or interactions.

Current Understanding:

I am unsure if these capabilities are already implemented or if there are specific APIs or methods available within Potree to achieve this functionality. If these features are supported, could you please provide detailed instructions or examples on how to use them?

Additional Information:

If such features are not yet available, could you provide guidance on how they might be implemented or if there are any plans to support these functionalities in the future?

Thank you for your assistance!
