Not supported, was removed from the library.

Hey @tentone,

Currently I'm working on a project where this feature is needed and I'm considering contributing the implementation.

I you have any, would you mind sharing some of your experience or insights regarding this?

Was there a critical reason this was not implemented to begin with, or was it more a matter of time?

Hello

Feel free to work on the feature, i will be glad to help you merging the code into the project.

The feature was not needed initially thats why it was not implemented.

Hey @MarcusAndreasSvensson , I would like to know if you were able to implement classification.

Hey @srihari-bg.

I was indeed able to implement classification using the original Potree project as a base. This included also changing some data structure for handling individually controlling visibility of different classifications.

I was doing multiple things at the same time and the effort to isolate the different features didn't fit into my time frame unfortunately.

hey @MarcusAndreasSvensson That's great to hear, I would love to have a copy of your project where you have implemented the Classifications feature.

Thanks

I got some of the classification-related coloring working with potree-core by setting "material.newFormat = false" when material.pointColorType is PointColorType.CLASSIFICATION, and calling "material.updateShaderSource()" afterward. If I recall correctly this caused it to appear with default classification colors. The colors can be changed by modifying the "material.classification" object.

@asbjornlystrup Thank you for this workaround! For the time being, I will use that.
