las 1.4 extended classifications

[jjrise]

this may be something I'm overlooking, but I'm having a tough time getting extended classifications to convert or view. These originate from a las 1.4 file initially saved in terrasolid. These are not "extra bytes" las 1.2 classifications (i.e. terrascan), but rather 64-255 user defined classifications.

Any help would be appreciated!

If they're just the normal 0-255 byte classification, take a look at the classification example: http://potree.org/potree/examples/classifications.html
Use setTreeScheme() as a template to define your own color scheme.

Hi Markus, I did notice this, however it seems my classifications from my input (las 1.4 extended classes) do not properly convert through PotreeConverter 1.7. I'm using the classification example with setTreeScheme(), which is working as expected, but those classes do not hold any points after conversion.

EDIT: I should mention that the points that originated in extended classes are not missing, but they are all in the Default class after conversion.

Can you send me an example las file?

@m-schuetz I gave permissions to your email. Let me know if that doesn't work for you.

@m-schuetz Checking in on this topic. I too have a las file with extended classes. They are all getting smooshed down into the first 31 classes.
