Single time value option in scalar field?

Post by pflani »

Hello!
My point cloud .asc file has a time column in milliseconds (16311323330689, ..., 1631132354754) that I have selected as a scalar field. However, the "SF display params" lists a single value of 1631132319744.00000000 (which is prior to the first time assignment in the .asc file). Any idea on why it shows a scalar field value prior to the data range? Why is only a single time displayed?
I would like to be able to use the slider bar to vary which points are displayed depending on the time gathered.
Thank you for your time!
Paul

Ah, sadly that's an accuracy issue due to the fact that internally CC uses 32 bits to store numbers (instead of 64 bits, to reduce the memory consumption).

It is properly handled with LAS files, but not with ASCII files that are too generic...
