Hi Enrico - I found a posting on stackexchange with this method. It is not what I used several years ago. What I did back then was much simpler ... if only I could remember it! It seems to me it was in the statistics section of the therion.log file. Someone once told me what goes first when you get old. I don't remember what that was. ======== Bill Gee On Thursday, January 27, 2022 7:52:57 AM CST Enrico Fratnik wrote:
Hi Bill,
normally I export the VTK model of the cave from LOCH then I open it with ParaView With ParaView I export the model in x3d format and I open it with MeshLab where I use the filter "Surface Reconstruction: Screened Poisson" with pre-clean option active After that with the filter "Compute Geometric Measures" you can retrieve the volume on the log view.
My big issue is which model is better to export with therion in order to obtain an acceptable volume: the one with "-wall-source splays" or with "-wall-source maps"?
Hope this helps
good caves to everyone

Hello everyone -
Several years ago I made a map of a small cave. Among the data that was calculated was an estimation of the volume of the cave. I need to find that information again, but it has so far eluded me. I thought it was in therion.log along with other statistics like length and bounding box dimensions, but now I do not find it there. The estimation was based on solids calculated from centerline and LRUD data.
I looked in thTMPDIR and found nothing useful. I also checked to see if it comes from Aven or Loch. Nothing there. I looked through a KML file and found nothing.
Can any of you point me in the right direction? Believe it or not, I need to testify in court early next week about this. It's a long story ...
Thanks! ======== Bill Gee
