Hello all, Is anyone else having trouble accessing therion.speleo.sk? I'm working on a Fedora package for Therion and went to look up some information and received a 503 error. Hopefully it isn't anything significant! Best regards, Jonny

3D export from ParaView to MeshLab - data with coordinates
by Martin Sluka 10 Nov '15

There is another solution: Export VTK fgrom Loch in ASCII format. For that feature you should change one line in source lxData.cxx about line 615. w->SetFileTypeToBinary(); to w->SetFileTypeToASCII(); and recompile Loch. Thanks to Stacho m.s.

Updated Tutorial
by Footleg 03 Nov '15

03 Nov '15

I have just put an updated draft of my Therion Tutorial online (link on the Therion wiki), or click here: http://wscc.darkgem.com/footleg/therion/ I've completed lessons on area fills, and tackled the much more complex topic of how to structure your data for a project which is more than one scrap/survey trip. There are many ways to do this of course, but I have suggested one in the tutorial which should help people who do not already have a data model in mind. As always I welcome feedback and comments which will help me and others to improve and learn more. Footleg

3D export from ParaView to MeshLab - data with coordinates

It is solution of thickheaded man, not exactly I want to be. :) Paraview: 1. Open VTK file exported from Loch 2. use Filter Calculator: (coordsX-XXX000)*iHat+(coordsY-YYYY000)*jHat+coordsZ*kHat Replace XXX000 and YYYY000 with your big part of X and Y coordinates Press Apply 3. Save data VTK - ASCII 4. In plain text editor: Replace part (only numbers!!!): with part: 5. Open in ParaView and Export Scene as .x3d 6. Open file in MeshLab 7. Filters -> Quality Measure and Computations -> Compute Geometric Measures Result: Mesh Bounding Box Size 3.968994 5.500000 1.700012 Mesh Bounding Box Diag 6.992350 Mesh Volume is 13.290228 Mesh Surface is 55.864479 Thin shell barycenter 939.219910 1057.403076 927.209839 Center of Mass is 939.140137 1057.342285 927.172058 Inertia Tensor is : | 729.754761 -248.443680 -105.337669 | | -248.443680 500.675079 -451.711975 | | -105.337669 -451.711975 323.904358 | Principal axes are : | -0.276003 -0.636824 -0.719915 | | -0.770395 -0.301299 0.561881 | | 0.574729 -0.709700 0.407447 | axis momenta are : | -117.115318 710.396851 961.000488 |

Therion and 3D Therion is able to export 3D model in format .lox based on LRUD data, shape of walls in plan and passage height informations recently. If the map is drawn in correct way these models are quite good. To view the model one should use internal viewer of Therion named Loch. The Loch has feature to export model in the VTK format. And several softwares for manipulating with 3D data for example CloudCompare or Paraview are able to import this VTK format. CloudCompare is able to export next formats: BIN .bin CloudCompare own format ASCII .asc,.txt,.xyz,.neu,.pts ASCII point cloud file (X,Y,Z,etc.) LAS .las ASPRS lidar point clouds E57 .e57 ASTM E57 file format PCD .pcd Point Cloud Library format PLY .ply Stanford 3D geometry format (cloud or mesh) OBJ .obj Wavefront mesh VTK .vtk VTK file format (triangular mesh or cloud only) STL .stl STereoLithography file format (mesh) OFF .off Object File Format (mesh) FBX .fbx Autodesk (Filmbox) File Format DXF .dxf Autocad DXF format SHP .shp ESRI Shape file format RASTER .geotiff, etc. Common raster formats (GDAL) PV .pv Point cloud + scalar field PN .pn Point cloud + normals Sinusx .sx Sinusx curves ParaView is able to work with next formats: ParaView files VTK files Parallel (partitioned) VTK files VTK MultiBlock (MultiGroup, Hierarchical, Hierarchical Box) files Legacy VTK files Parallel (partitioned) legacy VTK files EnSight files EnSight Master Server files Exodus files BYU files XDMF files PLOT3D files SpyPlot CTH files HDF5 raw image data files DEM files VRML files PLY Polygonal files Protein Data Bank files XMol Molecule files Stereo Lithography files Gaussian Cube files Raw (binary) files AVS files Meta Image files Facet files PNG files SAF files LS-Dyna files So you may for example calculate surface and volume of cave - thanks to Filippo Gregori: 1) Export the lox file to vtk format 2) With Paraview software I opened the file vtk 3) Save the file as .x3d 4) Open the file x3d in Meshlab software 6) Apply the filter: Filters -> Quality measure and computation -> compute geometric Measures 7) Open log window: View -> Show Layer dialog 8) Read the lines Volume Mesh and Mesh Surface
