DistoX and PocketTopo with Therion
by Bruce Mutton 13 Apr '10

13 Apr '10

Hi there I have a Disto arriving hopefully in a few days, and looking ahead I've been tentatively trialling PocketTopo on my PC. I suspect therein lies my first problem. Perhaps it only has limited functionality on PC's? I can manually enter data, but I can not seem to draw passage outline. The Export Therion format does not seem to produce data in a format similar to what Therion normally accepts - after the data it produces some form of co-ords separated into plan and elevation partitions. Most of the survey stations are converted to 10 digit numbers and all of the keywords are in capitals. Much of the file content could be made Therion compatible relatively easily using a text editor, but surely this is not what is intended? Obviously there is something significant here that I am missing. Have searched about but have not found the solution yet. Does anyone have a small dataset that demonstrates the interaction between PocketTopo and Therion? Bruce

version 5.2.8 uploaded to Debian
by Wookey 01 Oct '09

01 Oct '09

I uploaded a 5.2.8-1 therion package to Debian last night. Feedback/bugs very welcome. Known issues: 1) texturing on loch has been turned off in order to let it run at all on Intel graphics cards. 2) The wiki snapshot is rather old (same as for 0.5.1 release) - can someone furnish me a new one? 3) My therion svn is broken so it's not checked in yet.

seperate layers for surface and sketch images
by Bruce Mutton 15 Sep '09

15 Sep '09

Hi again Getting back to the task of including our existing paper maps in our Therion datasets. We have a large cave, with the existing plans comprising more than 5 overlapping sheets, representing differing regions and levels of the cave. Is any progress planned on separating the sketches from the surface layer in pdf outputs? If so I'd like to put in a request for each sketch to have it's own unique layer, and to support the transparency feature already implemented for passages and the surface. Are there any issues related to this (other than large run durations and file sizes)? Bruce

Transparent map-images
by Bruce Mutton 08 Jul '09

08 Jul '09

Hi All Michael and I are putting some large scanned map-images on our therion pdf plots, but near the point where they overlap, one always overwrites the other. We'd rather they be transparent so one map-image can be seen through the other. Will it help if I can figure out how to make the white background of the original scans transparent? Does anyone have any tips for making the white area of a jpg or pdf image transparent? I have access to Adobe Elements, but I'm not very good with it, and although there are instructions for doing this I didn't have much luck comprehending what was required. Regards Bruce

Loch Makefile
by Martin Luethi 14 Jun '09

14 Jun '09

Hi There are some weird settings in the Loch Makefile for the VTK variables. It seems that VTKPATH is used to mean VTKINCLUDEPATH, but also for VTKLIBPATH, which causes problems. Here is a better version (only for target Debian) Best, Martin # PLATFORM DEBIAN CXX = c++ CC = gcc POBJECTS = lxR2P.o VTKPATH = /usr/local VTKINCLUDEPATH = $(VTKPATH)/include/vtk-5.2 VTKLIBPATH = $(VTKPATH)/lib/vtk-5.2 VTKLIBS = -lvtkHybrid -lvtkImaging -lvtkIO -lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype CXXPFLAGS = -DLXLINUX $(shell wx-config --cxxflags) -Wno-deprecated $(shell freetype-config --cflags) -I$(VTKINCLUDEPATH) CCPFLAGS = -DLXLINUX $(shell wx-config --cflags) LXLIBDIR = linux PLIBS = $(shell wx-config --libs --gl-libs) -L$(VTKLIBPATH) $(VTKLIBS) -lGLU -lpthread -lz LXPLATFORM = LINUX

How to compile without Loch
by Bill Gee 10 Jun '09

10 Jun '09

Hello everyone - I have been struggling for two days trying to get Therion 5.2 (stable) to compile on my brand new CentOS 5.3 system. The dependencies are killing me! CentOS repositories do not include any VTK packages, so I had to build VTK 5.4 from source. That brought its own set of dependencies - I had to compile CMake from source before I could compile VTK! Sheesh!!! This is ridiculous ... Anyhow, the message I am stuck on now comes from "make install" of Therion. It appears to be related to some missing piece of VTK. Can anyone shed some light on how I deal with this? ============== c++ -o loch -Wall lxR2P.o lxTR.o lxOGLFT.o lxSetup.o lxRender.o lxWX.o lxImgIO.o lxLRUD.o lxFile.o lxData.o lxMath.o lxSView.o lxSScene.o lxGUI.o lxGLCo.o lxGLCs.o lxOptDlg.o lxAboutDlg.o img.o -lwx_gtk2u_gl-2.8 -pthread -lwx_gtk2u_richtex t-2.8 -lwx_gtk2u_aui-2.8 -lwx_gtk2u_xrc-2.8 -lwx_gtk2u_qa-2.8 -lwx_gtk2u_html-2. lwx_gtk2u_adv-2.8 -lwx_gtk2u_core-2.8 -lwx_baseu_xml-2.8 -lwx_baseu_net-2.8 - lwx_baseu-2.8 -L/usr/include/vtk-5.0/lib/vtk -lvtkHybrid -lvtkImaging -lvtkIO - lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype -lpthread -lz -s /usr/bin/ld: cannot find -lvtkHybrid collect2: ld returned 1 exit status make[1]: *** [loch] Error 1 make[1]: Leaving directory `/Installs/therion/loch' make: *** [loch/loch] Error 2 =============== Searching the system for files like "vtkHybrid*" finds vtkHybrid.CMake in the source directory for VTK. I don't find anything else on the system. At the end Therion is not installed. I don't need Loch. Is there a directive for make to tell it to ignore Loch? Thanks - Bill Gee

therion 5.2.9
by Bruce Mutton 02 Jun '09

02 Jun '09

Hi Just tried out 5.2.9 and, while it worked fine, I noticed a few new things; 1. There's now a filter for surveys. What does it filter? Makes no change to my data and nothing in the Therion Book yet. 2. There are a few new warnings in 5.2.9 not present in 5.2.8; Warning: cannot open font map file psfonts.map, and Warning: the turningnumber algorithms do not agree. The current computed value is 0, but the 'connect-the-dots' algorithm returned -1 See the attached log files. Are these of concern? Or suggest something that I should be doing differently? 3. This is probably not a 5.2.9 thing, but does it suggest that my cave has nearly reached Therions ability to create the pdf? PDF statistics: 750 PDF objects out of 1000 (max. 8388607) 7 named destinations out of 1000 (max. 131072) 1967 words of extra memory for PDF output out of 10000 (max. 10000000) Ie 750 objects out of 1000 which maybe signifies three quarters of capacity? The part of the cave processed is about 2% of current surveyed length, and the survey and map structure will be getting much more complex before we are finished. Is there something we should be doing differently so as not to reach 'maximum capacity' before we finish our map? Regards Bruce
