Therion is a complete platform which processes survey data and
|
|
generates maps or 3D models of caves. This suite may be useful for
|
|
professional or amateur cavers and researchers in geology or
|
|
speleology fields.
|
|
|
|
The package includes the following components:
|
|
- therion: the basic executable program that works as a command-line
|
|
compiler and processes input files, which are - including 2D maps -
|
|
in text format, to create files with 2D maps or 3D model. 2D maps
|
|
can be generated in PDF or SVG formats or other formats handled by
|
|
GIS platforms (DXF, ESRI, KML) or Aven (Survex format). 3D models
|
|
can be generated in the native format (handled by the component
|
|
Loch) or other formats (Compass, 3DMF, VRML, Survex, ecc.) handled
|
|
by appropriate viewers.
|
|
- xtherion: the executable program that launches the GUI (Graphical
|
|
User Interface). Xtherion works as text editor, map editor, and
|
|
compiler (instead of therion). This component is not essential:
|
|
output files can be generated by therion preparing the input files
|
|
with external programs as text or maps editors.
|
|
- Loch: a 3D model viewer that supports high-resolution rendering to
|
|
file and stereo view using 3D-glasses. This component is not
|
|
essential: output 3D models can be displayed with other external
|
|
viewers.
|
|
- thbook.pdf: the Therion Book, it contains the documentation to use
|
|
Therion, generated with pdfTEX during the build process. It will be
|
|
installed in /usr/doc/therion-[VERSION]. This component is not
|
|
essential: a copy of the book (in basic size format) is also
|
|
available in the project homepage.
|
|
|
|
The build of the optional components is enabled by default. You can
|
|
exclude one or more of them by passing to the script the respective
|
|
environment variables:
|
|
|
|
- LOCH=no This disables the build of the native 3D viewer Loch. In
|
|
this case wxWidgets and VTK are not required.
|
|
- GUI=no This disables the build of Xtherion.
|
|
- BOOK=no This disables the build of thbook.pdf.
|
|
|
|
WARNINGS
|
|
|
|
Note that the platform works only with some standards, interpreters or
|
|
programs (like METAPOST, TEX, tcl/tk, ImageMagick, ecc.) that are
|
|
available in a full installation of Slackware, and some extensions of
|
|
these (like LCDF Typetools, Bwidget, and tkImg) that are available in
|
|
Slackbuilds.org. Without these dependencies Therion fails during the
|
|
package build (almost) or in runtime for some features (e.g. tkImg,
|
|
that is not detected by the build process).
|
|
|
|
Since version 6.1.7, Therion no longer includes an internal {fmt}
|
|
library, so this library is a required dependency. In Slackware 15.0,
|
|
this library must be installed by the slackbuild available in
|
|
Slackbuilds.org whereas in Slackware current it must be installed
|
|
from the package released with the official current.
|
|
|
|
Since version 6.1.8, the build of LOCH fails if wxGTK3 is installed
|
|
instead of wxWidgets 3.2.2.1, so wxWidgets is strictly required. If
|
|
both wxGTK3 and wxWidgets are installed, the build process will use
|
|
wxWidgets, so these libraries can coexist. Other libraries based on
|
|
wxWidgets (like wxPython3 or wxPython4 for example) are not tested.
|
|
|
|
After the installation, a full and extended integrated behavior,
|
|
optimized with the custom configuration, requires to set or uncomment
|
|
appropriate values in the initialization files in /etc/therion.
|
|
|
|
Sample data can be downloaded from the project homepage. They can be
|
|
used to practice about Therion.
