Tr3: 3-D surface triangulation

1. Introduction

Tr3 is a home-grown programme for triangulating 3-D surfaces between serial-section contours. It takes a .tr3 plain-text model-definition file (as produced by Fie) as input and produces a VRML model file (.wrl) and a finite-element model file for use by SAP IV.

Tr3 is implemented in Fortran. It was originally developed under VMS, and later under Unix for Alpha, and is currently being developed under Debian GNU/Linux for Alpha and Intel, and under (alas) Microsoft Windows; the binaries are available for downloading below. It can be used for any purpose as long as I am informed of its use. So far there is no documentation beyond what you're looking at.

2. Installation

2.1 Installation under MS Windows 95/98/NT

Either download the Tr3 executable for 32-bit Windows (about 1.6 Mbytes) or (if your computer is part of the McGill BME network) create a shortcut to the executable on probeShare. Follow the general instructions for installation of Dip software.

If you are using a copy of Tr3 installed on your local hard disk, then you must also provide the Glib library and two associated libraries. Download the following DLL files into the same directory that tr3.exe is in:

• libglib-2.0-0.dll
• libintl-1.dll
• iconv.dll

Tr3 also uses a statically linked copy of the GLE Tubing and Extrusion Library by Linas Vepstas.

2.2 Installation under GNU/Linux

If your computer is part of the McGill BME network, create a symbolic link (ln -s) to the executable on probeShare. Otherwise download the Tr3 executable from here and do chmod u+x tr3 to make it executable.

• i386 binary (ask me)
• amd64 binary

Follow the general instructions for installation of Dip software.

3. Usage tips

3.1 Logging

Tr3 creates a log file called tr3_log.tmp in your home directory. As Tr3 is running, certain information is recorded in that file. It may be useful for debugging.
