Download the MT Libraries

Language and platforms

The code of the MT system is written in ANSI C++. It has been tested under the Unix environment on PCs (Linux operating system, GNU g++ compiler) and on a Silicon Graphics Indigo2.

License

The code of the MT libraries is distributed under the GNU General Public License.

Organization of code

The MT directory is organized as follows:

                            MT
                             |
        +-------+-----+------+------+-----+----+
        |       |     |      |      |     |    |
     include   src   demo   data   doc   lib  util
        |       |     
  +-----+       +-----+
  |     |       |     |
 krnl  ext     krnl  ext

include: header files for the MT system (kernel and extension).
src: source code for the MT system (kernel and extension).
demo: a few programs demonstrating applications of the MT; more programs will be added in the future.
data: files containing some MTs and related features (tile errors, vertex normals).
doc: documentation (these html pages). The entry point is file index.html.
lib: shared libraries resulting from compiling the kernel and the extension of the system.
util: some utility programs.

Each subdirectory of the MT package contains a file readme.txt explaining its contents.

The contents of the package are described in details here.

Instructions for downloading

You can download separately:

The MT system, demos, documentation, utilities (directories include, src, demo, doc, lib, util).
The pre-built MTs (directory data).

For the moment, the system is avaliable just for Unix-like platforms.

Downloading Part 1

Download the file:
mt.tar.gz (version 1.1)
mt-1.2.zip (version 1.2)
mt.net.zip (version 1.2 for dotnet)

The following instructions refer to the current version (for old version use the old file name).

Uncompress and unpack it:

gzip -d mt_1.2.tar.gz
tar xvf mt_1.2.tar

This will create directory MT under the current directory, and all its subdirectories and their contents, except for subdirectory MT/data which is left empty. Directory MT/lib is also empty and will contain the binaries after compilation. The space required is about 6Mb.

Downloading Part 2

Download the file mtdata.tar.gz.

Uncompress and unpack it:

place the file mtdata.tar.gz under the directory where you have placed the MT
gzip -d mtdata.tar.gz
tar xvf mtdata.tar

This will give the contents of subdirectory MT/data. The space required is about 55Mb.

If you want to get just the MTs nedded to run the demos, you can download separately the files:

bunny.mtf.gz, bunny.err.gz, bunny.nrm.gz: an MT representing the surface of a solid object, needed for demo1 (about 10Mb).
marcy128.mtf.gz, marcy128.err.gz: an MT representing a terrain, needed for demo2 (about 3.5Mb).

and place them in subdirectory MT/data.

Instructions for installation

Installation of the MT libraries

Make the libraries by compiling the source files:

cd to directory MT/src/krnl.
check that the compiler and options contained in the makefile match the ones of your system; edit makefile if necessary (you may have to change the macros related to "Flags" and "Compiler", see comments in makefile)
make libMT.so (the shared library will be placed in directory MT/lib).
Repeat the operations above in directory MT/src/ext for building the shared library libMText.so

Add directory MT/lib to your LD_LIBRARY_PATH by editing file .tcshrc in your home directory:

If such file does not contain a line starting with setenv LD_LIBRARY_PATH, then add the line:
where mt_path is the absoulte path to the MT directory on your system.
Otherwise, add :mt_path/MT/lib to the list of directories already present after setenv LD_LIBRARY_PATH (where mt_path is as above).

The new setting will hold for all shells created after the modification to file .tcshrc.

Installation of the demos

Our demos need the graphic libraries OpenGL (or Mesa) and Glut in order to run.
You may need to install these libraries on your system before installing the MT demos.

cd to directory MT/demo
check that the compiler, options, and library paths contained in the makefile match the ones of your system; edit makefile if necessary (you may have to change the macros related to "Flags", "Compiler" and "Graphic Libraries", see comments in makefile)
make demo1
make demo2

To check that everything works, try to run the demos. See the instructions for demo1 and demo2.

Installation of the utilities

cd to directory MT/util
check that the compiler, options, and library paths contained in the makefile match the ones of your system; edit makefile if necessary (you may have to change the macros related to "Flags" and "Compiler", see comments in makefile)
make

MT Building Programs for version 1.2 are not yet ready!! (but the MT files build with version 1.1 are good also to be used with version 1.2)

Download the MT Building Programs

The distribution policy of programs for MT construction depends on the specific program: some of them are distributed in source code, while some others are distributed just as compiled binaries. The distribution policy of each program is specified below.

Instructions for downloading

Each program for MT construction can be downloaded separately. The current distribution includes the following programs:

Program MT Delaunay (construction of MTs for terrains). See documentation.
This program is distributed under the GNU General Public License. Download the file delaunay.tar.gz.
The code is written in ANSI C++. It has been tested under the Unix environment on PCs (Linux operating system, GNU g++ compiler) and on a Silicon Graphics Indigo2. Space requirements: about 4.5Mb.
Program MT Jade (construction of MTs for surfaces in space). See documentation.
This program is distributed just as an executable file using the shared libraries libMT.so and libMText.so of the MT system (compiled for Linux and IRIX). Download the file mtjade.tar.gz.
The code is written in ANSI C. It has been tested under the Unix environment on PCs (Linux operating system, GNU g++ compiler) and on a Silicon Graphics Indigo2. Space requirements: about 6Mb.

For uncompressing and unpacking, proceed as follows (where xxxx.tar.gz denotes the file you have downloaded):

gzip -d xxxx.tar.gz
cd to the directory where you have placed the MT directory
tar xvf xxxx.tar

This operation will give a directory XXXX containing all the files, where XXXX depends on the program you have downloaded.

Instructions for installation

If your system is Linux or IRIX, you can try using the pre-compiled executables.

Otherwise, if the program you have downloaded is distributed together with its source files, you have to make the program by compiling the source files:

cd to the directory XXXX of the specific program.
check that the compiler and options contained in the makefile match the ones of your system; edit makefile if necessary.
Warning: the distributed version of makefile assumes that the MT directory is ../../MT; if this is not the case on your machine, edit the line defining variable MT_DIR.
make.
