1 Formatting of Matlab Text Files
The text files used in the Matlab GUI application specify 152 morphological traits of a wolf spider.
The parameters range anywhere from color specifications to length, width or scaling factors
for individual segments of the spider morphology. See 'spider.txt' for
example of a formatted file. The order of the parameters specified in the text files matters since
each data point is copied into a vector and passed in as an argument to the OpenGL/Visual C++
program. Therefore, there must always be 152 parameters in the same order as specified in
the 'spider.txt' file. Each line of input in these files must also be as follows:
<parameter name> <parameter value>
The <parameter value> must be numerical and contain no spaces afterward. However, note
the space that exists between the <parameter name> and <parameter value>. Blank
lines and commented lines (i.e., lines beginning with '%') are allowed and skipped by the program.
Variables specified after the 152nd one are ignored by the program.
2 Development of MEX-files
For this project, the following configurations were used during development:
Microsoft Visual C/C++ version 6.0
Glut library version 3.7.6
To build a MEX-file using Microsoft Visual C++, refer to
To execute the MEX-file under Matlab, the libraries used for rendering the spider need to be present.
This requires that the glut library be downloaded and installed as well. Precompiled versions
of the library can be found at
Once the appropriate libraries are installed, the command 'mex -setup' needs to be ran from
the Matlab prompt to ensure the system recognizes the appropriate compiler and links in the
appropriate libraries (i.e. select the 'Microsoft Visual C/C++ compiler' when prompted).
These setup instructions only need to be done once on a system to ensure that all
mex files run properly in the future.
For further information on mex file setup, please refer to
documentation of MEX-files.
