About
-----
XTracer is a raytracer written in c and c++.

v0.7 served as my thesis project for the BSc of computer science at the
University of Piraeus. It was developed under the supervision of Prof. T.
Panayiotopoulos as part of the research work of the Knowledge Engineering Lab.

v1.1 was developed as part of my dissertation for the MSc of computer graphics 
programming at the University of Hull.

v1.2 is the current version. All external dependencies have been integrated.

Compilation / Installation
--------------------------
The source code is distributed along with a makefile configuration script for
unix based systems with a GNU toolchain installed. To view all the available

you can build the binary by typing: make. To install the binary in your system
type: make install. To uninstall type: make uninstall

For windows users, a visual studio 2010 solution is available in the ide
directory.
