Tomography acquisition and reconstruction
Graphical User Interface (GUI)
gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL).
SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.
Compatible with Windows, Mac and Linux Operating Systems
gVirtualXRay has been successfully tested on the following platforms (compilers):
- MS Windows 7, MS Visual C++ 2013
- MS Windows 8, MS Visual C++ 2010
- GNU/Linux openSUSE 12.3 (x86_64), g++ 4.7
- Mac OS X 10.8, Apple LLVM 4.2
- Mac OS X 10.8, g++ 4.7
Procedural texturing for realistic rendering of the anatomy
Supports ‘old’ OpenGL implementation as well as modern OpenGL core profile.
