The Molecule Visualizer is a program to visualize molecules in a real-time 3D application. The user can load a molecule file from the Protein Data Bank with PDB format. The challenge when visualizing molecules is to find ways to improve the perception of the spatial structure. Especially large molecules are problematic. The methods that were chosen to tackle the perception problem are described in the "Functionality" section. A more detailed description can be found in the paper "Ambient Occlusion and Edge Cueing to Enhance Real Time Molecular Visualization" by Tarini et al. [1]. The implementation is based on the algorithms presented in that paper. The program was implemented as an assignment of the course "Visualization 2" at the Technical University of Vienna in the summer semester 2014.
