Optimisation of a Graph Visualization Tool Vizz3D

Vizz3D is really a graph visualization tool developed at Växjö University. It’s utilized to visualize different factors of software systems in 3D, depending on the static analysis of source code. It could optionally use Java3D or OpenGL like a graphics library To be able to visualize huge 3D structures performance is essential. This originates from the truth that the structures need to be redrawn without delay whenever a user interacts using the system. If there were clearly a delay the consumer would loose the cognitive orientation because his interaction and also the feedback wouldn’t fit. Vizz3D wasn’t competent to run huge visualizations fast enough, therefore careful optimisation was essential….
