Chuang et al. 2009 describes a method for color blending which preserves the original hue in blended regions. This probject contains a demo implementation of the hue-preserving color blending algorithm for front-to-back compositing. The application shows a side-by-side comparison of the reference implementation for hue preserving color blending and alpha compositing for a volumetric data set. With the goal of providing a realtime solution, the algorithm is implemented as an OpenGL shader to enable GPU accelerated rendering. Values for Colors, the seperation function and orientation can be changed and are updated in realtime without any visible delay. Volume orientation is computed directly in the shader during texture lookup, which means there is no copy or moving overhead as there would be with pre-rotated volumes.
Sourcecode documentation can be found here.
This application uses QT5 for the user interface and rendering is done using OpenGL/GLSL 4.3 Core Profile.
To run the application, navigate to bin and run Visualisierung.exe.
