Z-Vis is a flow visualization utility, that has been developed during the 05/06 winter term for the Labor Uebung in Volume Visualisation. The team members in this project are Stefan Mueller and Adam Barclay.
Detailed Description
Z-Vis utilizes different methodologies to visualize flow data specified by geometry and raw data files. The data is presented in multiple ways including arrow plots, stream lines, Glyph based stream lines, and data based texture. Stream lines are implemented based on the techniques described by Jobard and Lefer, 1997. As of its current implementation, Z-Vis enables the following feature set:
- Uniform arrow plots
- Data weighted non-uniform arrow plots
- Interactive grid size selection and realtime update
- Support for the following stream line visualization techniques:
- Interactive sampling distance settings
- Interactive selection of integration mehod: Euler or Rung-Kutte of 2nd order
- Interactive integration step size selection
- Visual comparison of results between Euler and Runge-Kutte
- Glyph-based streamlines
- Streamline based texture generation
- Image Composition
- Pressure visualization using color inerpolated background with interactive transfer function
Software Environment
Z-Vis has been developed from the ground up using OpenGL and Glut. The user interface has been developed using the OpenGL based Glui SDK wich can be found here.
