Completion of wxGUI Nviz extension for 3D data visualization in GRASS GIS
Anna Kratochvilova
Abstract
This project continues in the development of GRASS GIS 3D visualizaton tool wxNviz based on wxPython and underlying OGSF library. The goal is to add missing functionality so that wxNviz's predecessor written in Tcl/Tk could be replaced by completed wxNviz in GRASS 7. The plan is to add missing features like animations or cutting planes and additionally implement better view control.
Additional Information
wxNviz is a one of the wxGUI extensions. It enables visualization of
multiple surfaces (raster data) in 3D space, volume data (3D raster
data), overlaying 2D vector data over surfaces and displaying 3D
vector data. wxNviz uses OGSF and Nviz library as an interface for
OpenGL. Completion of wxNviz is essential for GRASS 7 which can be
released only without dependency on Tcl/Tk. This project picks up on
wxNviz development within Google Summer of Code 2008 and 2010 and it
should make wxNviz fully functional.
