WxNviz

Back to wxGUI page.

Accepted Google Summer of Code 2008 project

• http://lists.osgeo.org/pipermail/grass-dev/2008-February/035792.html

Roadmap / Progress

Done

• Initial cleaning underlying GRASS OpenGL gsurf OGSF Library
  • Doxygenization, code documentation
  • Eliminate fprintf(), changed to G_*_message(), G_warning(), G_fatal_error(), and G_debug()

wxGUI Nviz extension

• Integration with Layer Manager, (un)loading when map layer is (un)/checked
• Integration with Map Display, auto-rendering functional
• View settings (position, height, perspective, twist, z-exag), perspective can be changed by mouse wheel
• Surface settings (attributes, draw mode)
• Vector 2D lines

In progress

• Update OGSF Library documentation
• Experimental prototype of CLI version of NVIZ (just very simple functionality)

http://trac.osgeo.org/grass/browser/grass/trunk/visualization/nviz2/cmd

• Design experimental nvizlib used by CLI and wxPython NVIZ prototype

http://trac.osgeo.org/grass/browser/grass/trunk/lib/nviz

• Experimental prototype of NVIZ toolbox for wxGUI (based on NVIZ CLI functionality)

http://trac.osgeo.org/grass/browser/grass/trunk/gui/wxpython/nviz

http://trac.osgeo.org/grass/browser/grass/trunk/gui/wxpython/gui_modules/nviz.py

wxGUI Nviz extension

• Surface, mask, position (needed?)
• Vector 2D lines, settings
• Save data layers settings, update workspace definition

Nviz CLI

• To be updated (based on wxGUI Nviz functionality)
