Talk:WxNviz

Proposal for Google SoC 2010

To continue in wxNviz development which has been started in the frame of Google Summer of Code 2008.

Main goals:

1. To implement all missing features from TCL/TK nviz application and replace nviz by wxNviz in GRASS 7 (remove TCL/TK dependency)
   • Lighting
   • Decoration (labels, north arrow, scale bar, legend, fringe)
   • Querying (rasters, vectors, volumes)
   • Cutting planes, scaled difference
   • Animations
   • Scripting, including replacement for tool to generate images for dynamic surfaces
   • Point symbols sized and colored based on attributes
   • Make wxNviz working on MS Windows
   • Add more features here...
2. New features
   • Fog support (see [1], [2], [3])
   • Vertical labels (take from geonames.org point data): like in http://tev.fbk.eu/marmota/blog/?p=82
   • Add more features here...
3. Update CLI tool nviz_cmd
4. (optional) Design and implement text displaying and styling in OGSF library and it's front-end wxNVIZ. Solution should be user configurable (fonts, colors, effects etc.) and multilanguage friendly.
5. (optional) Design and implement user-provided symbol support in OGSF library and it's front-end wxNVIZ. Solution should support GRASS symbols and/or SVG symbols.
