'''wxNviz''' jest  rozszerzeniem [[wxGUI]] pozwalającym na realistyczne renderowanie multiple surfaces (danych rastrowych) w przestrzeni 3D z możliwością kolorowania tematycznego, nakładania danych wektorowych 2D na powierzchnie, przestrzennego wyświetlania danych wektorowych 3D oraz wizualizację danych volume (danych rastrowych 3D).

wxNviz jest rozszerzeniem wxGUI pozwalającym na realistyczne renderowanie multiple surfaces (danych rastrowych) w przestrzeni 3D z możliwością kolorowania tematycznego, nakładania danych wektorowych 2D na powierzchnie, przestrzennego wyświetlania danych wektorowych 3D oraz wizualizację danych volume (danych rastrowych 3D).

Rozwiązania problemów

  • Nic się nie renderuje:
Please note that with wxGTK port of wxPython (Linux systems), a problem might appear during wxNviz initialization (nothing is rendered at all) or when rendering vectors (bad order of rendering surfaces and vectors). If you encounter such problems, try to change a depth buffer number in wxGUI Menu > Settings > Preferences > Map Display > Advanced (possible numbers are 0, 16, 24, 32). It is currently not possible to automatically find out the right number which is working for your computer.

Znane problemy

  1. Lista otwartych i zamkniętych biletów
  2. Adding vector data crashes wxGUI on Mac
  3. Viewing height sometimes sets to 1 after switching to 2D and back to 3D View (or with the simultaneous 2D view - very nice feature) and even after View is reset, it keeps getting back at 1 each time the slider is touched
    Fixed in r46208
  4. Adding draw, draw current and clear button may be useful
  5. Thematic mapping is available in GRASS 7 only
  6. Display region in 3D does not change accordingly to display region in 2D in version <= 6.5
  7. Appearance:
    1.  I need to click View tab to get the arrow draw, same for the scale bar
    2. add legend > OK: nothing gets drawn in 3D but the legend shows up when I switch to 2D but when I clicked delete scalebar (which was not drawn), my surface disapeared but the legend showed up along with white and black background (which I assume was supposed to be transparent, because when I moved the legend the surface was under it - we already discussed this, it may be my problem, because it works for Michael).
  8. General
    1. when I go from 3D view to 2D and then back to 3D I lose most of my settings 
    2. similarly, when I add volume to Map layers I lose my view settings and the 3D view goes back to default
  9. Volumes:

  10. changing color to constant did not change the color of the isosurface
