[GRASS-dev] TclTk question for Windows

GRASS GIS GRASS GIS developer

Below is a query from Paul Shapley about NVIZ and TclTk in Windows.

Is TclTk a separate installation for Windows folks or is it bundled with GRASS? If the latter, what version is bundled? I’m using TclTk 8.5.7 and it works fine. I’ve heard that 8.6 doesn’t work, but maybe that is only a Mac problem.

Hello Michael,

Just checked with an older version of Grass (6.4.0RC5 on Mac OSX with TclTk/Wish) and the same data displays at full (very detailed) resolution. Just wondering, does the windows version need TclTk installed separately?. I’m using the highest possible display resolution on 6.4.0RC5 on mac and 6.4.2RC2 on windows (same settings but low resolution is all i can get on windows). Setting ‘1’ highest res does not work for me in the latest release.

Anyway, seems the solution may be to revert to 6.4.0.

A couple things might help.

Under the visualize raster menu, you can change the display resolution.

But this can only display as fine as the underlying raster. If your grid cells are 1x1 km, that is the finest resolution you will see. You can increase your raster resolution through interpolation. This does not provide better data but can give you a ‘smoother’ view of your existing data.

I’m still having the resolution issue with NVIZ (TclTk) in the 6.4.2 release (recently upgraded). I’m not sure why the resolution is so course. Can anyone help! i’m using a 5m DEM and require high detail. Should i go back to 6.3.0 or use wxNVIZ?. I would rather something stable.

The improvements to wxNVIZ in trunk in the past 6 months have been so great that I’m tempted to suggest that we take it out of the GRASS 6.4.2 release. The version there is highly experimental and has quite limited functionality, whereas the TclTk version works well.

What do you think?

Hi,

2011/11/4 Paul Shapley <p.shapley@gmail.commailto:[p.shapley@gmail.com](mailto:p.shapley@gmail.com)>:

I’m using GRASS 6.4.2RC1-1 but cannot get a high resolution from an input

OSGeo4W? Than I suggest GRASS 6.4.2RC1-2.

dem/raster surface that i’ve been using with previous versions of Grass.
NVIZ will display the raster okay but will not allow a high res render. I
understand?NVIZ is in transition to python?but which Grass version (windows
installer) does NVIZ work fully.

Do you mean wxNviz [1]? GRASS 6 contains quite old version of wxNviz
(Google Summer of Code 2008/2010), improved version of wxNviz (Google
Summer of Code 2011 [2]) is available in GRASS 7 [3] or you can try
OSGeo4W package grass70-dev.
