[GRASS-dev] New OpenGL options to test for native Mac and Win NVIZ

[William Kyngesburye]

I brought home the PowerBook to test NVIZ.  Indeed, some problems.

 From Glynn's comment today, this is right - NVIZ is C linked to the  
Tcl/Tk libraries, so it will use whichever Tcl/Tk it was linked  
against at build time.  So it's not affected by GRASS_TCLSH or  
GRASS_WISH.

I also get an error starting gis.m:

child process exited abnormally

     while executing
"exec -- d.font romans >& /dev/null"
     ("eval" body line 1)
     invoked from within

     (procedure "run" line 6)
     invoked from within

     ("eval" body line 1)

     (procedure "MapCanvas::drawmap" line 43)
     invoked from within
"MapCanvas::drawmap $mon"
     (procedure "MapCanvas::display_server" line 9)
     invoked from within
"MapCanvas::display_server"
     ("after" script)

After clicking thru the error, no maps will display.

BUT, gis.m (same universal build of GRASS) DOES work on my MacBook.   
I suspect there is a cross-compiler build error here.  Now that I  
think about it, the font part of building GRASS is one place I had to  
fiddle with things - make wants to run a program to process the  
fonts... hm, maybe an endian thing.  I'll have to check that out.

I suspect if you get a PPC build to work, it'll be fine.  In fact,  
since NVIZ and wish have nothing to do with each other, you can do a  
normal X11 build, but use the Aqua wish when you run the GUI.

Ah, I see what you mean now.  And that's a nasty wiggling on the  
browser dialog box!  This DID work before.  Something that changed in  
the NVIZ source between my first success (the browser did work and I  
could add other rasters and vectors) and the refinements must have  
broke it (I only tested loading the initial raster after that).

More to investigate...


I also noticed the GUI layout problems.  I figured that was a  
separate issue, with the GUI widgets that are drawn natively by OSX  
(like buttons and menus) being a little bigger than in X11.
