[GRASS-user] NVIZ and 3D polygon

[William Kyngesburye]

Did you build from source or are you using one of the binaries?

I have verified that my binaries run on Leopard, except that I didn't  
check NVIZ.  There may be compatibility issues with OpenGL on the new  
X11 - Apple did some cool and weird stuff with Leopard's X11.

When I built on Leopard, I got NVIZ to run, though there were some  
initial redraw glitches so there may yet be OpenGL issues on Leopard.


It may be as simple as the X11 display setting.  One of the cool new  
X11 things is that you don't need to start X11 yourself - it starts  
when needed.  In fact, you shouldn't start X11 yourself, and you  
should not have it in your Dock, or you will get multiple copies in  
your Dock.

For displays to work, you must NOT set the $DISPLAY variable in your  
shell.  Make sure you remove it from any shell startup scripts  
(ie .bash_profile and .bashrc).  It may also be in ~/.MacOSX/ 
environment.plist from other software installs.

When I get things running smoothly on Leopard, I'll find a place to  
add this info in the GRASS wiki, as well as the OSX readme for the  
binary install.
