[GRASSLIST:533] Re: nviz with transparency is horrible slow

[Wolfgang]

Hello Glynn,

thanks again for your information! I played this evening with povray, 
this is also not a realtime 3d encoder, but offers more possibilities 
and with r.out.pvr building topologies is not that hard. I also habe a 
3d- viewer for windoofs so that I can see with real time rendering what 
I want. But as usual all software has it's disadvantagages and it (the 
3d viewer on win) offers  no "movie" export.
