(solved) Re: [osg-users] osgdem: How do I use the --xt / --yt cmd line args?

[Mike Logan]

As I suspected, this was my usage error... The --xt --yt --zt  are using the "scaled" units after   --xx --yy ---zz  are applied. I see now in the code, the geotransform just a normal  osg::matrix  populated by all the    --xy --yx  etc...   arguments. sorry for the noise.. ml On Sep 8, 2006, at 11:42 PM, Robert Osfield wrote: Hi Mike, Looking at osgdem, the --xt and --yt do set the transaltion part of the geo transform matrix for that dataset, so outwardly it would be seem to be setting something.  Perhaps the interrnals of osgTerrain arn't taking this translation part of the geotransform in to account, but they should, the code normally just uses the matrices complete. I'm rather squeezed for time right now, but if I get a chance later I'll try and reproduce you usage case to see if I can reproduce the problem. Robert.

There is NO GEOreferenced data here, all  PNG terrains. The use of --xx and --yy work fine, but my hi-res piece is   always in the corner sharing   x=0,y=0 with the lower res  piece. I thought this might move the hi-res portion somewhere away from the origin: osgdem \ --xx 1000 --yy 1000  -d   2k_by_2k_terrain.png \ --xx  100 --yy  100 -v 0.1  --xt 5000 --yt 5000  -d hires.png \ -l 5 -o test.ive -a test.osga In fact, after many tries, I can't see that --xt and --yt do anything? help, ml Michael Logan  QSS Group,Inc / NASA Ames Research Center Task Lead / Visual Cueing & Simulation Visualization Engineer / Adaptive Control Technologies _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ Michael Logan  QSS Group,Inc / NASA Ames Research Center Task Lead / Visual Cueing & Simulation Visualization Engineer / Adaptive Control Technologies MS 262-6, Moffett Field, CA, 94035  (650)-604-4494
