[osg-users] Rend to Texture Once
Hi, I want to render a ploygon to texture,I won't change this polygon unless the polygon data changes. what can I do to render the texture only once, instead of rendering every frame?

Re: [osg-users] About vpbmaster problem
Thank you very much for your reply! Yes,I want to do a smooth elevation transition from area with DEM to area without DEM. About this possibility: a) modify your DEM sources to a image format, and at the border of your DEM region blend the gray values smoothly into the null value Can you give me more information?The dem.tif is some of ASTER 30m Data.How I should do ?

Re: [osg-users] About vpbmaster problem
Thank you! How about strm 90m DEM? Do you make terrain in earth as I do? Cheers, GuiYe At 2011-05-17 17:35:48，Torben Dannhauer tor...@dannhauer.info wrote: Hi, You use ASTER data? Am I right that ASTER is public available? I played 2 years ago with the ASTER data as it was initially released. It has great resolution, but it had also lots of artefacts. Do you use raw or somehow corrected ASTER data? - As you can see, I'm on the never ending quest for public available DEM and texture data :) Well, in the DEM raster data, some value represents zero meters elevation. To achieve a smooth transition, you should blend at the border of your source images from your original value to that null value. In a geotiff, this would be a blending of the grey value (which represents the elevation). You can perform this blending in a graphical software like gimp. Your blending zone has to be a frame at the border of your DEM region. You have to blend from the original elevation value to the 0 meters elevation value -for example with a alpha value ramp (inside your blending zone 100% elevation and 0% 0-meters-color, at the outer border of your DEM-Data 0% elevation and 100% 0-meters-color) Sorry for that bad explanation.. :) Cheers, Torben -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39454#39454 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] About Image
Hello,Robert. Yes,you are right. But I don't know how to rewrite the program.Can you tell me how to do this??Can you give me a new example Thank you I guess at what you meant. Is it that you want to do an offscreen render of your scene at higher resolution that the frame buffer, and then write this to disk. If this is the question your are answering then the answer is to use a pbuffer or FBO to create the desired size of image, render to this, then copy the image and write it to disk. The osgscreencapture example has an example of using a pbuffer to do offscreen rendering.

Hi GuiYe,
At present the addSlave doesn't automatically tell the viewer to
realize windows, reset up threading and rendering support, which is
why you code isn't working.
What you need to do in you event handling is to call
viewer.stopThreading() first, create you new window/associated
view/camera then realize the new window and then call startTheading().

Hello,Robert.
Thanks for your reversion.I'm so happy that I can add a new window in
realtime.But there is a new problem :how to destroy the new window.I find that
stopThreading can't destroy the window.Thanks.
Waiting for you good news.

Hi GuiYe,
At present the addSlave doesn't automatically tell the viewer to
realize windows, reset up threading and rendering support, which is
why you code isn't working.
What you need to do in you event handling is to call
viewer.stopThreading() first, create you new window/associated
view/camera then realize the new window and then call startTheading().
Robert.
