Hi, I'm new to osg. My version of osg is 2.8.0 and vpb 0.9.10 (WinXP). I have generated a terrain scenegraph with a command like osgdem -t bottomtype.tif -d elevation.tif -l 3 -o terrain.ive --POLYGONAL and I have added it to my main scenegraph and it works fine. Now I want to render the terrain scenegraph with a shader to modify some things, but without uniform statements I have no access to the texture data. Are there any parameter for osgdem will generate these uniform statements for my application? Perhaps I look over the right parameter an do not see the right way. (For a quick and dirty workaround I converted the terrain.ive file into terrain.osg and added the uniform statement at the state set with an editor and it works!) I'm also interessed on knowing which subtile is rendered by the shader!
While converting the terrain.ive into terrain.osg with osgconv terrain.ive terrain.osg -O OutputTextureFiles I observed a loss of precision in some floating point parameter. I found the option parameter (-O precision) but it seems not to work. What is the correct syntax for that option parameter and which parameter values will work? Thank you!
