Hi Trajce, If you only need to display it, maybe clipplanes is what you are after. They also work fine with modern shader pipelines, where you can transform them inside the vertex shader to your liking. Cheers Sebastian Hi Community, is something like this available in OSG? Thanks as

[osg-users] Migrate shaders to glsl 4.1

I've been trying to migrate my shaders to OpenGL 4.1. What is the alternative to the fixed pipeline code, of the vertex shader: gl_TexCoord[0] = gl_TextureMatrix[0] * gl_MultiTexCoord0; gl_Position = ftransform(); I know I have ot create my own out vector, like "out vec4 texcoord", but

It really sounds like what you're doing is going to require geospatial integration, and for that, you'd be much further ahead using osgEarth, which has all sorts of geospatial features built in. Can you describe the bigger picture of what you're actually trying to _accomplish_ in the end, so we

Hi Uma, The tiff plugin uses libtiff 3rd party library that doesn't support geotiff. The OSG's gdal plugin does support geotiff but isn't loaded by default as the .tif extension will be mapped to the tiff plugin. To get the OSG to use the gdal plugin add a .gdal to the image filename, the gdal
