hi Wojtek,Thank you very much,you perfect solved my problem.According to your code,Texture2D worked,maybe it is something wrong about Texture1D. Thank you. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68887#68887

Hi Sebastian, maybe related maybe not, I have seen this in uniform setting. Internally the code of the uniform setting is using ::vector::first() even for empty vectors .. just a hint and again, maybe not that issue Nick On Wed, Oct 5, 2016 at 5:41 PM, Sebastian Messerschmidt <

Re: [osg-users] blending with shader

Taking a quick look at the code, yes it seems like it is a good example. So basically taking a quick read of this, you render your scene to a texture, then render a dome basically setup to do your warping, with the results from the render to texture, as its texture. You basically want to

Hi guys, Here is the repro code. In cmake project. Change use_data1D value in test.cpp to see the problem. One note: I tested it with GL 3 Osg build. There may be issues I omitted if you run it with GL1/GL2/GL3 compatibility OSG build. Cheers, Wojtek 2016-10-05 14:38 GMT+02:00 Wojciech
