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.

So internal format needs to be a float format (GL_RGBA16F_ARB, > GL_RGBA32F_ARB, GL_RGB16F_ARB, GL_RGB32F_ARB). > > Cheers, > Wojtek > > 2016-10-05 14:20 GMT+02:00 liu ming <[email protected]>: > >> yes，I am getting 0 and 1 in geometry shader,but my input values are : >> >> >> Code: >> *ptr1=osg::Vec3( 0.0,0.0,0.0); >> *ptr1++; >> *ptr1= osg::Vec3( 40.0,0.0,0.0); >> *ptr1++; >> *ptr1=osg::Vec3( 20.0,0.0,20.0); >> >> >> >> ------------------ >> Read this topic online here: >> http://forum.openscenegraph.org/viewtopic.php?p=68869#68869 >> >> >> >> >> >> _______________________________________________ >> osg-users mailing list >> [email protected] >> http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >> > >
