Thank you for your answer Carsten, unfortunately (for us) we would use TextureBuffers. We will investigate this more deeper and if we will choose to use Multisampling with FBO I'm sure we will contribute any modification brought to OpenSG.
Regarding the performances I found this: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=233432&fpart=1 and this: http://www.mail-archive.com/opensg-users@lists.sourceforge.net/msg10723.html Thank you again, Josef On Wed, Jan 26, 2011 at 5:08 PM, Carsten Neumann <carsten_neum...@gmx.net> wrote: > Hello Josef, > > On 01/26/2011 01:52 AM, Josef Grunig wrote: >> I was curious about how to enable Multi Sampling in OpenSG2 with FBO? >> I tryied the RenderOptions class or enabling it manually by calling >> glEnable(GL_MULTISAMPLE); with no success. >> Context is correctly initialized... > > for an FBO to use multisampling the attached buffers would need to be > created with glRenderBufferStorageMultisample() and > glTexImage?DMultisample() respectively. > There is currently no support built into OSG::RenderBuffer and > OSG::TextureBuffer for these though, sorry.
