Hi Robert I apologize if the term "frustrated" i used in the title of my post could be interpreted provocative by one as invested in osg as you are. I was a little upset by our recurrent misscommunications at the moment i wrote. In fact, I was sure to be the only one with this problem...
Moreover, all the "issues" i talk with you are linked (TFFB,IndirectDraw,BaseVertexDraw..). So it's a real pain in the brain for me to find a common brainstorm start. For ex: In a previous post http://forum.openscenegraph.org/viewtopic.php?t=16470&highlight=basevertex I talk about an example code overriding osg default bo allocation policy in order to optimize drawsubmission with BaseVertex drawcall and shared VAS.Without a way to serialize this policy override I'm not able to serialize my work and would have to use a dirty post loading visitor so the start of our discussion could be this use case...(as it really gives double performance in all bench I've done ) The example https://github.com/mp3butcher/OpenSceneGraph/tree/master/examples/osgSharedVAO The minimum mod i added to remove useless calls to glBindVAO > https://github.com/mp3butcher/OpenSceneGraph/blob/8275ab2dd2e325f19c0312ec340392fc677bdd33/include/osg/VertexArrayState > https://github.com/mp3butcher/OpenSceneGraph/blob/8275ab2dd2e325f19c0312ec340392fc677bdd33/include/osg/State > https://github.com/mp3butcher/OpenSceneGraph/blob/8275ab2dd2e325f19c0312ec340392fc677bdd33/src/osg/State.cpp > https://github.com/mp3butcher/OpenSceneGraph/blob/8275ab2dd2e325f19c0312ec340392fc677bdd33/src/osg/VertexArrayState.cpp ....(when you'll have time to spend of course..:/) Again, sorry to be a pain in the $#%% adding new problems in the bag. robertosfield wrote: > Hi Julien, > > On 29 March 2017 at 15:49, Julien Valentin <> wrote: > > > Okay, i'll ask you a simple question: > > How BufferIndexBinding can be serialized? > > if we follow the rule homogeneity BufferIndexBinding atttribute should be a > > BufferData and not BufferObject+index+offset+size (to hide bo details is it > > is) > > What is your feeling of such change in BufferIndexBinding? > > > > I'm not the author of BufferIndexBinding and haven't personally needed > to use it yet, which is one of the reasons why I'm suggesting a > concrete example of usage so how all the classes interrelate and what > needs to be done. > > It may be that BufferIndexBinding needs to evolve or that > BufferData/BufferObject also need to be adapted with it.
