Hi all, Excuse me to return on an old debate but I can't achieve VAO sharing with the current design...I really need an easy way for drawing with basevertices
To argue on the utility of VAO sharing among geometries, and (so on the replacement DrawElements to DrawElementBaseVertex as draw submission command): 1)GPU Pro 4 : Evaluating drawcall cpu overhead and GPU Draw Submission Limitations https://books.google.fr/books?id=_FnSBQAAQBAJ&pg=PA24&lpg=PA24&dq=cost+of+glbindvertexarray&source=bl&ots=1O1DTprEUD&sig=XBs_GMyYM8em72dF8fWnO3YeRKU&hl=fr&sa=X&ved=0ahUKEwiunsa8mMvOAhXDWRoKHXwuBN4Q6AEISzAE#v=onepage&q=cost%20of%20glbindvertexarray&f=true 2)Performances of my VAO proposal have conforted me in facts vaos should be shared and draw calls should be submitted with basevertex. 1VAO/Geom DrawCost 4 shared VAOs DrawCost 2 (My VAO proposal contains a little overhead that can be easily deported to a NodeVisitor) I would like other sentiments on the subject Cheers ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=70109#70109 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
