Hi
This see-through/bleed-through artifact is due to the granularity of sorting used by all scene graphs including OSG, this happens because things are sorted a geometry node level and not at a per primitive level , using this method it is reasonable fast and in most cases give good results, but with certain poorer database designs or built scene-graphs where geometries overlap etc then you will see these types of artifacts Basically the way you minimize these types of artifacts is to re-structure your scene graph and or models such that they minimize overlapping bounding sphere and boxes. Please do a search of the mailing list and a google, this type of bleed through has been discussed at length on this list several time, many times on the old performer , Vega and Multigen list and forums ( I know I have mad emany lengthy posting to these lists on this subject over the years http://www.mail-archive.com/osg-us...@openscenegraph.net/ http://www.multigen-paradigm.com/cgi-bin/Ultimate2.cgi http://www.presagis.com/peer_forum/ http://oss.sgi.com/projects/performer/mail/info-performer/ ____________________________________________________________________________ __ Gordon Tomlinson <mailto:gor...@gordontomlinson.com> gor...@gordontomlinson.com IM: <mailto:gordon3db...@3dscenegraph.com> gordon3db...@3dscenegraph.com <http://www.vis-sim.com/> www.vis-sim.com <http://www.gordontomlinson.com/> www.gordontomlinson.com ____________________________________________________________________________ __ From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of rguru k Sent: Tuesday, July 14, 2009 6:35 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Help me to solve this problem hai all, i am using openscenegraph for rendering .flt files and im new to it.Using osgviewer i can walk thru .flt file. my model(.flt) is forest terrain. my problem is, i am seeing white line between two trees.what may be the problem? is it problem of visual database? i have attached image showing the problem.i have marked the problem in red. Please help me to find out the solution. wht is the problem & solution? Thanks in advance.
