Re: [osg-users] How to overcome trnasparency blending distortion
Hi, Did you tried to set Blending Function ? osg::BlendFunc class, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA is always a good starting point.

Re: [osg-users] How to overcome trnasparency blending distortion
Hi, I just understood that the problem is about releasing the object and also other primitives that i've added into pyramidGeometry. Because reusing and updating the pyramidGeometry(i.e rotating about some axis in a simulation) each time the drawing methods were releasing and creating a new one(maybe per each frame) the object just seems distorted. So i've just controlled the pointers if they created or not and after that added the primiteves without releasing them. If anybody has the same problem i can write the wrong and true codes here ... Thank you!

[osg-users] How to overcome trnasparency blending distortion
Hi, when i'm drawing a transparent pyramid it is ok; but while i rotating via transformation matrix this pyramid outside this updating makes distortions in the pyramid just like the triangle primitives have patterns. I tried other blending modes else than GL_BLEND and mede stateattr protected etc. but didnt work. How i can overcome this? The little code that i wrote: Code: pyramidGeometry-getOrCreateStateSet()-setMode(GL_BLEND, osg::StateAttribute::ON); pyramidGeometry-getOrCreateStateSet()-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); Map3DFOVObject-addDrawable(pyramidGeometry.release()); FOVTransformMatrix-addChild(Map3DFOVObject.get()); [/code] -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44382#44382 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
