Re: [osg-users] INHERIT_RENDERBIN_DETAILS
Paul, There are several messages on the board that imply that INHERIT_RENDERBIN_DETAILS, when specified with a bin number, influences the CullVisitor to create a nested render order. I was under the impression that, if an application has a top-level rendering order over objects that it was possible to impose a rendering order over sub-elements of one of those objects. You see, we have polygons that occupy the same space, but we want the smaller ones to show up on top of the larger ones whenever possible. Is it not possible to do that, then? Seems like it would be something that OSG would want to allow. I'd prefer a solution that uses order, rather than some kind of polygon offset or funky state.

Re: [osg-users] INHERIT_RENDERBIN_DETAILS
Hi John -- Can you post an .osg file that demonstrates the problem in osgviewer? -Paul Robert, We are using getOrCreateStateSet()-setRenderBinDetails. What we have is this: osg::group1-osg::group2-osg::group3-osg::geode-osg::geomet ry, where group3 contains multiple geode-geometry children. group3 has setRenderBinDetails called without specifying INHERIT_RENDERBIN_DETAILS, Which means it is setting to USE_RENDERBIN_DETAILS by default, correct? geode has setRenderBinDetails called, specifying INHERIT_RENDERBIN_DETAILS. None of the other stuff has renderbin details set in the statesets, HOWEVER, there may be other statesets in the chain that do exist (I call getOrCreate). Maybe they all exist regardless of whether I call getOrCreate, but I am not sure of this. The geode/geometry subtrees also have a texture associated with them. They also have GL_DEPTH_TEST disabled, so that we should see the most recently drawn (highest renderbin #) when two geometries overlap or would normally conceal one another. This is not what's happenning however. Any ideas why this might be the case? I have been over the code and I'm quite sure that I've described the situation more accurately.

Hi -- Not sure what you mean by priority. The render bin number specifies relative drawing order of sibling Nodes and Drawables. If each of your Geodes' Drawables must get drawn in a certain order, then you should set the render bin number on the StateSet of each Geode's render bin; Drawables will be rendered in ascending render bin number order. -Paul _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Argentieri, John-P63223 Sent: Wednesday, December 12, 2007 12:08 PM To: OpenSceneGraph Users Subject: [osg-users] INHERIT_RENDERBIN_DETAILS Hello all.
