Re: [osg-users] CompositeViewer multiple windows, same scene problem

Hi Alvaro, I just did a quick test under Windows 7, with OSG 3.0.1 and Qt 4.8.2. Two views (created from GraphicsWindowQt) of a CompositeViewer in two windows can render the same node (lz.osg for my case) smoothly. Could you please provide more information about your implementation? If you are go

Re: [osg-users] Render passes and stereo handling

Hi Gaurav, A possible solution I think (but never tested it) is to set a draw callback to left/right render stage (stages can be obtained from camera->getRenderer()->getSceneView()->getRenderStageLeft(), and then use RenderBin::setDrawCallback... Oops). And you may know if left or right render sta

Hi Markus, Default LinesegmentIntersector is unable to handle intersections with lines and points. But PolytopeIntersector which will require a rectangle on screen (or a polytope in space) may do the work for you. The OpenSceneGraph 3.0 Cookbook (Packt Publishing) introduces how to use custom int

[osg-users] CompositeViewer multiple windows, same scene problem

Hi, We are having trouble using a CompositeViewer with 2 views in 2 windows, showing the same scene (same Node*). The first view (in addView order) is rendered correctly, but the second view is badly rendered with some missing or garbled geometries. If only one view is added, its rendering is

Re: [osg-users] Multithreading & Culling problems

We had a similar issue. We had a stereo rendering setup that used slave camera's to render the scene. The only thing the main camera did was to swap the buffers. Whats happened is when you do anything that will get bounding boxes of nodes invalidated, if you don't recalculate those they will be

Hi, Is there a way to know which eye (left/right) is currently being drawn inside osg::Camera::DrawCallback. There is the UserData field in RenderInfo, but I don't think I can use it for my purpose without having to patch osgUtil::SceneView.cpp - the patch being that I update UserData before dra

Hi John, Ther a number of different ways to get stats on scene graphs: The onscreen stats handling provides a range of options that may be sufficient - run osgviewer on your model and press 's' a couple of times to see the various different stats availble. One can also convert model to .osg or .

Hi Shuiying, I guess that there may be something wrong in the draw implementation of drawable B. Although OpenGL calls can be executable in custom drawables, it is still suggested that you apply all kinds of rendering states to the drawable using StateAttribute derivatives. But without looking at
