[osg-users] Switch node, and multiple views

Hi all, I have a scene graph containing a switch node (osg::Switch) having 4 children. What would be the best way to render this scene graph in 4 different views/viewports, with each child (attached under the osg::Switch) rendered in its own view? Thanks!

[osg-users] Double-click events in AdapterWidget / OSGQtWidget

Hi, I managed to modify AdapterWidget : public QGLWidget so that it recognizes double-click events as well, by adding the associated protected method virtual void mouseDoubleClickEvent( QMouseEvent* event ). However, whenever I double click within the OSGQtWidget (which inherits public

[osg-users] Animating large time-stamped series of data?

Hi all, what would be the best approach to animate huge time-stamped series of data in OSG? The data is in the format: (t0, x,y,z) (t1, x,y,z) (t2, x,y,z) ... I have hundreds of thousands of these tuples in a typical input file. The tuples themselves were generated using a

[osg-users] Multi-pass rendering

Hi, In my application, I have to perform the following operations: 1) render the scene into buffer A, using fixed GL pipeline 2) render the scene again into buffer B, using some shaders 3) render the scene again into the color framebuffer, using some shaders 4) superimpose (i.e. lay over)

Re: [osg-users] Multi-pass rendering

Robert, I'll start with the samples you mentioned. Thanks, Lars Hi Lars, The OSG support multi-pass, multi-stage rendering pretty thoroughly. There are plenty of examples that use various combinations of multi-pass. For starters have a look at the osgprerender, osgprerendercubemap,

[osg-users] Item buffer for lines in OSG

Hi, apologies for a relatively long post I have an old OpenGL application which uses a so-called item buffer for lines. This buffer is based on the idea to associate, upon loading, unique IDs to all the lines in the 3D model, then (on each frame) to: - render all these lines (each with a
