Re: [osg-users] osg::ProxyNode and osg::ComputeBoundsVisitor

Hello Oren, It seems that the node isn't loaded at all. As I do something similar in my database compiler, I think you will have to actually load the proxy node at least once to calculate the correct bounds for it: You code is correct, but as you defer loading of the real model, the

Re: [osg-users] [osgCompute] Adding osgCompute::Computation during runtime does not work...

Hi Jens, thanks for your reply. Currently we DO NOT set those flags before realize() because using the osgCompute functionality is only a sub-case of the application (only needed when the user whats to deform a geometry). So if the user wants to start deformation osgCompute is initialized.

[osg-users] [osgCompute] Problem with the osgGeometryDemo example

Hi, we got a problem with the osgGeometryDemo example. This problem occurs on one developer machine only. The first devmachine works without problems - as far as I can see with the same software setup, but different hardware. Problematic machine: NVidia GeForce 9400GT (G96b, 16 cuda cores,

Re: [osg-users] [osgCompute] Problem with the osgGeometryDemo example

Hi Johannes, did you install the OpenSceneGraph-Data stuff. For me it seems that the example application is not able to find the cow.osg file. If that is so then the module is not being built. You can proof this by typing osgViewer cow.osg in your command line. Best regards, Jens

Hey Sebastian! Thanks for the interesting reply. So, I guess that explains why the dimensions of my bounding box are tending to infinity! I have some questions though: 1) what do you mean by load the proxy node at least once? does that mean to add the proxy node as a child in the scene or just

[osg-users] Is there a reason a why different scene statistics are collected in Renderer::cull and Renderer::cull_draw paths

HI Rodrigo, I don't what settings your used, or the hardware/drivers you are using so can't pinpoint what the problem might be. If you run osgscreencapture with --pbuffer-only you get the warning: $ osgscreencapture cow.osg --pbuffer-only osgscreencapture: argument to `--pbuffer-only` is
