[osg-users] Using osgDB to load text files or other non-OSG files?

Hi, I would like to use the osgDB architecture to load script and xml files, possibly other stuff. I would like to be able to use the CURL plugin to load these files from the net, which means I can't simply get a path with osgDB::findFile and fopen that. Ideally I would like to enter a path or

Re: [osg-users] Scaling while retaining the center position of the object

Hi Jonathan, I have done something similar to what you need by writing a custom dragger callback instead of the standard one assigned to the manipulated objects. In my case I manually rebuild the the motion matrix to apply to the target matrix transform, instead of getting the one that the

Hi Ricky, Thanks for the reply. I had noticed the ScaleUniform Command and couldn't see any way to send it. I'll maybe give that a try. Cheers, Jonathan -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51436#51436

Re: [osg-users] [forum] Throttling OSG

Hi, you could change the frame scheme from CONTINUOUS to ON_DEMAND. Or look into viewers run() function and perform the different traversal calls per frame manually. Cheers, Torben -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51438#51438

You can look at the maya2osg project at http://sourceforge.net/projects/maya2osg/. The problem is that it hasn't been maintained recently. We are having the same issue and in the past we exported or models to obj format, then converted to pfb with a custom performer library to handle some special

[osg-users] Sharing culling results among multiple cameras

Let's say I have two cameras with identical view frusta, say a main camera and a camera for reflections that contain the same objects, only flipped. Is there any way I can avoid incurring the overhead of culling once for each camera, when the results will be the same for both? Basically I'd like

Hi, I'm intersted by this topic, because in my application, sometimes I need to render the same scene multiple times. For example, I render the scene a first time to generate a regular OpenGL image. Then I render with different shaders/textures to generate an image with computation results

Re: [osg-users] Sharing culling results among multiple cameras

One approach is to create a custom RenderBin. The cull pass collects RenderLeaf objects and puts them into the bin. Each RenderLeaf contains a single Drawable along with its modelview matrix, projection martix, and state graph. You can tweak these properties at draw time, or even draw a leaf
