Re: [osg-users] Rendering the scene multiple timeswith differentshaders.

I don't know how you perform your multi-pass rendering. But as far I understand the nodeMask, a node is traversed if the logical AND operator between the visitor mask and the node mask is not null. So, if you use two cameras, the first can have a mask to 0x1 to render the subgraph Node_1 and the

[osg-users] How to get world coordinate and normal of vertex in glsl

Hi, I build a indoor scene using osg2.4. Each object added to the scene is added to a MatrixTransform node which containing all the information of translation,rotation and so on, this MatrixTransform node is then added to the root. I have a problem that I use two cameras render the scene in two

Re: [osg-users] osg::ref_ptr difficulties

Vincent, I endorse what Peter said. The most important thing to remember with ref_ptr is that each ref_ptr gets its own pointer to the object. If you want to remove the original reference you must pass the ref_ptr by reference (using the & in the calling sequence) and modify it directly. -Er

Re: [osg-users] Small object frustum culling

Robert is saying you should create your scene graph such that it replicates a quad tree and separate the billboards in to geo-spatially partitioned groups See http://www.vis-sim.com/imgdp/dbpart1.jpg, your tree is like the last one 'Root B' which is a very bad tree for a scene graph The middle

Re: [osg-users] Small object frustum culling

Never used it, so I'm not sure if it would help or not, personally I prefer to build my scenegraph such that I control how its put together, but that's me ;) but the billboard node may ? Stop this work, maybe not ... He could certainly try and see if he gets back etc.. -Original Message---

Re: [osg-users] Small object frustum culling

Thanks for the example code. When I bring it up, I get cull ~5ms, and draw ~15ms. I then use the middle mouse button to drag all the billboards off the screen, and I get cull ~0.1ms, and draw ~0.3ms. So, obviously, frustum culling is working. However, performance is a cliff that only drops off whe

You have many good points. I've seen this topic come up many times in my nearly three decades of using countless online discussion forums. One thing I've learned: no matter how many resources and FAQs you make available, people, by their very nature, are social, and therefore value the interaction
