Re: [osg-users] Multipassshading in OSG v1.2

Hello all, thanks for the answers! I have tried a look to the osgFX and to the source code (thanks Christian). One question I have. See I that right that I can just use Multipass sading at the time in OSG. I have to write my own solution like what you have posted Christian, or do the

Hi Guillaume This look like a use of library with different version Have you rebuild and reinstall OSG before run your test. David 2007/10/11, Poirier, Guillaume [EMAIL PROTECTED]: Hello ! I just downloaded version 2.2 and switched. The only modification I've made to my code that was

Re: [osg-users] Multipassshading in OSG v1.2

Bonjour Guillaume, I am attaching some code I've made that works for me to do what I call ModelEffects (multi-pass shaders on models) and PostEffects (multi-pass post-rendering on screen) that work with both Cg and glsl. I'm interested in seeing what you developed, but your attachment came

Re: [osg-users] rendering edges of an object

Hi! I'd like to know whether hidden line removed (silhouette edges) rendering can be achieved with OccluderGeometry class ? In addition, i have found Shi Yazheng's article (http://www.cs.umu.se/education/examina/Rapporter/ShiYazheng.pdf) implementing SEDGeode, which seems a good solution

Re: [osg-users] osg gui solved!

Correct, for performance reasons OSG does not save/restore the GL state across GL calls. There is simply too much state to do that efficiently (without the deeper knowledge encapsulated in the non-OSG GL code) Instead, OSG keeps track of the state as OSG changes it. If you change that state

Re: [osg-users] Multipassshading in OSG v1.2

I've seen a lot of posts lately regarding multi-pass shading. I think the core osg should probably offer more high level capabilities wrt shaders. I am attaching some code I've made that works for me to do what I call ModelEffects (multi-pass shaders on models) and PostEffects (multi-pass

[osg-users] Texture Memory supposed leak

Hello, I read a message concerning texture memory cleanup. Robert asked the user if he was opening and closing contexts. I am also having texture memory issues, and I AM opening and closing contexts. How are these two things related? Thanks for your help. Sincerely, John

[osg-users] camera attached to a node

good afternoon- I was looking at the NPS tutorials and it was mentioned in tutorial 11.1that a osgGA::TrackerManipulator can be used to attach a camera to a node. I tried this, (by attaching the TrackerManipulator to the node in question, then manually setting my view matrix using the

[osg-users] SceneView and texture unloading

I manage my own OpenGL texture sharing. Each of my multiple OS-Windows has a SceneView and the scene graph is shared. When I set my smart pointers to zero, it seems as if the textures are not properly unloading. This is a big problem for us. How can I correct it? If I extend

Re: [osg-users] camera attached to a node

Santosh- Yes, I did. But I'm sure I made a mistake somewhere :) After instantiating the node tracker manipulator, I bind it to a node, set the minimum distance, tracker mode and rotation mode like so: nodeTracker-setTrackNode( rootNode-getChild(1)-asGroup()-getChild(0) );
