[osg-users] Create a custom RenderStage

Hi, I use differents custom RenderStages : as pre-renderstage for pre-processing and as post-renderstage for post processing. These processing are executed using FBO render targets. Currently I'm doing that with slaves cameras, but : - the RenderStage class is derived from the RenderBin class

Re: [osg-users] Create a custom RenderStage

Hi Aurelien, The OpenSceneGraph Cookbook provides a simple Depth-of-Field example that implements post-processing work with multiple camera ndoes (not slaves). You may have a look at it at https://github.com/xarray/osgRecipes . FYI, It also includes an osgeffectcompositor example that provides an

Re: [osg-users] Create a custom RenderStage

Hi Wang, Thanks for your quick answer ! I'm already doing pre and post-processing of various king : tone-mapping, DOF, motion blur... using multiple cameras, slave or childs. Now I'm trying to create custom renderstages, without multiple cameras, but using a RenderBin prototype. This could be

Re: [osg-users] Create a custom RenderStage

Hi Aurelien, Oh, that's an interesting idea that not intrude the scene graph but with a special renderbin mode. I have never tried but know there is a Camera::setRenderingCache() method that would provide RenderStage instance corresponding with each camera node. It is used in osgUtil/CullVisitor,

Re: [osg-users] Create a custom RenderStage

Thanks for these informations, I'll try to do something with that. I was thinking about a more simple approach : - register a RenderBin prototype which is a class deriver from RenderStage - use this renderbin for some nodes I've already created custom RenderBin prototypes (it's pretty easy,

Re: [osg-users] Create a custom RenderStage

The CullVisitor traverses the scene graph and assembles a render graph. The structure of the render graph is composed of RenderBins, some of which might actually be RenderStages. The current RenderBin changes under two circumstances: - The CullVisitor encounters a Node with a StateSet whose

Re: [osg-users] Create a custom RenderStage

Hi Paul, Thanks a lot, these are very intersting informations ! Actually, I need to use custom RenderStages and not only RenderBins because I want to render to different FBO's (for pre and post process purposes) - Editing manually the RenderGraph sounds a little bit complicated to me -

[osg-users] Coursera Classes Coming Up!

Hey guys! You've probably heard by now, but there is a really great up-and-coming website/organization/movement called Coursera that I learned about last year. http://www.coursera.org https://www.coursera.org/user/i/cec974e9434316ce7625ee9df772effe There are some REALLY great math and

[osg-users] Animating articulated osg models

(NOTE: I posted this question directly to the forum some time ago, but my messages sit under moderation for too long to be useful. I decided to attempt to post via the mailing list) We are developing an osg-based application which requires the use of various vehicle models, which we have

Re: [osg-users] Animating articulated osg models

Hi, In general, am I correct in expecting setUpdateCallback to behave this way? = yes In the situation you describe, the osg model is shared against multiple parent, event if there is a specific matrix transform : Common parent | |- Matrix_1 - Osg_Model | |- Matrix_2 - Osg_Model | |-
