[osg-users] Multiple view auto rescale resulting image

Hi, I have a scene with 3 differents views. One global 600*600px, one following one node 600*600px and one following an other node 1200*600px the lase one rendering screen is rescale (2;1). How i can change it to have a larger view but without rescale objects? Thank you! Cheers, Anthony

[osg-users] Lighting an HeighField.

Hello, I am creating a scene composed of two objects : - A (yellow) submarine, and a osg::ShapeDrawable created from an osg::HeightField : The Seabed. I use a spot light to illuminate this scene. The spot light is positinoned 1 meter above the submarine, the submarine is 10 meters above the

Re: [osg-users] CompositeViewer issues

Hi Brad, Could you see if you can reproduce this problem with the one of the OSG examples, or a small tweak of one to reproduce this problem. If I can reproduce it reliably then there is a much better chance of spotting the culprit and finding a solution. Cheers, Robert. On Tue, Sep 21, 2010

Re: [osg-users] osg::Particle in shader get/set geometry [SEC=UNCLASSIFIED]

Hi Paul, In the OpenSceneGraph-2.9.9 dev release, and svn/trunk there is work by Wang Rui on osgParticle this provides support for using shaders with particles systems, there is also an example osgparticleshader that will illustrate how to use it. Robert. On Wed, Sep 22, 2010 at 5:49 AM, Paul

HI Anthony, There a several ways one could interpret your post. What do you mean by a larger view? What do you mean by rescale (2,1)? Robert. On Wed, Sep 22, 2010 at 8:25 AM, Anthony Face litllechic...@hotmail.com wrote: Hi, I have a scene with 3 differents views. One global 600*600px, one

Thanks for your answer... Now, osgspotlight example is working on my computer... (I didn't download the ressources file, shame on me). I will try to do exactly like in this sample, and I hope all wil be right ! So in this sample, they use a HeighMap and a osg::ShapeDrawable. You said that's

Re: [osg-users] [osgOcean] Light effect in osgOcean

Hello Adrien, So why using an OceanScene disable my lighting effects ?? osgOcean uses shaders for most of its effects, and these shaders assume directional lights. You will have to customize the shaders to do the right calculations for all types of light source. This is not a trivial

Check the source code. If I recall correctly, the loader reads in comment records and stores them as UserData in the scene graph, but I'm not sure about extension records. The only way to know for certain is to check the source. -Paul Brad Colbert wrote: Hello all, We would like to store
