[osg-users] Transform Feedback

Hi, Has Transform feedback been integrated into OSG? Are there any examples around that anyone knows about? Thanks and Regards Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org

[osg-users] transform feedback implementation

Hello, today I want to share my experiment with transform feedback. I implemented an example from the book OpenGL Superbible, Fifth Edition. In Chapter 11 there is a spring mass system example. The aim is the calculation of the physics into the vertex shader. The result should have to transfer

Re: [osg-users] Transform Feedback

Hi Paul, Thanks for your reply. I have decided to try using draw callbacks, and the osg encapsulation of shader programs. However, I have another question. How can we access the OpenGL pointer to an osg::program containing shaders? We need this pointer to set up transform feedback. I

Re: [osg-users] Transform Feedback

Hi, I guess my first question was too vague. Sorry about that. I am still trying to use transform feedback on an entire scene inside osg. I have created a CustomDrawable class with a drawImplementation that can perform transform feedback on anything drawn inside it. I am now trying to draw

[osg-users] Transform Feedback

Hi, I am interested in using a geometry shader to do calculations on the GPU but instead of drawing the result, it should be piped back into a vertex buffer. A high level description of the process is: 1. Load scene and shaders to be used for transform feedback. (I do not know if I would

[osg-users] Transform Feedback

Hi, I'm using geometry shaders with openscenegraph. I'd like to ask if there are plans to implement transform feedback soon. I'm just wondering, since this extension seems to be NV only. Is this the same for geometry-shaders ( i.e. are there ATi cards that support geometry shaders) ? cheers
