Hi, In visual studio you can 1) Set your plugin project as startup project 2) Specify the osgviewerd.exe as Command (in the Debugging section) 3) Specify the model that triggers your plugin as command line argument (in the Debugging section) 4) Set a breakpoint in your plugin Running should now

[osg-users] nVidia card textures memory

Hello, First I know my question has nothing to do with OSG, but a lot of OSG users might come across this subject and any guidance would be most appreciated. The questions I ask regard the nVidia textures memory and how to access it. 1. I'd like to pass data from nVidia texture memory to

Re: [osg-users] How to debug my own plugin library?

Hi, you could hardcode a breakpoint into your plugin during its initialization, see http://msdn2.microsoft.com/en-us/library/k4wx2tde(VS.80).aspx then set additional breakpoints as needed cheers -- mew On Mon, Apr 7, 2008 at 12:05 AM, Bo Jiang [EMAIL PROTECTED] wrote: Dear all,

[osg-users] Callback multiple

Hi all, I have made some NodeCallback. for the moment, 2 NodeCallback are running at the same time... they use the osg::Timer.. But when I've added the second one, the first seems to do nothing... Is there any recommendation to add some Callbacks on the same scenegraph ? Thanks. Regard.

Re: [osg-users] OpenGL codes issues in osg version 2.2

Hin, That looks like something that might be caused by a macro from another header messing up osg/BlendFunc. You might want to look in osg/BlendFunc and see if there are any strings near where the error is that might be macros defined in another header. Specifically I know there is some MS

Re: [osg-users] Uniforms and state sorting

Ok, I'll see if I can find anything in CullVisitor between 1.2 and the latest. I can't just attach a single uniform on top of everything because I *only* want to change the value for the light points, not for the whole model. For the record, I ran out of time for our project at work and ended up

[osg-users] Is it possible to extend OSG to support CGFX ?

Re: [osg-users] Callback multiple

Hi Vincent, Callbacks are responsible for traversing the subgraph so you need to call traverse on the node, or use the NodeCallback::traverse method. See other examples of NodeCallbacks in the OSG to see this in action. Robert. On Mon, Apr 7, 2008 at 3:18 PM, Vincent Bourdier [EMAIL PROTECTED]

Re: [osg-users] nVidia card textures memory

I've checked compiz. They use extension GLX_EXT_texture_from_pixmap that is implemented specially for X11 systems if I understood correctly. I'm developing on windows and could find in my brief search any analog windows extension. But besides that it looks pretty cool with some ideas I thought

Re: [osg-users] Is it possible to extend OSG to support CGFX ?

Hi Jerome, You'll need to extend the OSG to do this, but the OSG is designed to be extensible so this needn't be a show stopper. Avenues of investigation would be to look at osgNV project and the effects support in Collada. AMD/ATI recently release a viewer that renders effects RenderMonkey via

Re: [osg-users] nVidia card textures memory

Hi Guy, I don't know of any extensions for mapping/copying memory from one card to another directly. NVidia will have such code in their drivers, but its something that is hidden from the OpenGL. However, there are still OpenGL features that can help out a little. First up Frame Buffer Objects

Hi Nicolas, I haven't personally tried you particular usage combination so can't advice from personal experience. It might be that we need to add some extra code into osgViewer::ViewerBase/CompositeViewer to add this type of usage combination with it picking up better on current threading,
