Re: [osg-users] std::vectorbool performance issue

You can try to use OSG_BUILD_KDTREES=on env var or turn it on in your program, also u can try using osg optimizer with SPATIALIZE_GROUPS option if u dont actually need (or can work some way around) initial graph structure. Cheers, Sergey -- Read this topic online here:

Re: [osg-users] FBO setup failed

Difference is that in first variant you attached only image to camera, and it getting updated by copying framebuffer object data into image, then texture gets updated from that image, and framebuffer object most likely will be 8-bit per channel. In second variant u have both texture and image

Re: [osg-users] Manipulate the stereo view (render to texture).

Sheck osgPPU, its nodekit for doing render to screen aligned quads (for posteffects and such), there u can build chains of RTT targets with nodes feeding data to each other. Cheers, Sergey -- Read this topic online here:

Re: [osg-users] Rendering left right stereo frames in separate threads?

Hi Brian, The current stereo support in the OSG is provided by the osgUtil::SceneView class, this is an old class that have survived through todo because it's still be useful for managing low level rendering, it is set for eventually replacement though. SceneView being old and quite primitive

Hi Licheng, You don't mention which version of the OSG you are using, or whether you've got the source and have compiled it. If you think the function is undefined then go source the source files and double check. You have access to svn/trunk and the dev series so you can easily cross

[osg-users] Vertex visualized problem, processed via shader.

Hi, I have a model with a skeleton that moves by using skinning shader. The problem is that with some moves and according to the position of the camera, some parts of the model vanish. I guess it will be something related to boundingbox ... What would be the best method to update this? Thank

Re: [osg-users] Manipulate the stereo view (render to texture).

HI Christoph, I would recommend setting the stereo yourself in osgViewer using two slave Camera, each of which renders to a separate FBO based texture, and then have a third slave Camera that rendered a screen aligned geometry with the textures plus any shaders/state that you want. The

[osg-users] Texture coordinate calculation in vertex shader

Hi everybody! I'm using osgShadow::ShadowMap on my scene. Also I have written my own vertex and fragment shaders. When coming to apply the shadow effect in the fragment shader I have to access the shadow map. The original shader uses just shadow2DProj( osgShadow_shadowTexture,

Re: [osg-users] Vertex visualized problem, processed via shader.

Hi Aitor, Still not much help. How have you implemented the animation? Using osgAnimation? Your own custom scene using osg::Geometry and own shaders... We don't have the paranormal ability to guess all this stuff. Robert. On Mon, Sep 13, 2010 at 10:50 AM, Aitor Ardanza aitoralt...@terra.es

Hi Werner, I doubt these five lines kill your framerate. Fixed pipeline on modern graphics boards these days is implemented internally on shaders and must do the same. There must be something else in your vertex shader approach that goes wrong... Wojtek
