[osg-users] OSGQT lib not created
Hi, I'm using OSG 3.2.1 version, QT 5.3.1 msvc 2013, cmake 3.0 to build on VS 2013. except osgQT lib all are created and working fine. Why OSGQT lib not created ? ... Thank you!

[osg-users] OSG Server DOWN for mainteinance
Hi osg-ers The OSG server containing the old trac and the svn will be down for some hours for mainteinance.

[osg-users] (no subject)
Hi, Is it possible to display stereo 3D rendering for green-magenta anaglyph glasses in OpenSceneGraph? (as opposed to red-cyan glasses) I can get stereo working well with old-fashioned red-(blue-cyan) glasses. Is there a way to change the color settings of anaglyph mode? Below is a complete twelve line python program that renders in stereo for red/cyan glasses. [code] from osgswig import osg, osgDB, osgViewer, osgGA print %d.%d.%d % (osg.OSG_VERSION_MAJOR, osg.OSG_VERSION_MINOR, osg.OSG_VERSION_PATCH) # prints 3.2.1 cow = osgDB.readNodeFile(cow.osg) # Use custom DisplaySettings to create a stereoscopic view display_settings = osg.DisplaySettings() display_settings.setStereoMode(osg.DisplaySettings.ANAGLYPHIC) # Red-cyan ONLY !?!? display_settings.setStereo(True) viewer = osgViewer.Viewer() viewer.setSceneData(cow) viewer.setUpViewInWindow(100, 100, 500, 500, 1) viewer.setDisplaySettings(display_settings) viewer.run() [/code] How would I modify this program to display stereo for modern green-magenta filtered glasses?

Re: [osg-users] is osgEphemeris incompatible with osgShadow?
Hi, I am working to integrate osgShadow and osgEphemeris into Delta3D for the 2.8.0 release and have encountered this same issue. I managed to track it down to the setting of the TexGen stateset on texture unit 1. osgEphemeris sets OBJECT_LINEAR where as osgShadow sets EYE_LINEAR. osgEphemeris renders first and that renders correctly but when the shadow coordinates are computed the OpenGL state still appears to be set to OBJECT_LINEAR. A simple work-around is to just change one of the texture units, but it seems as though it should just work. Any thoughts would be greatly appreciated!

Re: [osg-users] (no subject)
HI Christopher,
Currently the ANAGLYPHIC stereo support is hardwired to red-cyan.
Curiously you are the first to ask for anything else.
To implement for other interpretations of anaglyphic you'd need to
implement it using osgViewer::View slave Camera's, one slave Camera for the
left eye and one for the right - you'd attach the appropriate
osg::ColorMask for each slave Camera to get the effect you want.
The code that sets up stereo in svn/trunk can be found in
OpenSceneGraph/src/osgViewer/View.cpp assignStereoOrKeystoneToCamera(..)
method, the code block of interest looks like:
switch(ds-getStereoMode())
{
case(osg::DisplaySettings::QUAD_BUFFER):
{
// disconect the camera from the graphics context.
camera-setGraphicsContext(0);
// left Camera left buffer
osg::ref_ptrosg::Camera left_camera = assignStereoCamera(ds,
gc.get(), 0, 0, traits-width, traits-height, traits-doubleBuffer ?
GL_BACK_LEFT : GL_FRONT_LEFT, -1.0);
left_camera-setClearMask(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
left_camera-setRenderOrder(osg::Camera::NESTED_RENDER, 0);
// right Camera right buffer
osg::ref_ptrosg::Camera right_camera = assignStereoCamera(ds,
gc.get(), 0, 0, traits-width, traits-height, traits-doubleBuffer ?
GL_BACK_RIGHT : GL_FRONT_RIGHT, 1.0);
right_camera-setClearMask(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
right_camera-setRenderOrder(osg::Camera::NESTED_RENDER, 1);
You could implement this without going via the osg::DisplaySettings/default
configuration, the other alternative would be to extend DisplaySettings and
the View.cpp code to handle customization of the anaglyphic settings.
Robert.

[osg-users] display quad textured with osg::TextureCubeMap
Hi, I understand the necessary steps to render to texture then display said texture on a quad for display. Now, I am rendering a scene to an osg::TextureCubeMap and want to display it, or one face of it, on a quad for display. I can't seem to get this to work. I tried the following to create 2D texture to display the slice, but it doesn't seem to work. Code: // create cube map texture osg::TextureCubeMap* rttTextureCubeMap = new osg::TextureCubeMap; // etc. etc. // setup up rtt camera ... snipped osg::ref_ptrosg::Texture2D textureToDisplay = new osg::Texture2D; textureToDisplay-setTextureSize( rttTextureCubeMap-getTextureWidth(), rttTextureCubeMap-getTextureHeight() ); textureToDisplay-setInternalFormat( rttTextureCubeMap-getInternalFormat() ); textureToDisplay-setSourceType( rttTextureCubeMap-getSourceType() ); textureToDisplay-setSourceFormat( rttTextureCubeMap-getSourceFormat() ); textureToDisplay-setImage(rttTextureCubeMap-getImage(0) ); // create textured quad with textureToDisplaysnipped CD ...
