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_ptr<osg::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_ptr<osg::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.
