Hi,
The specs on the HMD that I am working with calls for the view on each eye be
rotated outward by 13 degrees. However when I do this I can see what appears to
be a clipping plane. If both cameras are looking straight ahead, there is not a
problem. However I do need to rotate them outward.
int xoffset = 40;
int yoffset = 40;
// left window + left slave camera
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits;
traits->x = xoffset + 0;
traits->y = yoffset + 0;
traits->width = 600;
traits->height = 480;
traits->windowDecoration = true;
traits->doubleBuffer = true;
traits->sharedContext = 0;
osg::ref_ptr<osg::GraphicsContext> gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0,0, traits->width,
traits->height));
GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT;
camera->setDrawBuffer(buffer);
camera->setReadBuffer(buffer);
this->addSlave(camera.get(), osg::Matrixd::rotate(-13,
Vec3f(0,1,0)), osg::Matrixd());
}
// right window + right slave camera
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits;
traits->x = xoffset + 600;
traits->y = yoffset + 0;
traits->width = 600;
traits->height = 480;
traits->windowDecoration = true;
traits->doubleBuffer = true;
traits->sharedContext = 0;
osg::ref_ptr<osg::GraphicsContext> gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0,0, traits->width,
traits->height));
GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT;
camera->setDrawBuffer(buffer);
camera->setReadBuffer(buffer);
this->addSlave(camera.get(), osg::Matrixd::rotate(13,
Vec3f(0,1,0)), osg::Matrixd());
}
Thank you!
Cheers,
Robert
