Robert Osfield 1d9e7f144b From Michael McDonnel, "The tessellation shader example has a small bug.The middle of the ... geometry is clipped as soon as it is tessellated. The clipping is probably caused by rounding errors because it is only in one spot. The clipping disappears when the camera is moved, and reappears when it is moved back. Expanding the the bounding box fixed the clipping bug." Tweaked by Robert Osfield to expand it to a -1 to 1 unit box. Actual clipping bug is not due to rounding errors but the shaders creating vertices outside the bounding box of the original input vertices git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@14747 16af8721-9629-0410-8352-f15c8da7e697		2015-03-02 12:09:25 +00:00
