                         surfaces. The method combines recursive simplicial subdivision of 
                         the domain and point sampling along curves on the surface. We 
                         avoid cracks in the polygonal mesh by determining the optimal 
                         sampling rate along the edges of a cell before subdividing it. The 
                         method is suitable for surfaces with low variations, such as 
                         bicubic patches, as well as for surfaces with high variations, 
                         such as height fields.",
