Figure 1: We present a new technique to extract high quality triangle meshes from volume representations of geometric objects.The two main contributions are an enhanced distance field representation and an extended Marching Cubes algorithm.The above figures show reconstructions of the well-known "fandisk" dataset from its distance field representation.The distance field has been sampled on a uniform 65×65×65 grid.The far left image shows the standard Marching Cubes reconstruction, center left is the reconstruction by the same algorithm but applied to the enhanced distance field with the same resolution.Center right shows the result of our new extended Marching Cubes algorithm applied to the original volume data, and finally on the far right we show the reconstruction by our new algorithm applied to the enhanced distance field.The approximation error to the original polygonal model is below 0.25 %.
