WebVC uses computed tomographic (CT) scan of a patient's abdomen and provides a virtual y-through visualization system through the virtual colon reconstructed from the CT scan [12]. In mathematics, conformal means "angle preserving". Conformal structure is a specail atlas of the surface, such that angles among tangentvectors can be coherently defined on different local coordinate systems. Furthermore, concepts in complex anylasis can be defined on the surface via conformal structure. … See more A surface with a conformal structure is called a Riemann surface. All metric surfaces are Riemann surfaces. The image illustrates the … See more Surface uniformization means that all metric surfaces can be conformally mapped to one of the three canonical domains, the sphere, the plane and the hyperbolic space. The figures show the uniformization for … See more
