| Abstract: | This paper proposes a method to display 3D visualization of cardiac electrophysiologic parameters. In this method, a 3D surface is transformed with Delaunay triangulation to a plane. The values are interpolated in the barycentric coordinate system. Then a smooth epicardial model is reconstructed with a distribution of electrophysiological parameters on its surface. This method provides an intuitive and fast way to display epicardial electrophysiologic parameters. |
