The visualization of the potential distributions measured intraoperatively with 256 electrodes on the epicardial and endocardial surfaces of the human heart is important to guide antiarrhythmia surgery. A method has been developed for interactively visualizing the electrophysiological data gathered by these electrodes on a computer-generated 3D model of the heart. The epicardial and endocardial surfaces are extracted from computed tomography data and are modeled as triangle meshes. The datum at each vertex of a mesh is either directly available (if an electrode is at that vertex) or can be calculated by interpolation using a localized version of Hardy's multiquadric algorithm. Once the value at each vertex of a given surface is known, different interactive visualization techniques such as animation, direct manipulation, contouring and transparent surface rendering are used to enhance the underlying variations in potential distribution
