xinshi

A VRML 2.0 model of a human left ventricle Xinshi is a package for automatic fitting of labeled piecewise smooth subdivision surfaces to sparse, noisy 3d point data. If your browser supports VRML 2.0, you can view the 3d model of a live human left ventricle shown at right, which was reconstructed from a set of 2d images produced by a 3d ultrasound device. (If you have an older VRML plugin that has trouble with VRML 2.0, try this VRML 1.0 model .)
