TABLE II. Fitting Results for the VM Mesh.
Summary of the VM fitting results obtained by fitting piece-wise bi- and tri-cubic Hermite surfaces to digitized cyrosection photographs from the VM. The RMS errors (mm) are between the digitized data points and their orthogonal projections onto the fitted surfaces.
