Publisher review:Modal Warping - Modal-Warping graphical demo This work was concerned in RT simulation of elastic objects. Specifically, it is a prototype test of the work of Ko & Choi titled 'Modal Warping' , which synthesises former works under the name of 'stiffness warping' and the classical approach known in CG circles as 'modal analysis'
This prototype mainly illustrates some graphics and optimization techniques.
The main function is ModalWarpingCheckModes, which takes as argument a valid VOL-file name. VOL is the output format of the freeware NETGEN - which is a rough and simple textual encoding of tetrahedral mesh info. Several VOL models are included (from small to large): 'y', 'sphere', 'stomach' and 'tissue_cut2'.The routine performs a certain generalized eigen-decomposition (which can take several minutes for the larger models, depending on your system), and saves the results to a mat-file in the current folder. Future calls to the function would look for the appropriate mat-file, and compute the eigendecomposition only if it isn't found - so from 2nd launch on the init would be much, much faster.The generated mat files range in size from 80K (for 'y') to 40M (for 'tissue_cut2') - that's why i didn't include them in the archive - so allow for sufficient disk space.example:ModalWarpingCheckModes('y')ModalWarpingCheckModes('sphere')ModalWarpingCheckModes('stomach')ModalWarpingCheckModes('tissue_cut2') Requirements: ยท MATLAB Release: R2006a
