Adaptive Re nement for Mass Spring Simulations

Mass Spring networks are commonly used to produce simu lations of deformable bodies for computer animation However such an approach can produce inaccurate results if too coarse a discretisation is employed and so many animators use excessively large and slow net works In order to remove the guesswork from such an approach this paper presents a mechanism for adaptively re ning portions of such sys tems to a required accuracy thereby producing more pleasing results at a reduced computational cost Following a discussion of the use of such an approach in simulating a deformable sheet we present several character istic examples to demonstrate its suitability
