This paper presents a study for defining the levels-of-detail (LOD) in point-based computational mechanics in haptic rendering of objects. The approach uses the description of object as a set of sampled points. In comparison with the finite element method (FEM), point-based approach does not rely on any predefined mesh representation and depends on the point representation of the object. Different from solving the governing equations of motion representing the entire object based on pre-defined mesh representation which is used in FEM, in point-based modeling approach, the number of points involved in the computation of displacement/deformation can be adaptively re-defined during the solution cycle. This frame work can offer an implementation for the notion of LOD techniques for which can be used to tune the haptic rendering environment for increased realism and computational efficiency. This paper presents some initial experimental studies in implementing LOD in such environment.
