    A versatile voxel-based architecture for 3-D volume visualization, called the Cube architecture, is introduced. A small-scale prototype of the architecture has been realized in hardware and has been operating in true real-time, faster than the alternative voxel systems. The Cube architecture is centered around a 3-D cubic frame buffer, of voxels, and it entertains three processors that access the ... View full abstract»

    Two methods are presented for generating Koch curves, analogous to the commonly used iterative methods for producing images of Julia sets. The attractive method is based on a characterization of Koch curves as the smallest nonempty sets closed with respect to a union of similarities on the plane. The repelling method is in principle dual to the attractive one but involves a nontrivial problem of s... View full abstract»

  • Physically based models with rigid and deformable components

    A class of physically based models suitable for animating flexible objects in simulated physical environments was proposed earlier by the authors (1987). The original formulation works as well in practice for models whose shapes are moderately to highly deformable, but it tends to become numerically ill conditioned as the rigidity of the models is increased. An alternative formulation of deformabl... View full abstract»

  • Interactive animation: a language and system for procedural modeling and motion

    A description is given of MML, a special-purpose programming language developed for procedural models. The language is used to specify both the generation of the model and the motion of the objects in the model. A motion specification technique that works well with natural phenomena is presented. It has the advantages of being independent of the detailed structure of the object and lending itself ... View full abstract»

  • Using the bat: a six-dimensional mouse for object placement

    Existing strategies for 6-D placement (i.e positioning and orienting) are briefly reviewed. An approach is presented that uses a 6-D variant on the conventional mouse, called the 'bat', because it is like a mouse that flies. This device encodes relative position, like the mouse, but delivers data in all six dimensions needed for object placement. The goal is to evaluate the bat to determine how we... View full abstract»
