The Rolling Ball
Interactive graphics systems often need techniques that allow the user to rotate graphical objects freely in three-dimensional space using commonly-available two-dimensional input devices such as a mouse. Achieving this goal is hampered by the fact that there is no single natural mapping from the two parameters of the input device to the three-parameter space of orientations. Here we i n troduc...
متن کاملBlending Operations Using Rolling-Ball Filleting
Blending sharp edges in solid models is an important task of Computeraided design. The prominent algorithms for producing blending fillet surfaces relay mostly on the rolling-ball method. These algorithms are applied on B-Rep solid models that are used in many CAD/CAM systems. Such solid models allow for a hierarchical approach of modeling which can incorporate blending operations within its st...
متن کاملG 2 and the Rolling Ball
Understanding the exceptional Lie groups as the symmetry groups of simpler objects is a longstanding program in mathematics. Here, we explore one famous realization of the smallest exceptional Lie group, G2. Its Lie algebra g2 acts locally as the symmetries of a ball rolling on a larger ball, but only when the ratio of radii is 1:3. Using the split octonions, we devise a similar, but more globa...
متن کاملGraphics-assisted Rolling Ball Method for 5-axis surface machining
In this paper, a graphics hardware-assisted approach to 5-axis surface machining is presented that builds upon a tool positioning strategy named the Rolling Ball Method presented in an earlier paper by the present authors [Comput. Aided Des. 35 (2003) 347]. The depth buffer of the computer’s graphics card is used to compute the data needed for the Rolling Ball Method, which generates gouge-free...
متن کاملRolling ball method for 5-axis surface machining
Curvature matching for 5-axis surface machining has been plagued by the complexity of the task. As a result the current tool positioning strategies are likewise computationally complicated. Gouging the surface has been the main concern and has presented the greatest dif®culty in the algorithms. Some of the methods perform exhaustive searches of the surface to avoid gouging while others incremen...
