A Sweep-Line Algorithm and Its Application to Spiral Pocketing
Monotone chain sweep-line self-intersection spiral pocketing line-offset
2009/8/19
This paper presents an efficient line-offset algorithm for general polygonal shapes with islands. A developed sweeplinealgorithm (SL) is introduced to find all self-intersection points accurately and ...

Terrain rendering ROAM Implicit coordinates method Culling techniques GIS
2009/8/19
The paper presents an efficient algorithm based on ROAM for visualization of large scale terrain models in realtime. The quality and smoothness of the terrain data visualization within a 3D interactiv...
An Algorithm for Splitting a Box by a Loop and Its Applications in Manufacturing
Tool design Rapid Prototyping (RP) Parting surface Parting line Parting direction
2009/8/19
During the design of dies and molds, the cavity of the object is obtained by subtracting it from a surrounding rectangular block. This box is subsequently split into two halves by the parting surface....
A New Algorithm to Calculate the Optimal Inclination Angle for Filling of Plunge-milling
Plunge-milling Plungers Optimal Inclination Angle Residual Volume
2009/8/19
residual volume (inaccessible volume by the plungers) is minimized when selecting a specific direction of filling. This direction is known as the optimal inclination angle for filling of the plunged a...
