The Algorithm of Making up Missed Lines for Imperfect Line Drawing
Yilin Chen · Journal of Engineering Graphics · 2007
In 3D line drawing which has hidden lines displayed,a labeling method for imperfect line drawing aiming for searching external contour lines is described.According to 26 relations between L junctions and W,Y junctions,the matched rules and the algorithms of making up missed lines for pairs of junctions are suggested and programmed by VC.The example shows that the algorithm can let the computer simulates the human’s thinking and makes up missed lines for imperfect line drawing effectively.
