With the viewpoint, we associate an axis-alligned local reference framework. Projections on the XY plane of the local axis and the bisector of the first and third quadrants define six sectors. Specific visiting rules for collections of triangles that project on each sector are then defined. The experiments conducted show that the implementation of a simple algorithm based on the set of visiting rules defined allows real time interaction when the viewing position moves along an arbitrary 3D path.I.3.3 [Computer Graphics]Picture/Image GenerationLine and curve generation10.2312/ceig.2016131343-48
