ABSTRACT
This chapter describes an application in 2D which is easily expandable to a 3D computer graphics application: computing the visibility of bounded spheres related to a view cone (see Sect. 15.7). In this chapter, we lay the foundations in 2D, computing the visibility of bounded circles compared to a 2D view cone. Is a circle outside a 2D cone modeled by circles? https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315152172/05b92b15-682a-4737-aabb-5365e4b7c38b/content/fig11_1_B.jpg"/>
