The area occupied by the surface of a cone is known as the surface area of a cone. The curved surface area of cone refers only to the curved part of the cone which is other than the circular flat base.
The following sections will define the API-level usage and place- ment of the curved PN triangles in the graphics pipeline (Section 2), give a precise derivation of the PN triangle and its properties (Sec- tion 3), and then discuss performance and visual impact to convince the reader that...
1). The two longitudinal edges are tangentially extended to create two symmetric cone surface sections, from now on referred to as the ‘flanges’. The undeformed geometry is parameterized by the width of the flanges, w, the longitudinal and transverse radius, rl,0 and rt,0 and the ...
