Abstract:
Coons surfaces ensure deformation of headlamp reflectors with rigid boundaries. To simplify the shape adjustment of surfaces, Bernstein base function is used to build cross-boundary derivatives. The shape of the surfaces are then determined by 4 given vectors, to which the 4 cross-boundary derivatives approximate. A controller including 3 scalars is put forward to further simplify the shape adjustment of Coons surfaces, which is independent of the position of the surfaces. The 3 scalars, which are function of the 4 approximated vectors and 4 corner position vectors of a Coons surface, control the depth and bias of the concave respectively. Manipulating the 3 scalars can easily change the shape of headlamp reflectors, which is represented in Coons patches with rigid boundaries.
