THE APPLICATION OF QUADRATIC BEZIER CURVE ON ROTATIONAL AND SYMMETRICAL LAMPSHADE
ABSTRACT: The procedure of
constructing lampshade is through parameter merger and selection of Bezier
surfaces shapeshifters; thus it producesperfect and varied
sitting-lampshades.Constructing sitting-lamp shades requires the study of the
physical (lighting) and geometryaspects. In terms of geometry, the existed
sitting-lampshade creation models is generally monotonous and constructed from
objects pieces. In line with these problems, this research is divided into four
stages:First, preparing the data to build a sitting-lampshade. Second,
technical studying to construct the symmetricity of the sitting-lamp shade
shape.Third, constructing the parts of the sitting-lampshade, namely the base,
the main part, the roof. Fourth, constructingthe complete sitting-lampshade. The
results of this research to obtain the procedures of constructing the
sitting-lampshade namely: First, dividing the major axis into three
non-homogeneous sub segments.Second, constructing parts of the
sitting-lampshade namely the base, the main part, and the roof by combining the
sitting-lamp shade components from the geometrical objects deformation.Third,
filling each sub segment of non-homogeneous parts with parts of the lampshade
and creating the boundary curvesproducing a varied innovative symmetricalmodels
of sitting-lampshade.
