NURBS are more suited to shapes that have a mathematical basis, such as knots. CSG models are good for the piece-wise modeling of objects from implicit surfaces. (Implicit surfaces are those for when an equation of three variables equal zero, such as planes, spheres, tori, surfaces of ...
Defines a brush of a single color. Brushes are used to fill graphics shapes, such as rectangles, ellipses, pies, polygons, and paths. This class cannot be inherited.
The work of the Greek polymath Plato has kept millions of people busy for millennia. A few among them have been mathematicians who have obsessed about Platonic solids, a class of geometric forms that are highly regular and are commonly found in nature....
