Application of Bezier Curves For Pressure Sensitive Drawing Applications
DEMAIS is an electronic sketching tool useful for designing interactive multimedia applications. The tool enables a designer to sketch an idea that involves time-based or interactive behavior. This enables a designer to directly interact with the idea instead of the traditional method of using storyboard and envisioning the idea. The idea of the computer aided sketching is the basis of this research. As a part of the tool, a designer draws strokes. These strokes are represented using the X, Y coordinate pairs. The problem with the vector curve is that as the magnification increases the edges of the curves are noticeable. A Bezier curve produces an infinitely smooth curve, meaning that at any magnification there are no edges in the drawn curve. This may seem insignificant at first, but when the action is zoomed in upon multimedia the possibility of seeing these edges is high. With such high technology available to produce benchmark graphics, it would seem rather poor to have pronounced edges. Bezier curves are a type of spline, and all splines are actually mathematical expressions of a curve. The use of a Bezier curve would provide the artist with a smoother, and more efficient computer model.
