In this work, a system for 3D sketching is presented. Instead of trying to process 3D data as geometric models constructed of surfaces or solids, the data is stored as 3D lines, preserving their form exactly as entered by the user. The 3D input of the system works by projecting 2D input from a single viewpoint to a grid surface that can be manipulated in(More)
In this paper, a novel algorithm for rendering antialiased 2D polygons is presented. Although such algorithms do exist, they are inefficient when comparing to non-antialiased alternatives. This has lead to a situation where the developers — and the end users of the applications — need to make a choice between high speed and high quality. The algorithm(More)
