Question

These shapes can be efficiently anti-aliased using a prefiltering method developed by McNamara, McCormack, and Jouppi. These shapes are drawn by one of the earliest computer graphics algorithms, made in 1962, that is essentially a fast digital differential analyzer that avoids floating-point operations. OpenGL has namesake LOOP and STRIP primitives for drawing linked instances of this shape. In an SVG, this shape (-5[1])can be drawn with an M command followed by an H, V, or L command. It’s not a circle, (15[1])but Xiaolin Wu developed an anti-aliasing algorithm for this shape that builds on the (*) Bresenham algorithm for drawing it. Bézier (“BEH-zee-ay”) curves with two control points are these shapes. (10[1]-5[1])Connecting (10[1])a series of these shapes results in a chain sometimes called a “poly-[this shape]”. For 10 points, name these basic shapes in computer graphics, which on paper can be drawn with a straightedge. ■END■ (10[2])
