When computer generated pictures or images are of a mosaic of geometrical shapes, it is called
(A) Cell
(B) stop-frame animation
(C) Serrated outline
(D) Sketching
Correct Ans: (C)
Explanation:
Computer-generated images develop serrated outlines when designers create visuals using a mosaic of geometric shapes. These outlines appear as jagged or rough edges, especially in low-resolution graphics, early animations, and pixel-based images. Small square pixels fail to form perfect curves, which makes images look pixelated.
Designers construct images using geometric patterns, particularly in vector graphics and 3D modeling. When they work with low resolution or fail to apply anti-aliasing, images develop serrated outlines. To fix this issue, they use higher resolutions, anti-aliasing techniques, or smoothing filters to create sharper visuals.
The other options do not describe this effect accurately. “Cell” (Option A) refers to individual frames in traditional animation. “Stop-frame animation” (Option B) describes a motion technique where creators move objects slightly between frames. “Sketching” (Option D) involves freehand drawing, unrelated to pixelated edges in digital graphics.
In conclusion, serrated outlines result from low resolution and a lack of smoothing techniques. Modern advancements in computer graphics have significantly reduced this issue, helping designers produce sharper and more realistic images.
