Question

Which of the following is used to create images using mathematical formulae for lines and shapes?

• A. Pixel mapping
• B. Raster graphics
• C. Vector Graphics
• D. Voxel rendering

Hint:

Remember the scaling differences: - Vector Graphics $\rightarrow$ Mathematical equations $\rightarrow$ Infinitely scalable without pixelation (e.g., CAD drawings). - Raster Graphics $\rightarrow$ Fixed pixel grids $\rightarrow$ Blurs or pixelates when magnified (e.g., photographs).

Answer 1

The Correct Option is C

Concept: Digital images are generated using two primary methods: pixel grids or geometric formulas. This distinction dictates how graphics scale and dictates their ideal application in CAD drafting, mapping, and graphic design software. Step-by-step Explanation:
• Analysis of Options (A and B): Raster graphics (and pixel mapping) define images using a rigid grid of colored blocks called pixels (as seen in JPEG or PNG formats). When a raster image is magnified, these pixels stretch, creating visible distortion and blurry edges.
• Analysis of Option (C): Vector graphics define images using mathematical equations and geometric coordinate vectors. Features like lines, curves, circles, and polygons are calculated dynamically based on fixed control points. This allows vector graphics (such as SVG, DWG, or AI formats) to scale infinitely without losing clarity or sharpness, making them the standard choice for architectural CAD drafting and GIS mapping software.
• Analysis of Option (D): Voxel rendering uses three-dimensional volumetric pixels, which are commonly used in medical imaging scans or specialized 3D terrain mapping rather than standard 2D vector layouts. Therefore, graphics built on mathematical shapes and lines are classified as Vector Graphics.
