ITPEC FE Subject A October 2025 Question 17
ITPEC FE Subject A October 2025 — Question 17 of 60
Anti-aliasing — a technique to smooth jagged edges on slanted lines displayed on screens.
How it works:
- Pixels along diagonal edges get intermediate color values (partial shading)
- This creates the illusion of a smooth line instead of a staircase pattern
Why not others:
- (b) Bump mapping — simulates surface roughness in 3D rendering
- (c) Shading — calculates light and shadow on 3D surfaces
- (d) Texture mapping — applies a 2D image onto a 3D object's surface
Key rule: "Jagged edge" + "smooth appearance" = anti-aliasing.
