ITPEC FE Morning October 2020 Question 24
ITPEC FE Morning October 2020 — Question 24 of 80
Anti-aliasing — smoothing jagged edges on slanted lines displayed on a screen.
Anti-aliasing works by blending intermediate color values along the boundary of a line to reduce the staircase ("jagged") effect caused by discrete pixels.
Why not others:
- (b) Bump mapping — simulates surface relief on 3D objects using normal maps
- (c) Shading — calculates light and shadow on 3D surfaces
- (d) Texture mapping — wraps a 2D image onto a 3D surface
Key rule: "Jagged edge" + "smoothed" = anti-aliasing.
