ITPEC FE Morning October 2021 — Question 24 of 80
Clipping in 3D Graphics — identify the definition of clipping in 3D graphics processing.
Clipping is a process that defines a visible window within the display area, discards geometry outside that window, and keeps only the portion that falls inside.
Why not others:
- (a) Shading — applying light/shadow to surfaces for 3D appearance (e.g., Gouraud, Phong)
- (c) Rendering — the final phase of CG production that converts 3D object data into a 2D image on screen
- (d) Anti-aliasing — smoothing jagged edges ("jaggies") caused by limited pixel resolution
Key rule: Clipping = cutting away what's outside the viewport. Think "clip" = "cut."
