ITPEC FE Morning April 2019 Question 25
ITPEC FE Morning April 2019 — Question 25 of 80
Hidden-line / hidden-surface removal — render only the parts visible from a given viewpoint.
The technique determines which surfaces or edges are occluded by other objects and removes them from the final image.
Why not others:
- (a) Shading/lighting — analyzes light source position to compute color and brightness
- (b) Clipping — crops the image to fit the display boundaries
- (d) Wireframe with translucency — renders both surface and interior, opposite of hiding surfaces
Key rule: Hidden-surface removal = "only draw what the camera can see." Classic algorithms: Z-buffer, painter's algorithm.
