Which of the following statements is/are True regarding the solution to the visibility problem in 3D graphics ?
S1 : The Painter’s algorithm sorts polygons by depth and then paints (scan - converts) each Polygon on to the screen starting with the most nearest polygon.
S2 : Backface Culling refers to eliminating geometry with backfacing normals.
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: B. S2 only
Explanation
The painter's algorithm paints from the farthest polygon to the nearest, so S1 is false. Back-face culling removes polygons whose normals face away (S2 true).
