Which of the following statements is/are True regarding the solution of 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
option B is correct
pls refer

S1 is false, painter algorithm sorts polygons by depth, and then paints the farthest polygon first.
S2 is true, backface curling don't render the curves, which are backface, and not visible. So, it enhances the rendering time.
Option 2
For S1 Statement :
So According To Above Paragraph The Option S1 Is False...
For S2 Statement :
So According To Above Paragraph The Option S2 Is True...
