In rendering optimisation, FRUSTUM CULLING and OCCLUSION CULLING both skip work; the latter additionally rejects which case?
AStatic objects that have never moved
BObjects with alpha = 0 ever drawn
CObjects outside the camera near plane only
DObjects hidden behind closer opaque objects
Answer & Solution
Correct answer: D. Objects hidden behind closer opaque objects
Unity / Unreal docs: frustum culling rejects objects outside the view frustum. Occlusion culling additionally rejects objects blocked by closer geometry.
