Which of the following is true about z-buffer algorithm?
- A.
It is a depth sort algorithm
- B.
No limitation on total number of objects
- C.
. Comparisons of objects is done
- D.
z-buffer is initialized to background colour at start of algorithm
Attempted by 14 students.
Show answer & explanation
Correct answer: B
The z-buffer algorithm determines visibility by comparing depth values for each pixel on the screen. It does not require sorting objects beforehand, allowing it to handle any number of overlapping objects efficiently. The depth buffer is initialized to maximum depth values, ensuring that closer objects correctly overwrite further ones during rendering.
