The Z-buffer algorithm is used for Hidden surface removal of objects. The maximum number of objects that can be handled by this algorithm shall

  • A.Depend on the application
  • B.be arbitrary no. of objects
  • C.Depend on the memory availability
  • D.Depend on the processor

Answer: B

The Z-buffer algorithm compares the depth of each pixel from every object with the value stored in the buffer, and it handles the objects one at a time, so it does not need to hold or sort all objects. For this reason the number of objects that it can handle is arbitrary, and is not limited by the application, the memory or the processor, which limit only the size of the picture and the speed. The keyed answer is that it can be an arbitrary number of objects.
