Comparison of Algorithms

• Backface culling fast, but insufficient by itself
• Painter's algorithm device independent, but details tough, and algorithm is slow
• Warnock's algorithm easy to implement, but not very fast, and is semi-device dependent.
• Z-buffer online, fast, and easy to implement, but device dependent and memory intensive. Algorithm of choice for hardware
