SUMMARY

Raytracers in computer graphics predominantly treat light as particles due to the simplicity of the mathematics involved. This approach is effective because most real-world surfaces are scaled in a way that minimizes edge and slit effects, making wave properties of light less relevant for typical rendering tasks. The discussion highlights that while particle representation suffices for general applications, simulating light from an ant's perspective would require a wave-based approach to capture the nuances of light behavior.

Why do computer graphics programs like raytracers treat light almost exclusively as a particle rather than a wave?

The mathematics is a lot simpler. I speak from experience.
 
And since nearly all surfaces in real life are scaled such that edge and slit effects are not noticeable, it serves little point in accounting for them anyway.

Now, if we wanted to simulate what an ant sees, that would be a different story.
