What is deferred shading optimization in C++?

Deferred shading optimization is a rendering technique that improves performance by separating scene geometry from lighting calculations.

How does it differ from traditional shading methods?

Unlike traditional methods that calculate lighting per object, deferred shading calculates lighting in a separate pass, allowing for more complex scenes.

What are the benefits of using deferred shading?

The main benefits include better performance with many light sources, reduced overdraw, and more flexibility in material properties.

Are there any downsides to using this technique?

Yes, downsides include increased memory usage for G-buffers and potential issues with transparency and anti-aliasing.

Can you give an example of how to implement it in C++?

Sure! You would typically set up G-buffers to store geometry data, then perform lighting calculations in a separate shader pass.
