How can I implement advanced rendering techniques in OpenGL using C++?

You can start by exploring techniques like shadow mapping, screen space reflections, and deferred rendering. Do you have a specific technique in mind?

I'm particularly interested in shadow mapping. How does it work?

Shadow mapping involves rendering the scene from the light's perspective to create a depth map, which is then used to determine shadowed areas during the final render.

What are the steps to implement shadow mapping in my OpenGL project?

First, set up a framebuffer to render the depth map. Then, render your scene from the light's perspective. Finally, use the depth map in your main render pass to apply shadows.

Are there any performance considerations I should keep in mind?

Yes, shadow mapping can be performance-intensive. Consider using techniques like cascaded shadow maps for large scenes or optimizing the resolution of your depth map.
