What are some advanced techniques in OpenGL?

Advanced techniques in OpenGL include shadow mapping, screen space reflections, and tessellation. Would you like to dive deeper into any of these?

Can you explain shadow mapping?

Sure! Shadow mapping is a technique used to create realistic shadows in 3D graphics. It involves rendering the scene from the light's perspective to create a depth map, which is then used to determine whether a pixel is in shadow.

What about tessellation?

Tessellation is the process of subdividing polygons into smaller ones to create more detailed surfaces. In OpenGL, this is done using tessellation shaders, which allow for dynamic level of detail.

How do I implement screen space reflections?

To implement screen space reflections, you need to render the scene to a texture, then use that texture to calculate reflections based on the camera's view. This involves ray tracing techniques to determine what is visible.
