What are some advanced techniques in OpenGL using C++?
Some advanced techniques include shadow mapping, environment mapping, 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.
How do I implement shadow mapping in my C++ OpenGL project?
To implement shadow mapping, you'll need to set up a framebuffer object (FBO) to render the depth map, then use that map in your shader to determine shadowed areas.
What about environment mapping?
Environment mapping simulates reflective surfaces by using a texture that represents the environment. It can be implemented using cube maps for more realistic reflections.
