What are some advanced techniques for texturing and mapping in C++ graphics APIs?

Some advanced techniques include normal mapping, parallax mapping, and texture atlasing. Would you like to dive deeper into any of these?

Can you explain normal mapping and how it enhances textures?

Normal mapping simulates small surface details by altering the surface normals, creating the illusion of depth without adding geometry.

What is texture atlasing and why is it useful?

Texture atlasing combines multiple textures into a single texture map, reducing draw calls and improving performance in rendering.

How does parallax mapping differ from normal mapping?

Parallax mapping adds depth perception by offsetting texture coordinates based on the viewer's angle, creating a more realistic 3D effect.

Are there any tools or libraries that can help with these techniques?

Yes, libraries like OpenGL and DirectX provide built-in support for these techniques, and tools like Blender can help create the necessary textures.
