What are some tessellation techniques in C++ graphics programming?

Tessellation techniques in C++ graphics programming include flat tessellation, adaptive tessellation, and displacement mapping. Each technique has its own use cases and benefits.

Can you explain flat tessellation in more detail?

Flat tessellation involves dividing a surface into smaller polygons, typically triangles, to create a mesh. This technique is straightforward and is often used for simple shapes.

What about adaptive tessellation?

Adaptive tessellation adjusts the level of detail based on the viewer's distance or angle, providing more detail where needed and optimizing performance.

How does displacement mapping work?

Displacement mapping modifies the position of vertices based on a texture, allowing for complex surface details without increasing the polygon count.
