"Interleaved" means that multiple types of data (position, color etc.) are packed into a single array buffer.
Organizing geometry data in this way improves memory locality. By keeping vertex data close together, it is more likely
that also caches (e.g. pre-transform vertex cache) store logically related data together. This leads to more cache hits and a better performance.
"Interleaved" means that multiple attributes, possibly of different types, (e.g., position, normal, uv, color) are packed into a single array buffer.
