21. Logos are also modified to fit curved surfaces and appear identical from diverse viewing angles. 22. Diagonal flat lock panels are used on curved surfaces , such as domes, spires and vaults. 23. Substrates can be planar surfaces, such as silicon and metals, or curved surfaces , such as nanoparticles. 24. Rather, any mathematical function transforming coordinates from the curved surface to the plane is a projection. 25. A laser can cut into both flat and curved surfaces such as the surfaces on jewellery. 26. This allowed the construction of smooth curved surfaces . 27. Plywood is often used to create curved surfaces because it can easily bend with the grain. 28. Adjustable bowed strips of wood and curved surfaces produce a crisper sound without as much effort. 29. The chapel's Byzantine interior features Guastavino tile vaulting in intricate patterns on almost every curved surface . 30. Other three-dimensional shapes may be bounded by curved surfaces , such as the ellipsoid and the sphere.
