Texture Mapping
Can you live without Textures ? Probably you can 😀 but the fact is a scene without textures is ugly unless you are a very professional developer.
With textures you can add a pattern to surface of an object. imaging a concrete cube, what will you have if remove the concrete texture ? a simple cube . isn’t that right ?
I love using textures for my scenes but we should be careful because in WebGL the texture wrapping method is a little bit confusing for all screen sizes and if you don’t define the right mapping method and size you will get some warnings and lags in browser.
