Examinishadersshaders Examining the shaders reveals some of the idiosyncrasWebGLf WebGgl The gl_Color keyword is considered invalid. Instead, users must create their own varying vector. Furthermore, a preprocessor statement to set float types to use high precision is also required. These are some examples of changes to the specifications changes which were introduced over time.
'''Typed Arrays'''Performance is always a concern when rendering 3D content, so it was necessary to create a faster versJavaScript'script's inherently slow arrays types. Because of this, typed arrays were incorporated into pre-release versiWebGLf WebGL browsers. Unlike regular arrays which can contain different types such as strings, numbers and objects, typed arrays can only contain one type and cannot by dynamically resized. Some of these types include Float32Intay, Int32Uinty, Uint16ArrUintnd Uint8Array. These types provide a significant performance increase when manipulating arrays.
