What does the WebGL API mean?

This term consists of two main abbreviations.

The first, “ API(“Application Programming Interface”) , is a set of ready-made functions and procedures that are provided by this application and are used in other software products.

The second, “ WebGL ”, is an abbreviation of the English words “Web Based Graphics Library” (translated as “Web-based graphics library”) . This abbreviation means a software library for the JavaScript language, which allows you to create full 2D and 3D graphics in the working window of your browser.

Due to the functional features of such a library, a part of the WebGL program code is executed directly on the graphic card of the PC, which allows for more optimal use of the resources of your computer.
