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 this program code is executed directly on the graphic card of the PC, which allows for more optimal use of the resources of your computer.

“WebGL” is an API on “JavaScript,” used to render interactive 2D and 3D graphics inside HTML5 elements
