Web 3D refers to interactive 3D technology that one can use through a web browser. 
WebGL (Web Graphics Library) is a JavaScript API for Rendering 3D graphics within any compatible web browser without the use of plug-ins. Modern Web3D pages are commonly powered by WebGL.
3D Computer Graphics  are graphics that use a three-dimensional representation of data that is stored in the computer for the purposes of performing calculations and Rendering 2D images. Such images may be stored for viewing later or displayed in real-time.
