## Detailed Description

An uncreatable QML type that provides a WebGL-like API that can be used to draw 3D graphics to the Canvas3D element. You can get it by calling the Canvas3D.getContext method.

See also Canvas3D.

## Property Documentation

canvas : Canvas3D

Holds the read only reference to the Canvas3D for this Context3D.

drawingBufferHeight : int

Holds the current read-only logical pixel height of the drawing buffer. To get the height in physical pixels you need to multiply this with the `devicePixelRatio`.

drawingBufferWidth : int

Holds the current read-only logical pixel width of the drawing buffer. To get the width in physical pixels you need to multiply this with the `devicePixelRatio`.
