SceneManager

A scene manager for Three.js capable of rendering panorama 360 images and vector data overlays.

  • ol.Object

Members

facesOrder :string

The list of chars for cube face order.

Type:
  • string
Source:
bu-street/scenemanager.js

fovLimitEpsilon :number

A fov of exactly 0 or π breaks some computations, so we constrain it to the [fovLimitEpsilon, π - fovLimitEpsilon] interval. We use 9 decimal places for the epsilon value since this is the maximum number of significant digits for a 32-bit floating-point number. Note that after a certain zoom level, rendering quality will be affected by the loss of precision in floating-point computations.

Type:
  • number
