Linear vs Quadratic Lights - Threejs

Example B

Proposed quadratic decay light for threejs

Currently threejs only supports linear or constant decay for point and spot lights. Here we compare the proposed implementation for quadratic decay.

NOTES

  • Output gamma has to be activated for quadratic decay.
  • Output gamma is deactivated for linear decay.

PARAMETERS

  • Main Distance: distance at which the intensity is 1.0 (maximum without saturation)
  • Linear Fade: only for linear decay, sets how far away from the main distance the light fades out completely.
  • Type of Light: spot or point, as defined in threejs.
  • Light Exponent and Light Angle: only applicable to spot lights.
