Class TCastlePunctualLight
Unit
Declaration
type TCastlePunctualLight = class(TCastleAbstractLight)
Description
Ancestor class for all punctual lights: point, spot, directional.
The name "punctual" follows the glTF terminology, https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_lights_punctual . Punctual lights are infinitely small points that emit light from simple position or direction. This makes them different e.g. from area lights, of environment lights.

Cast shadows from this light. Right now this property activates shadow volumes. Please consult the shadow volumes documentation about important requirements of this technique, namely: models that cast shadows must be 2-manifold. Moreover, right now, only one light in the world can cast shadows using shadow volumes. In the future we want to offer a choice between using shadow volumes and shadow maps. | |
