- Spot Light
A Point Light is a light source with a clear position in space that emits light in all directions. A lightbulb is a point light, as is the sun, although light from the sun can appear to be ambient due to scattering from the atmosphere.
This light shows an onscreen widget, although only the position of the widget affects the light. Since the light is a 360 degree source the rotation of the widget has no meaning. Unlike both ambient and directional lights, a point light may falloff with distance.
External Inputs
- PointLight.SceneInput
- [ orange, optional ] This input expects 3D scene. If a scene is provided the transform controls in this tool will apply to the entire scene provided.
Controls Tab
When the Enabled checkbox is selected, the point light affects the scene. Clear the checkbox to turn off the light.
Use this standard Color control to set the color of the light.
Use this slider to set the Intensity of the ambient light. A value of .2 indicates 20% percent light.
A point light defaults to No Decay, meaning that its light has equal intensity at all points in the scene. To cause the intensity to falloff with distance, set the Decay Type either to Linear or Quadratic modes.
Transform Tab
The options which appear in this tab determine the position of the geometry created by this tool. Since these controls are identical on all tools that generate geometry, these controls are fully described in the Common 3D Controls section of this documentation.
