Point Light [3PL]
The PointLight node
Point Light Node Introduction
A point light is a light source with a clear position in space that emits light in all directions.
A light bulb is a good example of a point light.
This light shows an onscreen control, although only the position and distance of the control
affect the light. Since the light is a 360-degree source, rotation has no meaning. Additionally,
a point light may fall off with distance, unlike an ambient or directional light.
Similar to a Camera 3D, you connect lights into a Merge 3D and view them in the scene by
viewing the Merge 3D node. Selecting a light node and loading it into the viewer does not
show anything.
Inputs
The Point Light node includes a single optional orange input for a 3D scene or 3D geometry.
–
SceneInput: The orange input is an optional input that accepts a 3D scene. If a
scene is provided, the Transform controls in this node apply to the entire scene
provided.
Basic Node Setup
The Point Light node is designed to be part of a larger 3D scene. You connect the light directly
into a Merge 3D. Separating lights into different Merge 3D nodes allows you to control which
lights affect which objects.
