PointSet {
SFNode color NULL # {Color, PROTO}
SFNode coord NULL # {Coordinate, PROTO}
}
The PointSet node represents a set of 3D points specified in the coord field.
PointSet nodes don't support PBRAppearance.
Instead, you should use an Appearance node in the Shape containing the PointSet geometry or leave the appearance field to NULL.
PointSet nodes are not lit, not texture-mapped and they do not cast or receive shadows.
PointSet nodes cannot be used for collision detection (boundingObject).
The color field optionally contains a Color node which defines the color of each point.
If the color field is not NULL, the Color node should have the same number of items as the Coordinate node in the coord field.
If the color field is NULL, the emissiveColor of the Material will be used to define the color of the points.
The coord field contains a Coordinate node that specifies the list of 3D points.
