A VRML point is a dot located within a VRML world. To locate the exact location of a point, it is necessary to give the coordinate of that point. Coordinate node allow to define 3-D coordinates:
-
Coordinate { point [] # exposedField MFVec3f }

| 2 |
Coordinate node can be used any coord field of PointSet, IndexedLineSet, or IndexedFaceSet node.
|
| 3 |
Each value of point field contains three floating-point number.
|
| 4 |
The first value in the point array is indexed as 0th component.

set_point and point_changed events are implied because of exposedField definition. These allow one to move/animate points
