Point Operator

Basic Node Parameter

Parameter

Object

This node gives you direct access to an object’s number of points and their positions and point Normals. First create an Object node for the object whose point data you want to access. Click the Object node’s outputs menu (red square) and choose Object from the menu to create an Object port. Connect this Object port to the Point node’s Object port.

Point Index [-2147483648..2147483647]
Point Position [XYZ ]
Point Count [-2147483648..2147483647]
Point Position [XYZ ]

The number of the desired point must be read by the node’s input port. This index number reflects the numbering of the points that can be accessed in the Structure Manager. The number of points of a given object, the points’ locations and the points’ Normals (sum of all adjoining surface Normals) will be made accessible as an output port.

Point Normal

The point normal vector is exactly one unit in length and is always perpendicular to the point. The direction is calculated using the positions of the surrounding surfaces. Hence if the object has no surfaces, the point Normals cannot be calculated accurately.
