Pointer

DESCRIPTION

This module draws a 3D arrow at a picked position. The tip of the arrow is at the picked position and, by default, its orientation is along the normal to the surface at the picked position.

Although the module fires for all types of pick events, it only updates the position of the arrow for button down pick events. For each pick event, the module ignores any hits that originate from the arrow geometry itself.

INPUTS

Port: Position
Type: Pick
Input pick port

WIDGETS

Port: Scale
Type: Dial
Scaling parameter for arrow geometry. By default, (Scale = 1) the arrow is one unit long (in world space coordinates).

Port: Flip?
Type: Radio Box
Menu Item: No
Menu Item: Yes
This parameter determines the direction of the arrow. By default (Flip? = No) the arrow is aligned along the direction of the unit normal to the surface at the picked postion; setting Flip? to Yes aligns it against this direction.

Port: Color
Type: Text
Color string used to color the arrow. See cxParamColorFloatGet(3E) for valid color names.

OUTPUTS

Port: Pointer
Type: Geometry
Output arrow geometry Pointer
