Line class

Line class

A polyline is a path defined by a set of points with Geometry.control_points, and connected by Line.segments, which means it can also be a set of connected line segments. The line is usually a linear object, which means it cannot be used to represent a curve, in order to represent a curve, uses NurbsCurve.

Inheritance: Line → Curve → Entity → SceneObject → A3DObject

The Line type exposes the following members:

Constructors

ConstructorDescription
initInitializes a new instance of the Line class.
initInitializes a new instance of the Line class.

Properties

PropertyDescription
nameGets or sets the name.
propertiesGets the collection of all properties.
sceneGets the scene that this object belongs to
parent_nodesGets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing
excludedGets or sets whether to exclude this entity during exporting.
parent_nodeGets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes.
colorGets or sets the color of the line, default value is white(1, 1, 1)
visibleGets or sets if the geometry is visible
segmentsGets the segments of the line

Methods

MethodDescription
remove_propertyRemoves a dynamic property.
remove_propertyRemove the specified property identified by name
get_propertyGet the value of specified property
set_propertySets the value of specified property
find_propertyFinds the property.
It can be a dynamic property (Created by CreateDynamicProperty/SetProperty)
or native property(Identified by its name)
get_bounding_boxGets the bounding box of current entity in its object space coordinate system.
get_entity_renderer_keyGets the key of the entity renderer registered in the renderer
from_pointsConstruct a Line instance from a set of points.
make_default_indicesGenerate the sequence 0,1,2,3….Geometry.control_points.Length-1 to Line.segments so the ControlPoints can be used as a single line
