LineSet
LineSet is a geometry node that can contain a Color node and a Coordinate node. Color values or a Material emissiveColor is used to draw lines and points. Lines are not lit, are not texture-mapped, and do not participate in collision detection. Hint: use a different color (or emissiveColor) than the background color. Hint: if rendering Coordinate points originally defined for an IndexedFaceSet, index values may need to repeat each initial vertex to close each polygon outline. Hint: insert a Shape node before adding geometry or Appearance.

Interface
Filter: X3D only | Avalon only | All
id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
cacheMode | SFString | initializeOnly | auto | auto; dlist; vbo; off | controls the creation of geo cache objects; auto is vbo or dlist for dynamic objects | |
ccw | SFBool | initializeOnly | TRUE | ccw = counterclockwise: ordering of vertex coordinates orientation. Hint: "ccw" false can reverse solid (backface culling) and normal-vector orientation. | ||
colorPerVertex | SFBool | initializeOnly | TRUE | Whether Color node is applied per vertex (true) or per polygon (false). | ||
creaseAngle | SFFloat | initializeOnly | 0 | [0, Inf) | "creaseAngle" defines angle (in radians) for determining whether adjacent polygons are drawn with sharp edges or smooth shading. If angle between normals of two adjacent polygons is less than "creaseAngle", smooth shading is rendered across the shared line segment. Interchange profile hint: only 0 and radians supported. Hint: creaseAngle=0 means render all edges sharply, creaseAngle=3.14 means render all edges smoothly. | |
loop | SFBool | initializeOnly | FALSE | controls if the line-strip should be open or closed | ||
multiResolutionLevel | SFInt32 | initializeOnly | 1 | resolution level in progressive mesh | ||
normalPerVertex | SFBool | initializeOnly | TRUE | Whether Normal node is applied per vertex (true) or per polygon (false). | ||
normalUpdateMode | SFString | initializeOnly | nice | none; fast; nice | force update of normals; nice update is with creaseAngle, fast is without | |
solid | SFBool | initializeOnly | TRUE | Setting "solid" true means draw only one side of polygons (backface culling on), setting "solid" false means draw both sides of polygons (backface culling off). Warning: default value true can completely hide geometry if viewed from wrong side! | ||
attrib | MFNode | inputOutput | VertexAttribute | If the "attrib" field is not empty it shall contain a list of per-vertex attribute information for programmable shaders | ||
color | SFNode | inputOutput | Color | If NULL the geometry is rendered using the Material and texture defined in the Appearance node. If not NULL the field shall contain a Color node whose colours are applied depending on the value of "colorPerVertex". | ||
coord | SFNode | inputOutput | Coordinate | Coordinate node specifiying the vertices used by the geometry. | ||
fogCoord | SFNode | inputOutput | FogCoordinate | If not NULL, it shall contain a FogCoordinate node. | ||
invalidateVolume | SFBool | inputOutput | FALSE | set volume invalid | ||
lit | SFBool | inputOutput | FALSE | specifies whether to enable/disable lighting the geometry. TRUE enables lighting, FALSE disables lighting. | ||
logFeature | MFString | inputOutput | state, child, parent, route, eventIn, eventOut | controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything | ||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element | ||
normal | SFNode | inputOutput | Normal | If not NULL, it shall contain a Normal node whose normals are applied to the vertices or faces of the geometry. | ||
optimizationMode | MFString | inputOutput | auto | auto; all, none, sharedVertex; stripFan; vertexResort; reduceIndexSize; singleIndex | optimization mode settings; used leading +/- to switch modes on and off | |
resolution | SFFloat | inputOutput | 1 | factor for subdivision of mesh | ||
showNormalLength | SFFloat | inputOutput | 0 | [0, Inf) | Length of normals. If zero (default), normals are not shown. | |
texCoord | SFNode | inputOutput | TextureCoordinateBase | If not NULL, it shall contain a TextureCoordinate node. | ||
vertexCount | MFInt32 | inputOutput | [2,infinity] vertexCount describes how many vertices are used in each polyline from Coordinate field. Coordinates are assigned to each line by taking vertexCount[n] vertices from Coordinate field. |
