Types

Lines (object)

The Lines object implements a Geometry made of line segments. Each segment corresponds to attribute index pairs.

The Lines have a raycastThickness member that defines the lines’ thickness for bounding volume and SpatialQueryable methods.

注釈

For functions treating elements such as SpatialQuery.getElementsInBBox, an element corresponds to a line segment.

Members

GeometryAttributes attributes Container for all attributes.
String debugName Name that will be printed in descriptions.
UInt32 structureVersion Version of the geometry structure itself, excluding the GeometryAttributes content.
Boolean computeGPUBoundingVolume If positions are on the GPU: if true, the bounding volume is computed, else an infinite bbox is returned.
ThreadsafeMetaDataContainer metaData Container for holding various user data (Geometry specific), such as the BoundingBox cache data, or raycast acceleration structures and data (Octree).
UInt32[] indices Point index pairs for segments
Scalar raycastThickness Thickness to be used for SpatialQueryable methods
