FatLineBufferGeometry

This is a dedicated geometry for FatLineSegments .

CoreClass

This is a dedicated geometry for FatLineSegments .

Hierarchy

userData: Record<keyof any, any>

__topologyMark

__topologyMark: TriangleList
name: string

The name of viewer, which could be empty.

isBufferGeometry: boolean

Flag to indicate the type of this class. This value should not be changed by user.

parameters: {}

This object is used to record all parameters which are set when instance is initialized. But, change the value of this object may not change the geometry directly.

meshBVH?: MeshBVH

Use BVH to accelerate rendering. This value usually dose not need you to change it, it is built by the engine automatically.

_indexnull

_index: Nullable<IndexBufferAttribute>

Allows for vertices to be re-used across multiple triangles; this is called using "indexed triangles".
and works much the same as it does in Geometry: each triangle is associated with the indices of three vertices.
This attribute therefore stores the index of each vertex for each triangular face.
If this attribute is not set, the renderer assumes that each three contiguous positions represent a single triangle.
This should be set by setIndex| setIndex() to avoid error.

attributes: { [index: string]: BufferAttribute<TypeArray> }

Core data of Geometry such as vertex positions, normals, UVs and color.

It's better to use addAttribute| addAttribute() or setAttribute| setAttribute() to change this.

See BufferAttribute for more details.

drawRange: BufferRange

Determines which part of buffer will be rendered.

_uuid

_uuid: any
uuid: string

_listeners

_listeners: Map<symbol, Listener<never>[]>
isLineSegmentsGeometry: boolean

Used to check type of this or extended instance. This value should not be changed by user.

id: number
isInstancedBufferGeometry: boolean

Used to check type of this or extended instance. This value should not be changed by user.

type: string

The type of this instance.
