Create a buffer to be used as an element array buffer.
Parameters
- context: Context
  The rendering context.
- Optionaldata:
      | number
      | Uint8Array<ArrayBufferLike>
      | Uint16Array<ArrayBufferLike>
      | Uint32Array<ArrayBufferLike>
  The initial data contained in this buffer or the size of this buffer's data store in bytes.
- Optionalusage: BufferUsage
  The intended usage of the buffer.
- Optionaloffset: number
  The index of the element to start reading the initial data at.
- Optionallength: number
  The length of the initial data to read into the buffer.
Returns ElementBuffer
Throws
UnsupportedOperationError if a buffer cannot be created.

- Defined in src/core/buffers/Buffer.ts:136

type

get type(): DataType
The type of the data in this buffer.

Returns DataType

- Defined in src/core/buffers/Buffer.ts:125

usage

get usage(): BufferUsage
The intended usage of this buffer.

Returns BufferUsage

Methods

delete

delete(): void
Delete this buffer.

Returns void

Inherited from Buffer.delete
- Defined in src/core/buffers/Buffer.ts:258

setData

setData(data: number, usage?: BufferUsage): void
Set the size of this buffer, clearing its data.
Parameters
- data: number
  The data to store in this buffer or the size to set this buffer's data store to in bytes.
- Optionalusage: BufferUsage
  The intended usage of the buffer.
Returns void

setData(
    data:
        | VertexBuffer
        | Uint8Array<ArrayBufferLike>
        | Uint16Array<ArrayBufferLike>
        | Uint32Array<ArrayBufferLike>,
    usage?: BufferUsage,
    srcOffset?: number,
    length?: number,
    dstOffset?: number,
): void
Replace all of or update a subset of the data in this buffer.
Parameters
- data:
      | VertexBuffer
      | Uint8Array<ArrayBufferLike>
      | Uint16Array<ArrayBufferLike>
      | Uint32Array<ArrayBufferLike>
  The data to store in this buffer or the size to set this buffer's data store to in bytes.
- Optionalusage: BufferUsage
  The intended usage of the buffer.
- OptionalsrcOffset: number
  The index of the element to start reading the supplied data at.
- Optionallength: number
  The length of the supplied data to read.
- OptionaldstOffset: number
  The offset in bytes to start replacing data at. If this value is set, a subset of the data in the buffer is updated rather than replacing all of the data in the buffer and the usage pattern of the buffer is not updated.
