Methods

getKind() → string

Returns the kind of the VertexBuffer (string).

isUpdatable() → boolean

Boolean : is the VertexBuffer updatable ?

getData() → Nullable<FloatArray>

Returns an array of numbers or a Float32Array containing the VertexBuffer data.

getBuffer() → Nullable<WebGLBuffer>

Returns the WebGLBuffer associated to the VertexBuffer.

getStrideSize() → number

Returns the stride of the VertexBuffer (integer).

getOffset() → number

Returns the offset (integer).

getSize() → number

Returns the VertexBuffer total size (integer).

getIsInstanced() → boolean

Boolean : is the WebGLBuffer of the VertexBuffer instanced now ?

getInstanceDivisor() → number

Returns the instancing divisor, zero for non-instanced (integer).

create(data) → void

Creates the underlying WebGLBuffer from the passed numeric array or Float32Array.

Returns the created WebGLBuffer.

Parameters
