InterleavedBufferAttribute

Constructor​

InterleavedBufferAttribute​

function InterleavedBufferAttribute( interleavedBuffer: InterleavedBuffer,
itemSize: Integer, offset: Integer, normalized: Boolean ): void;

Properties​

data​

data: InterleavedBuffer;

The InterleavedBuffer instance passed in the constructor.

array​

array: TypedArray;

The value of data.array.

count​

count: Integer;

The value of data.count. If the buffer is storing a 3-component item (such as a position, normal, or color), then this will count the number of such items stored.

isInterleavedBufferAttribute​

isInterleavedBufferAttribute: Boolean;

Read-only flag to check if a given object is of type InterleavedBufferAttribute.

itemSize​

itemSize: Integer;

How many values make up each item.

name​

name: String;

Optional name for this attribute instance. Default is an empty string.

needsUpdate​

needsUpdate: Boolean;

Default is false. Setting this to true will send the entire interleaved buffer (not just the specific attribute data) to the GPU again.

normalized​

normalized: Boolean;

Default is false.

offset​

offset: Integer;

The offset in the underlying array buffer where an item starts.

Methods​

applyMatrix4​

function applyMatrix4( m: Matrix4 ): this;

Applies matrix m to every Vector3 element of this InterleavedBufferAttribute.

applyNormalMatrix​

function applyNormalMatrix( m: Matrix3 ): this;

Applies normal matrix m to every Vector3 element of this InterleavedBufferAttribute.

transformDirection​

function transformDirection( m: Matrix4 ): this;

Applies matrix m to every Vector3 element of this InterleavedBufferAttribute, interpreting the elements as a direction vectors.

getZ​

function getZ( index: Integer ): Number;

Returns the z component of the item at the given index.

getW​

function getW( index: Integer ): Number;

Returns the w component of the item at the given index.

setX​

function setX( index: Integer, x: Float ): this;

Sets the x component of the item at the given index.

setY​

function setY( index: Integer, y: Float ): this;

Sets the y component of the item at the given index.

setZ​

function setZ( index: Integer, z: Float ): this;

setXY​

function setXY( index: Integer, x: Float, y: Float ): this;

Sets the x and y components of the item at the given index.

setXYZ​

function setXYZ( index: Integer, x: Float, y: Float, z: Float ): this;

Sets the x, y and z components of the item at the given index.

setXYZW​

function setXYZW( index: Integer, x: Float, y: Float, z: Float, w: Float ):
this;
