MeshAttributeAccessor

MeshAttributeAccessor 

An iterator over a mesh vertex attribute

Kind: global class

• MeshAttributeAccessor
  • .createArray(count) ⇒ Uint8Array | Uint16Array | Uint32Array | Int32Array | Float32Array
  • .get(i, out)
  • .set(i, v) ⇒ MeshAttributeAccessor

.createArray (count) ⇒ Uint8Array | Uint16Array | Uint32Array | Int32Array | Float32Array 

Create a new TypedArray to hold this attribute values.

This method is useful to create a view to hold the data to pass to MeshAttributeAccessor.get and MeshAttributeAccessor.set

Example:

1
2
3
4
5

const vertexCount = 4;
const positionAttribute = mesh.attribute(MeshAttributes.Position);

// A position has 3 floats per vertex. Thus, positions has length 3 * 4.
const positions = positionAttribute.createArray(vertexCount);

Kind: instance method of MeshAttributeAccessor
Returns: Uint8Array | Uint16Array | Uint32Array | Int32Array | Float32Array - A TypedArray with the appropriate format to access the data

.get (i, out) 

Get attribute element

Kind: instance method of MeshAttributeAccessor

.set (i, v) ⇒ MeshAttributeAccessor 

Set attribute element

Kind: instance method of MeshAttributeAccessor
Returns: MeshAttributeAccessor - Reference to self (for method chaining)
