RangeNode

RangeNode generates random instanced attribute data in a defined range. An exemplary use case for this utility node is to generate random per-instance colors:

Code Example

const material = new MeshBasicNodeMaterial();
material.colorNode = range( new Color( 0x000000 ), new Color( 0xFFFFFF ) );
const mesh = new InstancedMesh( geometry, material, count );

Constructor

new RangeNode( minNode : Node.<any>, maxNode : Node.<any> )

Constructs a new range node.

minNode | A node defining the lower bound of the range. Default is float().
---|---
maxNode | A node defining the upper bound of the range. Default is float().

Properties

.maxNode : Node.<any>

A node defining the upper bound of the range.

Default is float().

.minNode : Node.<any>

A node defining the lower bound of the range.

Default is float().

Methods

.getConstNode( node : Node ) : Node

Returns a constant node from the given node by traversing it.

node | The node to traverse.
---|---

Returns: The constant node, if found.

.getNodeType( builder : NodeBuilder ) : string

This method is overwritten since the node type is inferred from range definition.

builder | The current node builder.
---|---

Overrides: Node#getNodeType

Returns: The node type.

.getVectorLength( builder : NodeBuilder ) : number

Returns the vector length which is computed based on the range definition.

builder | The current node builder.
---|---

Returns: The vector length.
