VaryingNode

Class for representing shader varyings as nodes. Varyings are create from existing nodes like the following:

Code Example

const positionLocal = positionGeometry.toVarying( 'vPositionLocal' );

Constructor

new VaryingNode( node : Node, name : string )

Constructs a new varying node.

node | The node for which a varying should be created.
---|---
name | The name of the varying in the shader. Default is null.

Properties

.global : boolean

This flag is used for global cache.

Default is true.

Overrides: Node#global

.interpolationSampling : string

The interpolation sampling type of varying data.

Default is null.

.interpolationType : string

The interpolation type of the varying data.

Default is null.

.isVaryingNode : boolean (readonly)

This flag can be used for type testing.

Default is true.

.name : string

The name of the varying in the shader. If no name is defined, the node system auto-generates one.

Default is null.

Overrides: Node#name

.node : Node

The node for which a varying should be created.

Methods

.setInterpolation( type : string, sampling : string ) : VaryingNode

Defines the interpolation type of the varying.

type | The interpolation type.
---|---
sampling | The interpolation sampling type Default is null.

Returns: A reference to this node.

.setupVarying( builder : NodeBuilder ) : NodeVarying

This method performs the setup of a varying node with the current node builder.

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

Returns: The node varying from the node builder.
