NodeMaterialObserver
This class is used by WebGPURenderer as management component. It's primary purpose is to determine whether render objects require a refresh right before they are going to be rendered or not.
Constructor
new NodeMaterialObserver( builder : NodeBuilder )
Constructs a new node material observer.
builder
The node builder.
Properties
.hasAnimation : boolean
Whether the node builder's 3D object is animated or not.
.hasNode : boolean
Whether the material uses node objects or not.
.refreshUniforms : Array.
A list of all possible material uniforms
.renderId : number
Holds the current render ID from the node frame.
Default is 0.
.renderObjects : WeakMap.
A node material can be used by more than one render object so the monitor must maintain a list of render objects.
Methods
.containsNode( builder : NodeBuilder ) : boolean
Returns true if the node builder's material uses node properties.
builder
The current node builder.
Returns: Whether the node builder's material uses node properties or not.
.equals( renderObject : RenderObject, lightsData : Array. ) : boolean
Returns true if the given render object has not changed its state.
renderObject
The render object.
lightsData
The current material lights.
Returns: Whether the given render object has changed its state or not.
.firstInitialization( renderObject : RenderObject ) : boolean
Returns true if the given render object is verified for the first time of this observer.
renderObject
The render object.
Returns: Whether the given render object is verified for the first time of this observer.
.getAttributesData( attributes : Object ) : Object
Returns an attribute data structure holding the attributes versions for monitoring.
attributes
The geometry attributes.
Returns: An object for monitoring the versions of attributes.
.getLights( lightsNode : LightsNode, renderId : number ) : Array.
Returns the lights for the given lights node and render ID.
lightsNode
The lights node.
renderId
The render ID.
Returns: The lights for the given lights node and render ID.
.getLightsData( materialLights : Array. ) : Array.
Returns the lights data for the given material lights.
materialLights
The material lights.
Returns: The lights data for the given material lights.
.getMaterialData( material : Material ) : Object
Returns a material data structure holding the material property values for monitoring.
material
The material.
Returns: An object for monitoring material properties.
.getRenderObjectData( renderObject : RenderObject ) : Object
Returns monitoring data for the given render object.
renderObject
The render object.
Returns: The monitoring data.
.needsRefresh( renderObject : RenderObject, nodeFrame : NodeFrame ) : boolean
Checks if the given render object requires a refresh.
renderObject
The render object.
nodeFrame
The current node frame.
Returns: Whether the given render object requires a refresh or not.
.needsVelocity( renderer : Renderer ) : boolean
Returns true if the current rendering produces motion vectors.
renderer
The renderer.
Returns: Whether the current rendering produces motion vectors or not.
