NodeMaterial: updates and revision

[sunag]

Description

NodeMaterial & WebGPU

• physicallyCorrectLights is default in WebGPURenderer
• Split all BRDFs in individual files
• ToneMappingNode support
  • use renderer.toneMappingNode = new Nodes.ToneMappingNode( ... )
• add FogNode.mix()
• add NodeMaterial.generateOutput() and revision to add IBL soon
• add WebGPUNodeBuilder.getSamplerBias()
• VarNode.op( ... ) support
• add ReflectedLightNode
• update examples

ShaderNode

• ShaderNode( ... ) was deprecated, use ShaderNode.call( .. ) instead of to call a function
• addTo( varNode, ... ) was deprecated, use varNode.add( ... ) instead of
• add context, reflectedLight

NodePlayground

• Update WebGPU and WebGL examples

Can it be just const PhysicalLightingModel = RE_Direct_Physical?

[sunag]

At this moment it make more sense but I will add others functions like RE_IndirectSpecular_Physical soon...

Thanks!

• use scene.toneMappingNode = new Nodes.ToneMappingNode( ... )

Hmm, do you think we should move renderer.toneMapping to scene.toneMapping? 🤔

No, no! I made a mistake in the description only.
