Properties

OptionaltoneMapping

toneMapping?: ToneMappings

Whether the shading function should apply tone mapping to the resulting color and if so, which one. Default to 'Khronos'.

OptionaladditionalVaryings

additionalVaryings?: { type: string; name: string }[]

Optional additional varyings to pass from the vertex shader to the fragment shader.

Type declaration

  • type: string

    type of the varying.

  • name: string

    name of the varying.

Optionalchunks

chunks?: AdditionalChunks

Additional WGSL chunks to add to the shaders.

geometry

geometry: Geometry

Geometry used to create the fragment shader. Can use the vertexBuffers properties for vertex colors or tangent/bitangent computations.

OptionalmaterialUniform

materialUniform?: BufferBindingBaseParams

The BufferBindingBaseParams holding the material uniform values. Will use default values if not provided.

OptionalmaterialUniformName

materialUniformName?: string

The BufferBindingBaseParams name to use for variables declarations. Default to 'material'.

OptionalreceiveShadows

receiveShadows?: boolean

Whether the shading function should account for current shadows. Default to false.

OptionalextensionsUsed

extensionsUsed?: GLTFExtensionsUsed

The glTF extensions used to generate this fragment shader.

OptionalenvironmentMap

environmentMap?: EnvironmentMap

EnvironmentMap to use for IBL shading.

OptionalbaseColorTexture

baseColorTexture?: ShaderTextureDescriptor

Base color texture descriptor to use if any.

OptionalnormalTexture

normalTexture?: ShaderTextureDescriptor

Normal texture descriptor to use if any.

OptionalemissiveTexture

emissiveTexture?: ShaderTextureDescriptor

Emissive texture descriptor to use if any.

OptionalocclusionTexture

occlusionTexture?: ShaderTextureDescriptor

Occlusion texture descriptor to use if any.

OptionalmetallicRoughnessTexture

metallicRoughnessTexture?: ShaderTextureDescriptor

Metallic roughness texture descriptor to use if any.

OptionalspecularTexture

specularTexture?: ShaderTextureDescriptor

Specular texture descriptor (mixing both specular color in the RGB channels and specular intensity in the A channel) to use if any.

OptionalspecularFactorTexture

specularFactorTexture?: ShaderTextureDescriptor

Specular intensity texture descriptor (using the A channel) to use if any.

OptionalspecularColorTexture

specularColorTexture?: ShaderTextureDescriptor

Specular color texture descriptor (using the RGB channels) to use if any.

OptionaltransmissionTexture

transmissionTexture?: ShaderTextureDescriptor

Transmission texture descriptor to use if any.

OptionalthicknessTexture

thicknessTexture?: ShaderTextureDescriptor

Thickness texture descriptor to use if any.

OptionaltransmissionBackgroundTexture

transmissionBackgroundTexture?: ShaderTextureDescriptor

Transmission scene background texture descriptor to use if any.
