Defined in: libs/scene/src/material/mixins/lightmodel/lambert.ts:12

Interface of lambert lighting model mixin

Type Declaration

lambertLight()

lambertLight(scope, worldPos, normal, albedo, geometricNormal?): PBShaderExp

Parameters

scope

PBInsideFunctionScope

worldPos

PBShaderExp

normal

PBShaderExp

albedo

PBShaderExp

geometricNormal?

PBShaderExp

Interpolated vertex normal, used for shadow normal offset bias. Defaults to normal; pass the pre-normal-map normal (such as TBN[2]) when the material has one, so the shadow lookup is not displaced along normal map detail.

Returns

PBShaderExp
