PbrHooks class abstract base

The injection points of the standard model, as a material lit by it (lighting standard;, version 4 of the material language) fills them: lib/pbr.glsl's ShadeSurfaceHook, ShadeLightHook and F3dLightTypeHook, each a method here with the answer of a stage that defines none by default.

Extendable outside this package: flutter3d_app's material stage implements it over a program's blocks.

One context per hook, each a class that can gain members — what the GLSL hook is handed next — without an implementation written against 1.0 breaking. Breaking in 1.0.0-rc.1: they took the GLSL hooks' arguments one by one.

Constructors

PbrHooks()

Hooks that change nothing; a subclass overrides the ones it fills.

const

Properties

hashCode → int

The hash code for this object.

no setter, inherited

readsLightRow → bool

Whether lightType is asked at all: a stage that declares no plugin light and reads no light's row is not.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

light(PbrLightContext context) → Vector3

ShadeLightHook: the answer to PbrLightContext.light, given the model's own PbrLightContext.standard, which it is by default.

lightType(PbrLightTypeContext context) → bool

F3dLightTypeHook: told every light's type code and its row's last vec4 before it is sampled; whether a plugin's light (a code from 16 up) is one the stage lights. The engine's four only, by default.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

surface(PbrSurfaceContext context) → void

ShadeSurfaceHook: rewrites PbrSurfaceContext.surface once its maps are applied, before any light. Leaves it as it is by default.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
