ShadowDepthShader class final

shadow_depth.frag: window depth into a colour target.

A colour target rather than the depth buffer because flutter_gpu gives no way to sample a depth texture, and the workaround is in the engine rather than in any one backend. gl_FragCoord.z is the right value because the shadow camera is orthographic — under perspective it would be hyperbolic, all its precision near the near plane, and comparing two of them would mean nothing.

Constructors

ShadowDepthShader()

Keeps no state, so one const instance serves every draw; builtinCpuShaders files it under ShadowDepth.

const

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

run(Float32List v, ShaderBindings bindings, FragmentContext c) → Vector4?

Returns linear RGBA for attachment zero. Null discards the fragment.

override

toString() → String

A string representation of this object.
