ShaderBindings class final

A map rather than a generated struct, because the binding contract is by name: the engine writes bindUniformBlock(shader, 'FragInfo', {...}) and a backend looks the members up. A Dart shader does the same lookup.

Constructors

ShaderBindings(Map<String, Map<String, Float32List>> blocks, Map<String, BoundTexture> textures, {Map<String, ByteData> storage = const <String, ByteData>{}, Map<String, CpuStorageTexture> storageTextures = const <String, CpuStorageTexture>{}})

Bindings that look each member up afresh on every read; see ShaderBindings.forDraw for the caching form a draw uses.

const

ShaderBindings.forDraw(Map<String, Map<String, Float32List>> blocks, Map<String, BoundTexture> textures, {Map<String, ByteData> storage = const <String, ByteData>{}, Map<String, CpuStorageTexture> storageTextures = const <String, CpuStorageTexture>{}})

The same bindings, remembering what read finds.

Properties

blocks → Map<String, Map<String, Float32List>>

Block name to member name to floats, exactly as the engine wrote them.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

storage → Map<String, ByteData>

Storage buffers a render stage was handed by name — PassEncoder.bindStorageBuffer. The bytes themselves, a bound range of the buffer: a stage that writes them writes the buffer. Empty for every draw that binds none.

final

storageTextures → Map<String, CpuStorageTexture>

Storage textures a render stage was handed by name — PassEncoder.bindStorageTexture.

final

textures → Map<String, BoundTexture>

Sampler slot name to what is bound there, with the sampler it came with.

Methods

mat4(String block, String member, {int at = 0}) → Matrix4

member of block as a matrix, or the identity.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

read(String block, String member) → Float32List?

member of block, or null if the engine did not write it.

toString() → String

A string representation of this object.

inherited

vec4(String block, String member, Vector4 fallback, {int at = 0}) → Vector4

member of block as a vector, or fallback.

Operators

operator ==(Object other) → bool

The equality operator.
