MorphedSkinnedGeometry class Geometry

Skinned geometry with morph targets, blended before the skin matrix is applied on both paths.

A skinned morphed draw spends two vertex-stage samplers (the joints texture plus the morph texture). With the 15-sampler lit fragment stage that totals 17 combined units, one over the GLES 3.0 minimum of 16, so a driver at the bare minimum cannot bind a lit skinned morphed draw (real GLES3 hardware reports 32 or more). TODO(morph-sampler-budget): pack the joint matrices and morph deltas into one vertex-stage texture to fit the GLES minimum.

Constructors

MorphedSkinnedGeometry(MorphTargetData morphTargets)
Creates skinned geometry morphed by morphTargets.

Properties

bindsModelTransformInstance → bool
Whether the color encoder should bind the node's model transform as a one-element instance-rate buffer at the slot after this geometry's vertex streams.
no setterinherited
defaultVertexLayout → VertexLayoutDescriptor?
The layout this geometry kind uses when the caller supplies none. Subclasses that describe their vertices override this.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isReadable → bool Geometry
Whether this geometry retains CPU-side vertex data, making extractMeshData available.
no setterinherited
localBoundingSphere → Sphere?
Local-space bounding sphere paired with localBounds. Same nullability semantics.
no setterinherited
localBounds → Aabb3?
Local-space axis-aligned bounding box of this geometry's vertex positions, or null if bounds are unknown. Computed by uploadVertexData for procedural geometry, populated from baked scene-package bounds for imported geometry, and (for the advanced setVertices path where the caller manages its own GPU buffer) left null unless the caller assigns it via setLocalBounds.
no setterinherited
materialVertexVariant → String
The .fmat vertex-variant key for this geometry's mesh type, used to select a custom material's generated vertex shader (see Material.materialVertexShader). Unskinned geometry is 'unskinned'; SkinnedGeometry overrides this to 'skinned'.
no setterinherited
morphTargets → MorphTargetData Geometry
The morph target deltas this geometry carries, or null for unmorphed geometry. Overridden by the morphed geometry subclasses.
no setterinherited
primitiveType ↔ PrimitiveType
How the vertex/index data is assembled into primitives when drawn.
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
usesGpuMorphing → bool
Whether this geometry blends on the GPU (the deltas fit the guaranteed texture dimensions) or falls back to CPU blending.
no setterinherited
vertexShader → Shader
The vertex shader used when rendering this geometry.
no setterinherited

Methods

bind(RenderPass pass, TransientWriter transientsBuffer, Matrix4 modelTransform, Matrix4 cameraTransform, Vector3 cameraPosition, {Shader? shaderOverride, double depthBias = 0.0}) → void
Binds vertex/index buffers and per-frame uniforms onto pass in preparation for a draw call.
override
draw(RenderPass pass, {int instanceCount = 1}) → void
Emits this geometry's draw call after bind has prepared the render pass.
inherited
extractMeshData() → MeshData Geometry
Copies this geometry's retained CPU vertex/index data out as an isolate-transferable MeshData snapshot.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setCustomAttribute(String name, Float32List data, {required int components}) → void Geometry
Attaches a custom per-vertex attribute stream named name, matching a material's attributes entry (and the generated shader's in <name>).
inherited
setIndices(BufferView indices, IndexType indexType) → void
Binds an already-uploaded index buffer view, with element width determined by indexType.
inherited
setJointsTexture(Texture? texture, int width) → void
Hook for skinned geometries to receive the joints texture computed by Skin.getJointsTexture.
inherited
setLocalBounds(Aabb3? aabb, Sphere? sphere) → void
Override the bounds. Useful for callers driving setVertices from a caller-managed gpu.DeviceBuffer who want to participate in bounds-driven scene queries (e.g. frustum culling).
inherited
setMorphWeights(Float32List? weights) → void
Hook for morphed geometries to receive the owning node's morph weights.
inherited
setVertexLayout(VertexLayoutDescriptor? layout, {bool bindsModelTransform = true}) → void
inherited
setVertexShader(Shader shader) → void
Assigns the vertex shader used when this geometry is drawn.
inherited
setVertexShaderName(String name) → void
Assigns the vertex shader by name from baseShaderLibrary.
inherited
setVertices(BufferView vertices, int vertexCount) → void
Binds an already-uploaded vertex buffer view as this geometry's vertex source.
inherited
toString() → String
A string representation of this object.
inherited
uploadVertexData(ByteData vertices, int vertexCount, ByteData? indices, {IndexType indexType = gpu.IndexType.int16}) → void
Allocates a gpu.DeviceBuffer and uploads vertices (and optional indices) into it in one step.
