SkinnedGeometry class Geometry

Geometry whose vertices use the skinned 80-byte layout: the unskinned attributes followed by 4 joint indices and 4 joint weights.

Used for meshes attached to a Skin for skeletal animation. The joints texture supplied by the skin must be assigned before each draw via setJointsTexture.

Constructors

SkinnedGeometry()

Creates a SkinnedGeometry preconfigured with the SkinnedVertex shader from baseShaderLibrary.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

localBoundingSphere → Sphere?

Local-space bounding sphere paired with localBounds. Same nullability semantics.

no setter, inherited

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 setter, inherited

primitiveType ↔ PrimitiveType

How the vertex/index data is assembled into primitives when drawn.

getter/setter pair, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

vertexShader → Shader

The vertex shader used when rendering this geometry.

Methods

bind(RenderPass pass, HostBuffer transientsBuffer, Matrix4 modelTransform, Matrix4 cameraTransform, Vector3 cameraPosition) → 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

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

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.

override

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

setVertexShader(Shader shader) → void

Assigns the vertex shader used when this geometry is drawn.

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.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
