Skin class base Geometry

A skeletal binding used by skinned meshes for animation.

A Skin pairs an ordered list of joints (scene-graph Nodes acting as bones) with the inverseBindMatrices that transform a mesh from model space into each joint's rest-pose local space. The vertex shader combines these with the joints' current transforms to deform the mesh.

Skin instances are usually populated by an importer rather than constructed directly. They are attached to the mesh-bearing Node via Node.skin.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

inverseBindMatrices → List<Matrix4>

The inverse bind matrix for each joint, transforming a vertex from model space into the joint's rest-pose local space.

final

joints → List<Node?>

The bone nodes referenced by this skin, in shader-binding order.

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

flushJointsUpload() → void

Uploads the matrices the last getJointsTexture computed, if they are not uploaded yet. On Vulkan an upload is a synchronous submit that waits for the GPU backlog, so the scene runs it only for frames that draw.

getJointsTexture() → Texture

Computes the joint matrices for the current frame into the next ring slot and returns that slot's square RGBA32F GPU texture. The upload waits for flushJointsUpload, so a frame that draws nothing (one that re-presents its previous image) never pays for it.

getPreviousJointsTexture() → Texture

The previous frame's joints texture from the ring, or the current texture on the first frame.

getTextureWidth() → int

The edge length, in texels, of the joints texture produced by getJointsTexture.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

operator ==(Object other) → bool

The equality operator.
