Class: MorphTargetData

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:54

GPU-side morph-target (blend-shape) state for a single geometry. Merges per-target position/normal deltas into storage buffers and runs a compute shader each frame to accumulate weighted deltas, then feeds the result into the render shader.

Constructors

Constructor

new MorphTargetData(): MorphTargetData

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:83

Returns

MorphTargetData

Properties

enable

enable: boolean

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:56

Whether morph-target processing is active.

---

morphTargetsRelative

morphTargetsRelative: boolean

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:58

When true, target deltas are applied relatively (added on top of the base).

---

MaxMorphTargetCount

readonly MaxMorphTargetCount: number = 64

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:60

Maximum number of morph targets supported per geometry.

Accessors

blendShape

Get Signature

get blendShape(): object

Defined in: src/components/anim/morphAnim/MorphTargetData.ts:154

Map of blend-shape name to its influence-setter function.

Returns

object
