Class: Track

Defined in: packages/cal3d/src/Animation.ts:42

Constructors

Constructor

new Track(init): Track;

Defined in: packages/cal3d/src/Animation.ts:53

Parameters

Parameter	Type
init	TrackInit

Returns

Track

Properties

boneId

boneId: number;

Defined in: packages/cal3d/src/Animation.ts:44

Index of the animated bone in the skeleton.

---

highRangeRequired

highRangeRequired: boolean;

Defined in: packages/cal3d/src/Animation.ts:51

Whether compressed translations need the ±2²³ range rather than ±128.

---

keyframes

readonly keyframes: Keyframe[];

Defined in: packages/cal3d/src/Animation.ts:45

---

translationIsDynamic

translationIsDynamic: boolean;

Defined in: packages/cal3d/src/Animation.ts:49

Whether the translation changes between keyframes (otherwise only the first one stores it).

---

translationRequired

translationRequired: boolean;

Defined in: packages/cal3d/src/Animation.ts:47

Whether keyframes carry translations (otherwise only the rotation is animated).

Methods

getBone()

getBone(skeleton): Bone | undefined;

Defined in: packages/cal3d/src/Animation.ts:61

Parameters

Parameter	Type
skeleton	Skeleton

Returns

Bone | undefined

---

sample()

sample(time): object;

Defined in: packages/cal3d/src/Animation.ts:69

The pose at time, interpolated between the surrounding keyframes (linear translation, spherical rotation) and clamped to the first/last keyframe.

Parameters

Parameter	Type
time	number

Returns

object

rotation

rotation: Quaternion;

translation

translation: Vector3 | null;
