Documentation / scene / ZHairStrandSetJSON

Type Alias: ZHairStrandSetJSON

ZHairStrandSetJSON = object

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:56

One strand set as described by the manifest.

Remarks

Mirrors StrandCurveSet, with the per-point colour and transparency channels a .hair file may carry. Control points are contiguous: strand i owns the pointCounts[i] points following the running sum of the counts before it.

Properties

name

name: string

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:58

Name carried over from the source object.

---

strandCount

strandCount: number

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:60

Number of strands.

---

pointCount

pointCount: number

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:62

Total control points across all strands.

---

bounds

bounds: [number, number, number, number, number, number]

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:71

Axis-aligned bounds of the control points, as [minX, minY, minZ, maxX, maxY, maxZ].

Remarks

In the file's own units, before unitScale is applied, so that a reader can size a node without touching the payload.

---

positions

positions: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:73

Control point positions, 3 float32 per point.

---

pointCounts

pointCounts: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:75

Control point count per strand, 1 uint32 each.

---

widths?

optional widths?: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:77

Strand width as a diameter, in the same unit as positions.

---

widthPerStrand?

optional widthPerStrand?: boolean

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:79

True when widths holds one value per strand rather than per point.

---

uv?

optional uv?: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:81

Root UV, 2 float32 each.

---

uvPerPoint?

optional uvPerPoint?: boolean

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:83

True when uv holds one pair per point rather than per strand.

---

colors?

optional colors?: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:85

Per-point colour, 3 float32 each. Only .hair sources carry this.

---

transparency?

optional transparency?: ZHairBufferRef

Defined in: libs/scene/src/asset/loaders/zhair/zhair_format.ts:87

Per-point transparency, 1 float32 each. Only .hair sources carry this.
