Xoay Chiều (Rotation)¶
Tham Chiếu (Reference)
- Panel (Bảng):
These parameters specify how the individual particles are rotated at the start of, and during, their lifetime. You can visualize their orientation by setting Display As to Axis in the Hiển Thị Cổng Nhìn (Viewport Display) panel.
- Trục Định Hướng (Orientation Axis)
Aligns the X axis of new particles to:
- Không (None)
Trục Toàn Cầu.
- Normal (Pháp Tuyến/Bình Thường)
The emitter's surface normal.
- Pháp Tiếp Tuyến (Normal-Tangent)
The emitter's surface normal, additionally aligning the particle's Y axis to the positive V direction in the emitter's active UV map. This makes it possible to deform the emitter while keeping particle rotation consistent.
- Velocity / Hair
The particle's initial velocity vector/hair growth direction.
- X, Y, Z Toàn Cầu (Global X, Y, Z)
One of the global axes.
- X, Y, Z của Đối Tượng (Object X, Y, Z)
One of the emitter's local axes.
- Ngẫu Nhiên Hóa (Randomize)
How much to randomize the particle's initial rotation (along all axes).
- Pha [Sóng] (Phase)
Initial rotation around the particle's X axis, going from -1 (-180°) to 1 (180°).
- Ngẫu Nhiên Hóa Pha (Randomize Phase)
Maximum random rotation to add to the Phase, going from 0 (0°) to 2 (360°).
- Năng Động (Dynamic)
Whether the particles' rotation can change over time.
Vận Tốc Góc (Angular Velocity)¶
Tham Chiếu (Reference)
- Panel (Bảng):
Lets you configure if and how particles should spin over time. Dynamic needs to be enabled for this to work.
- Axis (Trục)
The axis to spin around. If this is set to Velocity, Horizontal, or Vertical, particles will additionally spin to keep the same orientation relative to their direction of movement, even if Amount is zero.
- Không (None)
Spinning is disabled.
- Tốc Lực (Velocity)
Spin around the particle's velocity vector.
- Chiều Ngang (Horizontal)
Spin around the axis that's horizontal (lying in the global XY plane) and perpendicular to the particle's velocity. Particles moving along the global Z axis won't spin because no unique rotation axis exists in this case.
- Chiều Dọc (Vertical)
Spin around the axis that's perpendicular to both the particle's velocity and the above Horizontal axis. Particles moving along the global Z axis won't spin.
- X, Y, Z Toàn Cầu (Global X, Y, Z)
Spin around the chosen global axis.
- Ngẫu Nhiên (Random)
Spin around a random axis.
Gợi ý
If you use a Hướng Dẫn theo Đường Cong (Curve Guide) and want the particles to always point in the direction of the curve, you should set the Orientation Axis to Velocity / Hair, enable Dynamic, and set the Angular Velocity Axis to Velocity.
(For a regular object, you'd normally use the Follow Curve option of a Ràng Buộc Đi theo Đường Dẫn (Follow Path Constraint) or the legacy Follow option of the curve itself, but these don't work for particles.)
- Số Lượng (Amount)
How fast to spin around the Axis.
