Particle System ‣ Velocity

The initial velocity of particles can be set through different parameters, based on the type of the particle system. If the particle system type is Emitter or Hair, then the following parameters give the particle an initial velocity.

Normal (Pháp Tuyến/Bình Thường)

The emitter's surface normals (i.e. let the surface normal give the particle a starting speed).

Tangent (Tang/Tiếp Tuyến)

Let the tangent speed give the particle a starting speed.

Pha Tiếp Tuyến (Tangent Phase)

Rotates the surface tangent.

Căn Chỉnh đối tượng (Object Align)

Give an initial velocity in the X, Y, and Z axes.

X, Y, Z

Vận Tốc của Đối Tượng (Object Velocity)

The emitter objects movement (i.e. let the object give the particle a starting speed).

Ngẫu Nhiên Hóa (Randomize)

Gives the starting speed a random variation. You can use a texture to only change the value, see Controlling Emission, Interaction and Time.
