Volume Projected

The Volume Projected object is used to create light beams from directional light sources, such as car headlights, searchlights or beacon light. It can also be animated to simulate a flow of particles that moves from the light source or even swirls. Only a volume proj material can be assigned to it.Volume Projected对象用于创建来自定向光源的光束,如汽车大灯、探照灯或信标灯。它也可以动画来模拟从光源移动的粒子流,甚至是漩涡。只能将一个volume proj材料分配给它。

Options

Parameters参数

In the Volume Projected section (Parameters window -> Node tab), you can adjust the following parameters of the Volume Projected object:Volume Projected 部分(Parameters 窗口 - Node 选项卡),您可以调整 Volume Projected 对象的以下参数:

Size Size of the smallest Billboard in units. By the minimum value of 0, Volume Projected is not rendered at all.规模最小的Billboard单位。的最小值 0 Volume Projected不呈现。
Radius Length of the light beam along the Z axis, in units.光束沿Z轴的长度,在单位。
FOV

Width of the light beam. It is specified as the angle of the beam cone (in degrees).光束的宽度。它被指定为梁锥的角度(度)。

  • By the minimum value of 10, the beam is the narrowest.的最小值 10 强,最窄的光束。
  • By the maximum value of 90, the beam is the widest.最大值的 90 强,梁是最广泛的。
Step

Distance between neighboring Billboards.Billboards邻国之间的距离。

  • The lower the step is, the smoother the beam, since more Billboards are rendered.一步是越低,梁越平滑,因为更多的Billboards呈现。
  • The higher the step, the more discrete the beam, but the higher the performance is.一步,越高越离散梁,但性能越高。
Velocity Velocity with which Billboards move to the end of the beam (along the Z axis).速度与Billboards搬到结束的梁(沿Z轴)。
Rotation

Angle of Billboards rotation (in degrees). This angle is set for the Billboard at the end of the beam.Billboards旋转角(度)。这个角是设置为1月底_phl光束。

  • If positive, all Billboards rotate clockwise.如果阳性,所有Billboards顺时针旋转。
  • If negative, all Billboards rotate counterclockwise.如果消极,所有Billboards逆时针旋转。
