Volume Omni

Volume Omni is used to create a visible volume of light emitted from a flat surface, for example, embedded wall lights, flat ceiling lights or fluorescent lamps. Only a volume_omni material can be assigned to it.Volume Omni用于创建一个可见的光发出一个平坦的表面,例如,嵌入墙灯,平坦的顶灯或荧光灯。只有volume_omni材料可以分配给它。

Volume Omni objects体积Omni对象

Volume Omni is rendered in the following way: in the center there is a flat rectangle. It simulates a surface that emits light. Around its edges, there are billboards that always face the camera. They create a light volume around the surface even when you look on the omni from the side, and make the volume fade out smoothly. When you look at the object at 90 degrees, it is not visible at all.Volume Omni呈现在以下方式:在中心有一个平坦的矩形。它模拟了一个发光的表面。在边缘周围,有广告牌总是面对镜头。他们创建一个光卷表面甚至当你从侧面看泛光灯,并使体积淡出顺利。当你观察对象在90度,它是不可见的。

Volume Omni Parameters体积Omni参数#

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

Edit Size

Toggles the editing mode for the Volume Omni node. When enabled, the Volume Omni sides that can be resized are highlighted with the colored rectangles. To change the size of a side, drag the corresponding rectangle.切换编辑模式Volume Omni节点。启用时,Volume Omni双方可以调整大小的突出显示颜色的矩形。改变大小的一边,拖动对应的矩形。

Width Width of the central rectangle in units (along the X axis).中央矩形单元的宽度(沿着X轴)。
Height Height of the central rectangle in units (along the Y axis).高度中央矩形单元(沿着Y轴)。
Radius Size of Billboards around the edges in units.0边缘_phl单元的大小。
Attenuation

Specifies how fast object fades out when viewed from the side.指定对象的速度消退时从侧面观察。

  • By the minimum value of 0, Volume Omni doesn't fade out. It abruptly disappears when you look at Volume Omni at 90 degrees.的最小值 0 Volume Omni不会淡出。它突然消失当你看Volume Omni在90度。
  • The higher the value is, the more faded out Volume Omni is at a small viewing angle. High values also decrease overall intensity.值越高,越淡出Volume Omni小视角。整体强度高值也减小。
