Light Omni
Light Omni is a point source emitting light in all directions (360 degrees) and realistically reproducing shadow cast. This type of light serves to simulate light sources with bright center and equal roll-off of intensity. An example of such a light is an ordinary household lightbulb, uncovered and hanging from the ceiling. Light Omni proves useful for general lighting purposes in indoor scenes because of its nondirectional qualities.Light Omni是一个点光源,它在所有方向(360 度)发光,并真实地再现阴影投射。这种类型的光用于模拟中心明亮且强度均匀下降的光源。这种灯的一个例子是普通的家用灯泡,它是无遮盖的并且悬挂在天花板上。 Light Omni由于具有非定向性,因此被证明可用于室内场景中的常规照明。
Please note that as Light Omni uses cubemap modulation, the shadowing by this source requires 6 passes and can be expensive.请注意,由于Light Omni使用立方体贴图调制,因此此源进行的阴影需要6次通过,并且可能会很昂贵。
Light Omni has a variety of shapes and, therefore, can be used to create area lights, for example, realistic interior or street lights.Light Omni有多种形状因此,可用于创建区域照明,例如,现实的室内照明或路灯。
