Shader Family: Lens

Output: Color

This shader simulates depth of field by casting multiple eye rays into the scene so that an object at the focal distance is sharp and in focus, while objects at other distances are blurred.

Name

The name of the shader node displayed in the render tree. Enter any name you like, or leave the default.

plane

The focal distance at which objects appear in focus. More precisely, it is the negative Z coordinate of the focus plane in camera space. It must be a positive number.

radius

The radius of confusion at the camera's focal distance. Larger numbers increase the blurring effect. Note that large values can reduce the entire scene to a noisy cloud, so you may want to keep this value small.
