User Manual

Type
This control is used to determine the type of falloff applied to the fog.
 Linear: Defines a linear falloff for the fog.
 Exp: Creates an exponential nonlinear falloff.
 Exp2: Creates a stronger exponential falloff.
Near/Far Fog Distance
This control expresses the range of the fog in the scene as units of distance from the camera.
The Near Distance determines where the fog starts, while the Far Distance sets the point where
the fog has its maximum effect. Fog is cumulative, so the farther an object is from the camera,
the thicker the fog should appear.
Common Controls
Settings Tab
The Settings tab controls are common to many 3D nodes, and their descriptions can be found
in “The Common Controls” section at the end of this chapter.
Image Plane 3D [3IM]
The ImagePlane3D node
Image Plane 3D Node Introduction
The Image Plane node produces 2D planar geometry in 3D space. The node is most commonly
used to represent 2D images on “cards” in the 3D space. The aspect of the image plane is
determined by the aspect of the image connected to the material input. If you do not want the
aspect ratio of the image to modify the “card” geometry, then use a Shape 3D node instead.
Inputs
Of the two inputs on this node, the material input is the primary connection you use to add an
image to the planar geometry created in this node.
–
SceneInput: This orange input expects a 3D scene. As this node creates flat, planar
geometry, this input is not required.
