Range
The Range control can be used to limit the effect of a deformation to a small portion of the geometry.
The Range control is not available when the Bender Type is set to Shear.
Group Objects
If the input of the Bender 3D node contains multiple 3D objects, either through a Merge 3D or strung
together, the Group Objects checkbox treats all the objects in the input scene as a single object, and
the common center is used to deform the objects, instead of deforming each component object
individually.
Common Controls
Settings
The Settings tab in the Inspector is common to all 3D nodes. This common tab is described in detail at
the end of this chapter in “The Common Controls” section.
Camera 3D [3CM]
The Camera 3D node
Camera 3D Node Introduction
The Camera 3D node generates a virtual camera for viewing the 3D environment. It closely emulates
the settings used in real cameras to make matching live-action or 3D-rendered elements as seamless
as possible. Adding any cameras to a 3D composite allows you to frame the elements in a composite
how you want and animate the camera during a scene to create moving camera shots.
Camera Projection
The Camera 3D node can also be used to perform Camera Projection by projecting a 2D image
through the camera into 3D space. Projecting a 2D image can be done as a simple Image Plane
aligned with the camera, or as an actual projection, similar to the behavior of the Projector 3D node,
with the added advantage of being aligned precisely with the camera. The Image Plane, Projection,
and Materials tabs do not appear until you connect a 2D image to the magenta image input on the
Camera 3D node in the Node Editor.
Stereoscopic
The Camera node has built-in stereoscopic features. They offer control over eye separation and
convergence distance. The camera for the right eye can be replaced using a separate camera node
connected to the green left/right stereo camera input. Additionally, the plane of focus control for depth
of field rendering is also available here.
If you add a camera by dragging the camera icon from the toolbar onto the 3D view, it automatically
connects to the Merge 3D you are viewing. Also, the current viewer is set to look through the
new camera.
Alternatively, it is possible to copy the current viewer to a camera (or spotlight or any other object) by
selecting the Copy PoV To option in the viewer’s contextual menu, under the Camera submenu.
