Controls Tab
Most of the Controls tab is taken up by common controls. The Image Plane specific controls at
the top of the Inspector allow minor adjustments.
Lock Width/Height
When checked, the subdivision of the plane is applied evenly in X and Y. When unchecked,
there are two sliders for individual control of the subdivisions in X and Y. This defaults to on.
Subdivision Level
Use the Subdivision Level slider to set the number of subdivisions used when creating the
image plane. If the Open GL viewer and renderer are set to Vertex lighting, the more
subdivisions in the mesh, the more vertices are available to represent the lighting. So, high
subdivisions can be useful when working interactively with lights.
Wireframe
Enabling this checkbox causes the mesh to render only the wireframe for the object when using
the OpenGL renderer.
Common Controls
Controls, Materials, Transform, and Settings Tabs
The remaining controls for Visibility, Lighting, Matte, Blend Mode, Normals/Tangents, and
Object ID are common to many 3D nodes. The same is true of the Materials, Transform, and
Settings tabs. Their descriptions can be found in “The Common Controls” section at the end of
this chapter.
Locator 3D [3LO]
The Locator3D node
Locator 3D Node Introduction
The Locator 3D node’s purpose is to transform a point in 3D space to 2D coordinates that other
nodes can use as part of expressions or modifiers.
When the Locator is provided with a camera and the dimensions of the output image, it
transforms the coordinates of a 3D control into 2D screen space. The 2D position is exposed as
a numeric output that can be connected to/from other nodes. For example, to connect the
center of an ellipse to the 2D position of the Locator, right-click on the Mask center control and
select Connect To > Locator 3D > Position.
Inputs
Two inputs accept 3D scenes as sources. The orange scene input is required, while the green
Target input is optional.
SceneInput: The required orange scene input accepts the output of a 3D scene.
This scene should contain the object or point in 3D space that you want to covert to
2D coordinates.
