ScreenCoordinateConstraint modifies the camera screen window to fit the target object(s).

Connection Type

Connection Name

Function

Input

input

The place in the node graph where you want to constrain the camera screen window to fit the target object.

 

Control (UI)

Default Value

Function

basePath

None

Sets the object to constrain. The basePath parameter options are available by clicking the dropdown menu.

For more information, refer to the Scene Graph Location Widget Type in Common Parameter Widgets.

targetPath

None

Sets the object(s) to which the object in basePath is constrained. The targetPath parameter options are available by clicking Add Locations or dropdown menu.

For more information, refer to the Scene Graph Location and Locations Widget Types in Common Parameter Widgets.

respectMotionBlur

Yes

When set to Yes, constraints are adjusted to allow for the target's motion within the time the shutter is open.

keepAspectRatio

Yes

When set to Yes, maintain the aspect ratio of the screen window.

When set to No, modify the aspect ratio of the screen window to fill as much of the frame as possible.

allowMissingTargets

No

When set to Yes, silently ignore the constraint if its target is not in the scene graph.

When set to No, produce an error on constraint resolution if the target is missing.

addToConstraintList

No

Adds base path to globals.constraintList at /root/world.

This is only needed for cases in which one constraint depends on another constraint already being evaluated. The globals.constraintList is used to specify the order of evaluation of constraints.

setRelativeTargets

No

Stores target paths in the scene graph constraint definition as paths relative to the base path.

Targets should still be specified as absolute paths in this node's parameters.
