The Bongo object properties panel manages the animation data for each animated object.
Allows the object to be animated. Adds the object to the Animation Manager.
See also: Animation Overview.
Removes the object from the Animation Manager.
Removes all keyframes from the object. The pivot and IK data are not removed.
Matches the animation properties of one object to another.
Moves the object's pivot.
Rotates the object's pivot.
Specifies a parent object for the selected object. See Hierarchical Animation.
Opens the Advanced Hierarchy Settings dialog box for the object.
When the object is constrained, the pivot displays a dotted constraints heading indicator. The constraint heading determines the direction the object will use to face an object to which it is constrained.
By default, the constraints heading is along the object pivot's x-axis.
A dotted arrow shows the direction of the constraint heading direction.
At the Pick new heading vector prompt, pick a new direction on the screen, press Enter to use the current direction heading, or choose a command-line option.
Clearing the checkbox temporarily turns the object animation off.
Toggles the pivot display for the selected objects.
Animated objects display a pivot icon in the Rhino viewports. By default, the pivot is created at the center of the object’s bounding box. Bongo rotation is applied around the x, y, and z-axes of the object pivot. Bongo scaling is applied along the x, y, and z-axes of the object pivot.
Displays a curve showing the path of the object’s pivot over the entire course of the animation.
Displays points or dots at keyframes and specified intervals along the path of the object’s pivot. Set the style and interval on the Bongo Document Properties page.
Pivot path display.
The display can either be point objects or dots. The dots display the tick number.
Repeats the animation action between looping markers.
Looping markers appear for selected looping objects. This shows which tick is determining the properties of the object given the current looping values for that object.
Sets object rotation around world x, y, and z instead of rotating around its own pivot.
Rotation and scale are tweened componentwise as three separate numbers. Position can be tweened either componentwise or with 3-D tweening.
When 3-D tweening is not checked, componentwise tweening is used. This means that each component x, y, and z are tweened as numbers - each forming its own curve.
Sets the order of rotation when rotation in 3-D occurs simultaneously in all axes. By default, objects apply the rotation transformations in the order X, Y, and then Z.
Objects can be constrained to path curves or objects.
A constraint can be animated on or off or with varying weight over time. Keyframes also store the position of the object along a path constraint. This is called the constraint parameter and varies from 0.0 at the start of the path to 1.0 at the end.
Common uses for constraints include:
All animated objects start with simple pivots and no constraints. Selecting the Simple Pivot option effectively disables any constraints that may have been applied to the object.
Simple constraints force objects to attach themselves to other objects.
Original object location.
The object will move along the path curve tangent to the curve, while keeping the object's z-axis pointed up (the world z-direction) as much as possible.
The object will move along the path curve while keeping the object's constraint heading parallel to the curve tangent.
The object's constraint heading to face another object's pivot.
Multiple constraints can be used. In the clip below, the object is constrained to path and to look at the center of the circle.
The To Path constraint forces the object along a curve without changing its orientation.
The object's pivot moves to the pivot of a target object. In the clip below, the point is constrained to move along the circle, then the box's is constrained to the point's pivot. The box will then start to move along the circle following the point's pivot.
Add a constraint.
Remove a selected constraint.
The Monitor section displays information about the object. The space, location, rotation, and scale of the object pivot are displayed and updated as the timeline slider is moved or the animation preview is played. The values shown in the monitor are especially useful when using expressions.
