These examples illustrate the basic features like moving objects by translation or rotation, and scaling their size.
Since the big gear has twice as many teeth, the little gear rotates twice as fast so they mesh correctly.
A simple example showing how changes in scale are interpolated between keyframes.
These 2D tiles are scaled in such a way that they continue to fit together with no gaps or overlap.
This demonstrates a good example involving translations and rotations.
Ikea Step Stool Assembly
This video shows a construction process where the parts move by both translation and rotation.
The camera also moves between keyframes.
This animation shows the assembly of a bedframe made entirely out of interlocking wooden parts.
The camera is also animated.
This video illustrates interpolation by translation, rotation, scale,
scale + translation, and scale + rotation.
The fish swim in circles (via rotations) inside three aquariums in a seafood restaurant.
Section cuts reveal how 24 pencils, with hexagonal cross-sections,
criss-cross from four directions, and interlock with each other.
Animating Nested Objects
A nested object moves relative to its parent.
If the parent object moves too, the combined motion can be more complex than a simple translation or rotation.
The door on the far right is a top-level object, and the middle door is a subgroup.
While the right door rotates 90 degrees clockwise, the middle door rotates 90 degrees counter-clockwise relative to it.
The combination of these two rotations produces the desired motion of folding doors.
The rocker arm is a top-level object, and the bridge is a subgroup.
While the arm rotates about the pivot point,
the bridge rotates through an equal angle in the opposite direction relative to it.
The combination of rotations raises and lowers the bridge while keeping it level.
Each little gear rotates about its center.
At the same time, a second rotation revolves the three little gears as a group about the center of the big gear.
These are the best of the best.
This video reveals the beautiful symmetry when Platonic Solids, all the same size, intersect.

The ultimate example for animated subcomponents.
The palm is the top-level object.
Each joint is a subcomponent of the joint it is attached to higher up.
Moving any joint moves everything lower down.
The animations include translations, rotations, and moving subcomponents.
The images were exported from SketchUp and composed in Sony Movie Studio, which added the audio, sound effects, and titles.
Tokyo architectural studio
We used the wooden elements of the shrine,
and the spirit of dismantling and assembly as a field of action for analyzing domestic Japanese environments through an animated drawing.
Viking Lander Leg Animation
This video shows a digital 3D model of the Viking '75 Mars Lander's core body and landing legs,
illustrating the operation of leg mechanisms.
