star or planet.
Procedure
To create a basic animated r ingwave:
1.
On the menu bar choose Create > Extended
Primitives > Ringwa ve.
2. Drag in a viewport to set the outer radius of the
ringwave.
3. Release the mouse button, and then move the
mousebacktowardthecenteroftheringtoset
the inner radius.
4. Click to create the ringwave object.
5. Dragthetimeslidertoseethebasicanimation.
This is determined by the Inner Edge Breakup
group > Crawl Time settings.
6. To animate the ring’s growth, choose RingWave
Timing group > Grow And Stay or Cyclic
