@acer Grrr. I have no idea why it stoppoed working with Maple 2015. For the next two days, I only have access to Maple 12.0.
The Maple 12 instructions given above work. HOWEVER,
- the gif produced is rather small (apparently 512x512 pixels). I found some documentation online about plotoptions to change width and height, but it doesn't work, i.e., plotsetup accepts the specifications for height and width, but the animation does not; the gif remains empty with no error message.
- Worse, the obeserver's perpective in the animation is not good. How do I specify that in the animate command?
- Animation does one forward pass. How do I make it at least do forward and back?
