move an object by animation and leave it in the new position

[Guest]

How can a picture be moved by animation and left in its new position, ready
to be moved again

Martin,
If you have PPT2002/2003 you can apply a motion path to your picture. In the
custom animation task pane, click on Add effect, choose Motion path, there
are lots of possibilities.

 

[Guest]

What PowerPoint version are you using?
In PowerPoint 2002/XP and above, you can click Slide Show > Custom Animation.
Under the custom animation task pane, select Add Effect > Motion Path, then
select the choice of your preference. Holler back if you need more help.

Hi Shawn - re animation - let's take a simple example: a circle rolls on a
flat surface - I wish to trace the locus of a point on the circumference -
ie, a cycloid - how to?

Regards Mike

 

[Guest]

Do you mean tracing the outline of a circle?
Please send me a copy of a sample to pptheaven[at]gmail[dpt]com. Will be
able to help you better from there. Thanks.

Hi Shawn - re animation - let's take a simple example: a circle rolls on a
flat surface - I wish to trace the locus of a point on the
ircumference -
ie, a cycloid - how to?

If I understand what you're asking for, here's what I'd do.

1. Draw a circle. (I used one about 3" x 3") Give it no fill. This
represents the circumference.

2. Draw a tiny circle. (I used one about .2" x .2") Place it on the line of
the first circle. This represents the point on the circumference.

3. Select both circles and Draw|Group.

4. Custom Animation | Emphasis effect | Spin

If you don't want the actual circumference to show, then click twice in the
group to select the circumference circle and give it no line.

To make the circle roll, add a motion path to the group.

5. Select the group on the slide. Then in the Custom Animation Taskpane,
choose Add Effect | Motion Path. Choose a path. Maybe right, since you want
the circle to roll on a flat surface.

6. Set the motion path start property to "with previous."

If you want to use the Left motion path, then you'll probably want to change
your spin emphasis to counterclockwise. You can do that by selecting the
spin in the Custom Animation Taskpane, selecting the "Amount" property, and
either typing -360 in the Custom box or simply checking Counterclockwise
instead of Clockwise.

Hi Echo - thanx for your reply to my question on simple animation ...let's go back to the circle example - I followed your steps, and got the desired rolling motion of the circle

OK - but let's go a step further...I want to TRACE the path of the small
circle that is positioned on the circumference of the circle...for this case,
the resulting curve is a cycloid - for 360degr rotation of the base circle,
the cycloid will look like an arch - the arch will then repeat for each
additional 360 degr of rotation of the circle....

Looking fwd to hearing from you.....regards Mike

Hi, Mike.

I guess I'm still not following what it is you're after. Sorry.

If I needed the small circle to trace the path of the large circle, I would
make the large circle in my example have no line. That invisible line
combined with the spin will make the small circle move along a circular
path. Basically you're grouping the small circle with a larger object so as
to set the center point of the group to the fulcrum of the spin.

To actually trace that path, you might experiment with putting a background
colored box on top of part of the animation. I can create kind of a "trace"
of an arc effect that way. Still not sure that's what you're asking, though.

Hi Echo - let's clarify

http://mathworld.wolfram.com/Epicycloid.html

Pls go to this side, and look at the animated traces of the various curves -
that is what I want to learn how to do.....

Aha! Now *that* helps me see what you're after! (Picture, thousand words,
all that.) Thanks!

When I looked before for "cycloid," I saw
http://mathworld.wolfram.com/Cycloid.html, and
http://www-history.mcs.st-andrews.ac.uk/history/Curves/Cycloid.html

That second one is an example of what I meant (should have included the link
earlier, sorry) when I said you could hide part of the circle with a
background-colored rectangle. Since it would cover the bottom half of the
rotating (spinning) circle, only the tops would show, so you'd see an arc.

That said, the example you've shown is probably doable, but I think it would
be very tedious. Probably one of the people here better with animation than
I will be able to come up with specific steps, but I won't have time to play
with it until later.

Hello again -

Hello again -

http://mathworld.wolfram.com/Cycloid.html>
The above link shows exactly what I want to learn to do - that red or
orange
trace made by the point on the circle is the path I'd like to generate

Well, I played around a little with this this morning, and I think the red
trace is definitely the most difficult part. I wasn't able to get the timing
and placement exact, but here's what I did:

I created the circle that spins and moves and made it spin and move by
adding a spin emphasis and a motion path as described earlier in the thread.

I put a straight line at the bottom of the circles to serve as kind of a
"floor" or baseline.

For the red "arc" trace, I added an arc autoshape (under the basic shapes
list) and made it a semicircle by dragging one of the yellow diamonds. I
then resized until I got a semi-circular shape.

I put the arc underneath the floor, and I gave it a spin emphasis animation.
I specified a half spin in the animation's properties. I had the half-spin
begin "with previous" when the motion path and spin of the small circle
begins.

I placed a background-colored box on top of the arc. It basically covers the
bottom half of the slide. So the slide looks like the circle sitting on a
floor. Because the arc is covered by the box, you can't see it until it
animates.

Because the animation in the link actually goes twice, I extended the motion
path of the circle and set the spin emphasis to spin twice. And I created a
second arc immediately beside the first. (Actually, I just copied the first
arc). I set it to animate "with previous" also, but I showed the advanced
animation timeline and dragged its start point to begin when the first arc
ends.

The timing on mine isn't perfect, and I think my arc shape is a bit off.
This could probably be fixed with a lot of tweaking, but as I think I said
somewhere in the thread, I think it has the potential to be pretty tedious.

Maybe one of the others who's better at animation than I will have a better
method. I'm sure there's more than one way to skin this cat!

One thing -- it might be better to use the line tools and Edit Points to
draw the arc instead of using the autoshapes. Not sure, but you might get a
more accurately shaped arc.

Thanx for your efforts in working this problem - I sincerely apprciate it - but we're still not quite in synch!

The cycloid (or arch. loosely speaking) needs to be generated by the motion
of the small "dot" on the circumference of the circle.

Picture this: 1. circle on a flat surface, with the small dot on the
circumference. Now stick a pen thru the dot, so that as the circle begins to
move, the pen will describe a path. That's quite different from separately
drawing an "arch" as you had described.

So as the circle rotates, the "pen" will draw the path that the point on the
circumference travels. As we know, that resultant path is a cycloid - I just
haven't yet figured how to get that orange tracing.

I sincerely appreciate your efforts!

Regards Mike

Not quite sure why you think we're not in synch.

I understand that, but you're not going to get the "dot" to generate a trace
in PPT. So you have to fake it. I realize the arc I got from the autoshapes
isn't the exact form you need; that's why I mentioned you might have better
luck drawing your own "trace" line using the line tools and Edit Points.

If it helps, you can do as I did and copy the original circle to create the
kind of diagram that's in the link (with the point on the circle at
different positions) Remove the animations from the copies of the original
circle, of course. Use these as guides. Shyam Pillai's Capture Show add-in
might help your process http://skp.mvps.org/cshow.htm, as might Motion Path
Tools http://skp.mvps.org/mptools.htm.

I sincerely appreciate your efforts!

You're welcome, but my efforts to explain one way this could be accomplished
obviously aren't making sense. I can't put any more time into this, but I've
uploaded the file I was playing with. Remember, the timing and exact shape
of the arc/trace are not right, but this file should still serve as an
illustrative example. http://www.echosvoice.com/PPTFiles/cycloid.zip
