    Virtual Transparencies in Powerpoint (Windows 98)

    Everyone remembers the low-tech world of transparencies. One could have a basic picture (say a floor plan of a house) then overlay other transparencies with other bits of information on them.

    Can this be done in Powerpoint? I don't mean adding drawing objects because I want to have more than one "layer".

    Would you be removing these "transparencies" in random fashion, or simply leaving them there?

    If you're leaving them, adding drawing objects would be the easiest way to go (to me). You can have all required elements for each "transparency" animate immediately together.

    Does this make sense?

    I would be leaving them there until I had finished the "series" then removed all the "overlays" and started with another set.

    What I'd like to do is a presentation of groundwater and soil contamination at a particular location. I have all the hard copies of the figures that I can have someone in the office convert to an electronic format. The sampling has been done over time and I'd like to show each sampling event (soil locations and results of soil sampling), then do groundwater sampling locations over time and the data from each sampling event.

    I think I understand what you mean by doing the animation and that might be the way to go. Drawing would take such a long time but that may be the only way I can do it in Powerpoint.

    Thanks for your help!

    Don't forget what PPoint is for. Transmission of ideas. I've seen too many speakers get all wrapped up in the technical aspect of a slide when the point is for the slide to support or clarify what YOU are saying. If the slide says it all, why do I need you?

    I had a doctor I worked with who was trying to show arm movement in a certain diagnosis. When he called me he was all wrapped up in how to reproduce the muscle groups and their interaction. I took his slide and put three rectangles (with round corners) on the screen (Arm shapes). I was able to show the lower arm and hand (Objects two and three) moving with animation. He ended up liking the simpler, clearer approach.

    I think this type of presentation may be more suited to a GIS type of program. I don't know GIS (but am about to stumble through) and I know enough PP to be dangerous. I have PP at home and at work so I could work on this presentation 24/7 if I had to, but this just might not be possible.

    Thanks for your suggestions!

    Hi,

    I think doing what you want is not that hard. There are 2 approaches but I'd go with the first one:

    As I understand it, you have a base "transparency" - let's call this object 1. On top of that, you want to put object 2 then 3. Now you're finished with 1+2+3. You now want to start with 1 again and add 4, then 5, then 6.

    First let me say that if you want sevreal objects to appear together, it's probably best to group them (see the Draw button on the Drawing menu). In fact, I don't think you could do otherwise. So the object 1, 2,... above is a grouped set of items.

    The ability to see thru the "transparencies", just like the old kind, somewhat depends on what each contains. If they're line drawings, the effect is pretty much additive. When I place #2 on top of #1, I can still see what's underneath 2. If they are solid shapes, what's on #2 will subtract from what you can see under it on #1. While with transparencies, this is not totally true, having a solid shape on #2 would still detract from what's under it.

    With that said, onto the solutions:

    approach 1:
    - bring in your objects 1 with animation or not (it can be there to begin with - not animated)
    - bring in 2 then 3.
    -new slide: start with 1 (during creation, just copy 1 thru the clipboard onto a new slide), then bring in 4, 5, 6
    No reason everything has to be on 1 slide. When I used transparencies, if I wanted to give out a paper copy for people to have, I put 1+2+3 on the copy machine, make my copy. Then I'd put 1+4+5+6 on the copy machine, make my copy.

    approach 2:
    - bring in 1 (as above), then 2, then 3.
    - bring in a white box that covers the entire slide (or enough to cover 1+2+3 and whatever color you want)
    - bring in another copy of 1, then 4, then 5, then 6
    This is messy from a creation point of view. I like approach 1 better - easier to manage during the creation process if you have to edit things.

    HTH
