Looking to upgrade (3D)

I upgraded my projector a while back and it can do 3D. I was never interested in 3D, I just got a good deal and bought it and 3D was a bonus. But recently thought my girls would love this outdoors. They are 4 and 6.

I have 100 inch sheet that I used to hang on my swing set. The swing set went away so I either need to build a frame for it or get something else. If I buy something else, I'd like to step up to 150 inch or so screen. Budget...not sure, but I'd be willing spend a few hundred dollars or so if it is worth it.

Question 1: Will the slight movements impact 3D?
Question 2: For 3D, thoughts on the sheets, inflatables, or something else?

Thanks in advance

Not sure what you mean with regards to "slight movements".

Take a look at Carl's Place for a screen/screen kit. Very good product at a reasonable price.
Standing Projection Screen Kit (carlofet.com)

Because of the way 3D works with active glasses, you want a bright image.

Additionally, moving from a 100" screen to a 150" screen is a big size increase, almost a 45% increase in size. So you want to make sure that your projector is capable.

Keep in mind active 3D glasses will take away maybe 70% or 80% of your projector's brightness. So you might want a high gain screen unless your projector already has a lot of brightness headroom. But also keep in mind too high gain will create other problems. The throw distance of projector to screen impacts how much hotspotting it will create. Less is always better but depending on the throw distance, for 3D, you should usually be OK up to 2, 2.2, maybe 2.5. But it depends.

You may not need 100% as much brightness in 3D as with 2D, since no set up is perfect and there are always tradeoffs you have to make, but make sure you have "enough" that you're satisfied.

I've never seen one of the inflatable screens in action. I am assuming the air flowing thru them might make the wobble some? Maybe not, just seems like it would to me. If so, I could image imagine that impacting the 3D? But again maybe not. I've done a lot of indoor home theater stuff. But never 3D and not much outside.

My projector should handle it. I forget the model number, it is an Optoma 4 something...Around 4000 lumens and supposedly a 300 inch screen.

Did not know this, but I should be okay on brightness. I'm around 4000 lumens.
