Do you remember what settings that you used for this ?
What numbers did you use ?
What size was your image that you uploaded ? ( How many pixels wide )

It seems very accurate !

Hello -

I used the side view picture from this post :

That web page quotes the Cd as 0.163. It has video mirrors. An electric motor drives the front wheels and a small diesel drives the rear (hence the cooling vents in the rear sides).

Hey, could you do one of my Jeep? I know it's probably going to be horrible, but I'd like to see where to start from.

I took the the image from the tirerack.com "wheels on car" visualizer. That's what I always do for late model cars.

Has anybody tried using this in the last 15 days. It currently says that there is a 162 minute queue, I have tried to be patient, but it doesn't do anything even after a couple hours. I would really like to see where my starting point is even though I know it's just a pretty little video that approximates the way the car punches a hole in the air. I think the fun may be over, the site isn't giving me anything.

The last few times I've tried it it has produced a file but it is only about 20kb (instead of the ~3MB it should be) and won't play.

Hello -

I just tried it with my squeeky-clean 256 wide*128 high, black and white bitmap and got nothing.

I sent the creator of Flow Illustrator a PM. This was a minor project for him, so I think he has moved on to other things (it's free so he has no obligation to support it). However, if he gets my note, he may be able to reset the server.

I noticed on the front page that it was being hosted by the school he used to teach at. I don't know whether EM could handle the extra bandwidth, but we're probably the ones that play most with it. I'm just thinking out loud, but would he be willing to have it hosted and help with the migration?
