Re: Draw polygons on moving cars in video

Sounds like the kind of thing Macromedia Flash is good for. While
there may be a SMIL-like way to script it in code, as long as you're
not trying to build a generalized tool for following objects with a
hotspot, Flash ought to be just about right.

I am trying to find a way to display a video of a car moving down
the street and draw a polygon around the car as it moves. I
would like to use HTML+TIME, but am open to any solutions. I have
the location of where the polygon should be drawn in the video, but
I cannot figure out how to do this. I believe I need to show the
first frame of the video and draw the polygon around the car for
this frame in one sequence. Then I need to show the next frame of
the video and draw the polygon around the car on this frame as the
next sequence. Since the car is moving the polygon will not be in
the same location in each frame. Can anyone suggest a way to this?
