Im now thinking about using an AR marker, which is projected on the wall, so I can figure out the rotations using a 3D library. After which I can recreate an MC with those rotations, and then its just getting a point in 3D space and converting it to 2D using that MC. Will give that a shot, see what happens.

I did this experiment a while ago, called LaserPong ( http://vimeo.com/27145395 ). Basically, its a laser-pointer detection script, linked to a Pong game.

There are 2 scripts in it that could be improved and I am looking for some advice.

First part is perspective correction. I have set up a cam that monitors the projected image, to capture the laser. But if the cam is set to an angle (pretty much always), I need a way to tell the x and y values of that point, with perspective calculated out of it. Its basically the difference in getting x and y value of a point on a 2D plane, versus on a 3D plane (rotated). I did find a script that could turn bitmap points in perspective to a rectangle, but its quite slow. So Im looking for a faster script.

Second, blob detection. The laser point is a blob, and there are multiple points, so multiple blobs. I need a faster blob detection method than Im currently using. The one I use now goes through all pixels (black and white image of webcam), finds a white spot (blob), turns it red, get bounds of red in image -> new blob. Then turns it black so it disappears, and repeats until all blobs are gone. This take a lot of time and is pretty heavy. So again, I need a faster script.

If anyone has any advice / script / whatever, share!

You crazy asians and your reversed date notation :chuckle:

Well, it actually makes sense. Compare it to this: when you say 123, you say 100, 20 and so from largest to smallest number. With the date, its the same thing: year (largest amount of time), month (middle) and day (smallest).

Our notation isnt that bad, just reversed. I dont get the US notation though, what sense does that make? :P

Its a pain in the ass if you ask me. Took a few hours of my life just to find out I couldnt export to FP11 like I test my movies now. Not going through that again, let them come up with a way to install it without a hassle.

Edit: What?! I have a black paw! :O When did that happen?..

Dont forget about accessibility, it has to be viewable by anyone, anywhere, on any machine using any browser. Fixing everything for everything can take some time. So 16 months isnt that shocking for a gov site.

Btw, those that have been to Gmunks talk at FOTB , remember that he said he worked with 6 people for 1.5 years just to create 8 minutes of special effects film in TRON . Good things take time to make.

Although I dont really understand why it had taken them 16 months to create this site..

^ That theme couldnt have cost $35.. And I can find cheaper hosting than that as well :P

But yea, gov sites tend to be very expensive while not being that special at all

Yea I know, have been pretty busy lately. Matt has been nothing but helpful, so Im cool with him ;)

All I can say about the things happening on the web right now is ‘we will see where it goes’.
