Created with Emmanuele Mazza

An example of how to create movement along bezier curves. Ii includes algorithms for finding a point along a bezier curve with varying numbers of control points.The simulation creates a curve is 3 dimensions and uses a time blend to animate the circle along the curve.

This is a very simple addition to the openFrameworks example, but quite useful. Recently, a colleague needed to play a large movie that spanned two screens, but we could not get any players to run it (at least on that computer), so I wrote a quick player to do it.

fullScreenMoviePlayer

I had some errors in the previous code (namely the getPixel and draw)

Here is an updated version:

floatImage

You can now set an ofCVGrayscaleImage from the float Image:

myFloatImage.setGrayscaleImage(myGrayImage);

This is basically how I faked a multi-touch screen using just my video camera. It is not the most efficient or robust way to make a multi-touch interface, but it made sense for the installation. The code can be used for other purposes as well. In particular, converting from a contour or polygon vertices into an image has come in handy quite a few times.

Built with openFrameworks.

A simple app that demonstrates how to use a float image to slowly blend two images together. This can be a useful way to learn a background when performing computer vision.

The original background capture very slowly adds in the current frame so
objects that are introduced into the scene will be integrated into the
background model over time.

Note: the application uses some additions to the openFrameworks computer vision add-on.
