Make a drawing analyzer that tells what mood the person who drew a stroke is in. happy ? sad ? thoughtful ? confused ? tentative ?
certain things might be useful – elapsed time, average length, etc. think about what you can know from a drawing. Please ask questions if you need assistance on anything.
Six months ago I received the most painful phone call at 2 am in the morning. It was my brother at the phone, who had the sad task to tell me that our father had passed away. Part of me is still thinking that the phonecall and the flight back home was a bad dream…
based on the gesture resampling code, make something interesting. for example, can you make one drawing turn into another? Can you mix two strokes together to make a third? can you make a stroke turn into a straight line? In the example I posted , the stroke becomes a circle, but it doesn’t matter at all what you’ve drawn, or how you’ve drawn it. Can you get information about what was drawn, the length, the angle, etc, and use it to control how it is transformed?
given that you can make each stroke a fixed number of points, think about how that can be used in some meaninful, playful way.
I created a drawing tool that resamples the gesture of the user depending on the size of the stroke that has been drawn. There are three basic figures in the gesture can be animated to; a circle, a six points star and a 20 points star. The circle corresponds to the shortest stroke, the 6 point star to the medium stroke, and the 20 point star to the longest stroke.
a) (working on paper) make one reasonably complex drawing with one line (one connected line only). this could be a one line signature, or a cursive word, or something else. Then, working on pieces of tracing paper over the drawn line, try to “approximate the line” with a certain number of points, for example, if you were to draw the line using only 10 connected points, what would it look like? I would like you to try “resampling” the line with 20, 15, 10, 5, and 2 points. think about what information is preserved and lost between the resamples.
b) (working in code) make a drawing tool where you use the distance formula to sum up the length of the line being drawn. Do this for one stroke only (so earlier code could be useful, or you can limit the gesture to one stroke, etc). In addition to calculating the total length of a stroke, can you also identify the shortest and longest section (ie, pt 6 -> pt 7) ? for the mega nerds, can you calculate the mean value (average value) and the std deviation of these section lengths?
c) using the stroke / angle / body code we did in class, can you create an interesting drawing tool? think about how the size of the body of a stroke could be varied. for example, in the second code example now, fast motion = larger stroke, could you reverse so that slow motion leads to a larger stroke? Could you draw it in a more interesting way? think about incorporating media, such as images, into how you draw. make an elegant stroke machine.
