Shadow/Object

Inspired by Larry Kagan (http://www.arts.rpi.edu/~kagan/). Normally, as artists create sculptures, they create shadows as a byproduct. The goal of this applet is instead to sculpt the shadow (draw it on a plane) and allow the object (sculpture) to manifest itself within the constraints of the shadow:
http://www.rpi.edu/~mcdonk/code/shadow/
If you are not convinced that your shadow is indeed being cast by the object, look at it from above.
To watch the many different manifestations of the cast object, hold down on 'c'.
The code isn't very clean, I got satisfied with it and switched to something else. There is a lot of room for expansion.
I saw Amit's Sonic Wire Sculptor yesterday, (after reinstalling Java so Jsyn would install, finally). Only after playing with it for maybe 15 minutes did I realize you could rotate the composition. This completely changed my interpretation. It made me curious, if you instead sculpted the shadow cast by a Sonic Sculpture, and allowed the sculpture to be cast from the shadow instead... You would end up with the same rhythmic patterns, but the pitch variations would be a product of the algorithm you used to determine sculpture height... I think it would sound really cool, especially to hear the different variations on the same rhythmic pattern...

nice concept. this sounds very interesting... but, no matter how much i rotate, press 'o', 'c' and 'r' i can only see a white box floating over a white plane ...
what am i doing wrong?

To draw, once you give the applet focus, hold down on the "shift" key while moving the mouse around the applet.

damn, sorry ... there i go again NOT reading everything, i skipped everything in the instructions down to what keys do what (lazy me) ... sorry for that.
(*blush*)
nice project

interesting idea - it kinda reminds me of some explorations into 4D shapes i've seen (though of course from an entirely different starting point). a quick transition between the different random forms might add a more sculptural element (maybe even having the shape in constant flux).

Thanks, that's a really cool idea... Shouldn't be too hard to write either. If I find something to procrastinate from doing (my calculus II final was the inspiration for this the first time), I'll have to add that!

This is really cool! A great concept (one of those "I wish I thought of that"-ideas). Maybe you could try to make the light-source more like how the sun casts shadows, instead of a point light-source. Maybe it would look more realistic, because I think it looks kind of odd in some way, when you look at it from above.

Koenie, I know what you mean about the fact that it looks a little odd. It doesn't perfectly match up because when you look at it from above you aren't in the exact same position as the light source. If you edit the code to change the position of the light a little, the match will be more apparent. Also, a point-source instead of an orthographic projection (like the sun) was used because it can be compared to "normal" lighting (like the sun). That is, in you can say "Here is the 'normal' shadow" (which you don't pay attention to), and then turn on the right point source light and say "here is the 'real' shadow".
