Homework 7

a. Multiple Color Tracking

Source

//do the second color
	if (oneColorIsSet) {
		if (x >= 0 && x < 320 && y >= 0 && y < 240){
			int pixel = y * 320 + x;
			hue2 = videoGrayscaleHueImage2.getPixels()[pixel];
			sat2 = videoGrayscaleSatImage2.getPixels()[pixel];
			val2 = videoGrayscaleBriImage2.getPixels()[pixel];
		}
	}

This code tracks 2 colors.

b. Face tracker

Source

void testApp::eyes(float x, float y, float w, float h) {
	ofSetColor(0, 0, 0);
	float newx = ofMap(x, 0, 320, 65, 200);
	float newy = ofMap(y, 0, 240, 84, 112);
	ofEllipse(newx - 40, (newy+h)-10, w/7, h/2);
	ofEllipse(newx + 270, (newy+h)-10, w/7, h/2);
}

The not-so-friendly cat's eyes follow the face detected. The code isn't setup to handle faces detected beyond the range demonstrated and might glitch out.

b. 5 examples of unique alternative drawing interfaces

Bomomo

Bomomo is a drawing interface created in javascript by Philipp Lenssen. The tools/brushes are very unique and interesting.

Scribblebots

ScribbleBots are drawing bots created by Jon Cumberpatch. The allow users to create drawing and share them over the internet. Other users can reproduce these drawings by downloading them to the ScribbleBot.

Line Rider

Line Rider is a drawing game in which the user can draw lines for the rider to ride.

Qbesq

Qbesq is a flash drawing interface which can be used to draw some interesting fractals.

Kinectic Sketch
