In drei Teams wird der Bau des Radars vorbereitet:
Einfache grafische Elemente mit Processing darstellen, ein Beispiel:
int tickRadius; //radius of the ticks int handPos; //position of the hand in degree //window origin in the upper left corner int x_M; //window center in x-direction int y_M; //window center in y-direction void setup() { //window size in pixel size(700,500); tickRadius = 200; handPos = 0; x_M = width/2; y_M = height/2; } void draw() { drawBackground(); drawCenter(); drawTicks(); handPos = drawHand(handPos); } void drawBackground() { // Using only one value with color() // generates a grayscale value. color c = color(65); // Define 'c' with grayscale value background(c); // 'c' as background color } void drawCenter() { color c = color(255, 204, 0); // Define RGB color 'c' fill(c); // Use color variable 'c' as fill color noStroke(); // Don't draw a stroke around shapes ellipse(x_M, y_M, 40, 40); // Draw left circle } void drawTicks() { color c = color(255, 204, 0); // Define RGB color 'c' stroke(c); for(int i = 0; i < 360; i+=4){ // x = r * cos(phi), y = r * sin(phi) // use radian measure point(x_M + tickRadius * cos(PI/180*i), y_M + tickRadius * sin(PI/180*i)); } } int drawHand(int handPos) { color c = color(255, 204, 0); // Define RGB color 'c' stroke(c); // x = r * cos(phi), y = r * sin(phi) // use radian measure line(x_M, y_M, x_M + tickRadius * cos(PI/180*handPos), y_M + tickRadius * sin(PI/180*handPos)); // update handPos by one degree handPos++; return handPos; }
