Description
Processing Basics and Drawing Overview Processing’s coordinate system is in quadrant one except y values are reflected across y axis -positive y values are increasing down the window -the top left corner of the sketch is (0, 0) -the center of the sketch is (width/2, height/2) -the bottom right corner of the sketch is (width, height) void setup-run only once in the beginning void draw-method called 60fps which draws current frame on screen over and over frame rate-used to control an application -can be used as a time -the higher the frame rate, the smoother Shapes point (x, y); line(x1, y1, x2, y2); -x1, y1 arguments are the location of the start point of the line -x2, y2 arguments are the location of the endpoint of the line ellipse(x, y, width, height); -x, y arguments are the location of the center of the ellipse -width, height arguments are how wide and tall the ellipse will be around the center however, if ellipseMode(CORNER); is specified before drawing ellipse, properties will be the same as rect -ellipseMode(CENTER); does not need to be specified unless you want to override an ellipse drawn with ellipseMode(CORNER); rect(x, y, width, height); -x, y arguments are the location of the top left corner of the rectangle -width, height arguments are how wide (right) and how tall (down) the rectangle will be however, if rectMode(CENTER); is specified before drawing rect, properties will be the same as ellipse -rectMode(CORNER); does not need to be specified unless you want to override a rect drawn with rectMode(CENTER); triangle(x1, y1, x2, y2, x3, y3); -x, y arguments corresponds to each point in the triangle quad(x1, y1, x2, y2, x3, y3, x4, y4); -x, y arguments corresponds to each point in the quad arc(x1, y1, width, height, start, stop ); -the first four arguments are just like an el
