Todays daily graphic I'm getting familiar with grids (in shoebot), Vector maths from the planar library .. this started from the grid example from shoebot / nodebox.
Shoebot Code Below the fold
""" Grid of arrows that point towards the mouse pointer. Uses planar library for Vec2, angles. """ # Based on grid->colorgrid example from shoebot # # This is also basically a remake / rip / inspired # one of the examples made in the LGM 2014 workshop # if that was you let me know so I can add it to # shoebot 🙂 import random from planar import Vec2, Affine size(625, 625) # Create a color Grid. # This example also shows of the HSB color mode that allows # you to select colors more naturally, by specifying a hue, # saturation and brightness. colormode(HSB) def draw(): random.seed(0) # Set some initial values. You can and should play around with these. h = 0 s = 0.5 b = 0.9 a = .5 # Size is the size of one grid square. size = 50 # Create a grid with 10 rows and 10 columns. The width of the columns # and the height of the rows is defined in the 'size' variable. for x, y in grid(WIDTH / size, HEIGHT / size, size, size): reset() # Using the translate command, we can give the grid some margin. translate(size,size) # Increase the hue while choosing a random saturation. # Try experimenting here, like decreasing the brightness while # changing the alpha value etc. h+=.01 s=random.random() pos=Vec2(x-MOUSEX, y-(MOUSEY - size)) # Set this to be the current fill color. fill(h, s, b, a) # Draw a angle that is one and a half times larger than the rotate(180-pos.angle) arrow(x, y, size*1.5)
