After Dark

Ludivine Lechat's great artwork in the NodeBox Core Image library.

NodeBox source code:

coreimage = ximport("coreimage")
 
c = coreimage.canvas(500, 700)
 
images = ["1.tif", "2.tif", "3.tif", "4.tif", "5.tif"]
images_selected=[choice(images)]
images_selected.append(choice(images))
 
# The bluish radial background.
c.layer_fill(color(0.2, 0.2, 0.0))
l = c.layer_fill(color(0.8,0.8,0.4))
m = l.mask.layer_radial_gradient()
m.scale(1.5)
m.blend(30, mode="hue")
l = c.layer_fill(color(0.5,0.0,1.0))
l.blend(60, mode="hue")
l.mask.layer_linear_gradient()
 
# Draw 15 flowers.
for i in range(15):
 
    img = choice(images_selected)    
    l = c.layer(img)
    
    # It grows from the bottom.
    l.origin_bottom_center()
    l.x = i*40
    l.y = c.h + random(150)

        l.flip_horizontal()
    
    l.rotate(-i*2)
    s = random(0.5,1.5)
    l.scale(s)
    l.blend(s)
    
    # Apply green coloring to the layer,
    l.filter_levels(r=0.5, g=0.75+random(-0.1,0.1), b=0)
    
    # Filter effects:
    # deeper contrast, coloring,
    # and random twirling,
    if random() > 0.5:
        l.filter_twirl(angle=i*100, dy=i*10)

# The higher a flower grows,
# the more bluish it becomes (it's night).
l = c.layer_fill(color(0.5,0.0,1.0))
l.blend(40, mode="hue")
l.mask.layer_linear_gradient()
