Pixel Art of ALIEN MONSTERS#
Here we use pyvista.Box()
to make pixel art.
Pixel string source
and license.
from __future__ import annotations
import pyvista as pv
from pyvista.demos import logo
Convert pixel art to an array#
alien_str = """

Define function to draw pixels#
Define a helper function to add pixel boxes to plotter.
def draw_pixels(plotter, pixels, center, color):
bounds = [
center[0] - 1.0,
center[0] + 1.0,
center[1] - 1.0,
center[1] + 1.0,
-10.0,
+10.0,
]
for rows in pixels:
for pixel in rows:
if pixel:
box = pv.Box(bounds=bounds)
plotter.add_mesh(box, color=color)
bounds[0] += 2.0
bounds[1] += 2.0
bounds[0] = center[0] - 1.0
bounds[1] = center[0] + 1.0
bounds[2] += -2.0
bounds[3] += -2.0
return plotter
Now you can plot a pixel art of ALIEN MONSTERS.
# Display MONSTERS
p = pv.Plotter()
p = draw_pixels(p, alien, [-22.0, 22.0], 'green')
p = draw_pixels(p, alien, [0.0, 22.0], 'green')
p = draw_pixels(p, alien, [22.0, 22.0], 'green')
p = draw_pixels(p, alien, [-22.0, 0.0], 'blue')
p = draw_pixels(p, alien, [0.0, 0.0], 'blue')
p = draw_pixels(p, alien, [22.0, 0.0], 'blue')
p = draw_pixels(p, alien, [-22.0, -22.0], 'red')
p = draw_pixels(p, alien, [0.0, -22.0], 'red')
p = draw_pixels(p, alien, [22.0, -22.0], 'red')
text = logo.text_3d('ALIEN MONSTERS', depth=10.0)
