install:

pip install pyvdl matplotlib opencv-python numpy

init:

import pyvdl as vl
print(f'install pyvdl: {vl.__version__}')

create_obj:

class example(vl.obj):
    def __init__(self):
        self.color = (255, 255, 255)
    def render(self, x, y):
        return self.abs_(x, y) - 20 < 0

create_animation:

        self.form = lambda x : x
        self.t = 5
        self.obj_ = example()

render:

# obj
obj = example()
r = vl.render(obj)
vl.show(r)  # show render-obj: r, only works on pykernel
vl.save("test.png", r)  # save render-obj: r as "test.png"
# animation

Fast-mode:

# create

    i = x if x > 0 else -x
    j = y if y > 0 else -y
    return (i+j)//2
r = vl.fastRender(f, 250, 250)() # syntax: vl.fastRender(func, width, heigth, x=0, y=0)()
r = vl.toRgb(r)
vl.show(r) # show render-obj: r, only works on pykernel
vl.save("test.png", r)  # save render-obj: r as "test.png"
