Turtl3

I think all python devs know the turtle library, but this python file brings turtle to another DIMENSION!!! Welcome to turtl3.py, a 3D turtle library. To start, create a Turtl3 object and call its loop() method with two methods for the start, update and draw event.

def start(t):
    pass

def update(t):
    pass

def draw(t):
    pass

t3 = Turtl3(800, 600)
t3.loop(start, draw, update)

Additionally, other fields of the Turtl3 instance can be set.

In start, you can define which keys to observe by calling either the listen_for_key() or the listen_for_keys() function.

turtl3.listen_for_keys(["w", "a", "s", "d"])

It is also possible to load an .obj wavefront model file. Simply do:

model = load_model("monkey.obj")
model.move(Vec3(0, 0, 10))

Since there is no lighting, I recommend to enable the wireframe by calling

t3.set_wireframe_overlay(True)

In the draw loop, a model or a cube can be rendered like that:

t3.cube(0, 0, -2, 5, 5, 5, colors=[Vec3(0, 0, 0), Vec3(1, 0, 0), Vec3(0, 1, 0), Vec3(0, 0, 1), Vec3(1, 1, 0), Vec3(0, 1, 1)])
t3.model(model)

The colors parameter sets the colors for the individual faces of the cube, but the parameter color can also be used, to set all the faces at once.

In update or draw, the keys can be checked to update the scene:

def update(t3: Turtl3):
    if is_pressed("space"):
        t3.move(0, 1, 0)
    if is_pressed("Shift_L"):
        t3.move(0, -1, 0)
    if is_pressed("w"):
        t3.move(-1, 0, 0)
    if is_pressed("a"):
        t3.move(0, 0, -1)
    if is_pressed("s"):
        t3.move(1, 0, 0)
    if is_pressed("d"):
        t3.move(0, 0, 1)
    if is_pressed("Up"):
        t3.rotate(1, 0, 0)
    if is_pressed("Down"):
        t3.rotate(-1, 0, 0)
    if is_pressed("Left"):
        t3.rotate(0, 1, 0)
    if is_pressed("Right"):
        t3.rotate(0, -1, 0)

IMPORTANT Only keys that where specified via either the listen_for_key() or the listen_for_keys() function can be checked!

Anyways, have fun with this stupid little thing! :D
