COLORS We choose the colors that we are going to use and put name to them

#

FUNCTION We elaborate a function with three variables: the position, the size and the name of the object (cube)

#

def MaBoite(_position, _taille, _nom):
    bpy.ops.mesh.primitive_cube_add(radius=1, location=_position)
    bpy.ops.transform.resize(value=_taille)
    bpy.context.object.name = _nom

#

THE 3 FACES Creation of the 3 faces of the model (Face A, Face B and Face C)

for j in range(0, 1):
    MaBoite((0, 0.05, -0.95), (11.95, 11.95, 0.05), "FACE XY")

for j in range(0, 1):
    MaBoite((-12, 0, 11), (0.05, 12, 12), "FACE YZ")

for j in range(0, 1):
    MaBoite((0, -11.95, 11), (11.95, 0.05, 12), "FACE XZ")

#

FACE A (XZ) We start doing the extrusions of the Face A

THICK EXTRUSIONS

Level 1 - BLACK

We create two thick and fixed extrusions in level 1

for j in range(0, 1):
    MaBoite((4, 0.05, 0), (4, 11.95, 1), "BLACK level 1 XZ 1")

#

We add the black color to the extrusions

    mesh = bpy.context.object.data
    mesh.materials.clear()
    mesh.materials.append(mat_black)

    MaBoite((-10, 0.05, 0), (2, 11.95, 1), "BLACK level XZ 2")

    bpy.ops.transform.translate(value=(1 / 3, 0, 0))

#

We add the grey color to the extrusions

    mesh = bpy.context.object.data
    mesh.materials.clear()
    mesh.materials.append(mat_grey)

#

As we said they are not fixed, they may vary in z direction between levels 2 and 3

bpy.data.objects["barres minces -45"].location.z += randint(2, 4)

bpy.data.objects["barres minces 25"].location.z += randint(16, 22)

#

FACE B (YZ) - We continue with the extrusions of the Face B

#

EXTRUSIONS 1x1

#

FONCTION - We add a new function to make triangles from the extrusions in this face

     - From every 1x1 extrustion we can make 4 squares divided in 2 triangles each one of them to make the diferent random possibilities
     - We start doing the two triangles with different position

#

TRIANGLE 1

#

def Triangle1():

#

we create some vertex to join them and define faces

    mesVertices = [(0, 0, 0), (0, 1, 0), (0, 1, 1), (24, 0, 0), (24, 1, 0), (24, 1, 1)]
    mesFaces = [(0, 1, 2), (1, 2, 5, 4), (0, 1, 4, 3), (0, 2, 5, 3), (3, 4, 5)]

#

we create the mesh and the object

    monMesh = bpy.data.meshes.new("triangleMesh")
    monObjet = bpy.data.objects.new("1", monMesh)

#

we link the object to the scene

    maScene = bpy.context.scene
    maScene.objects.link(monObjet)

#

“fill” the mesh with the information of the vertices and faces

    monMesh.from_pydata(mesVertices, [], mesFaces)

    return monObjet

#

TRIANGLE 2

#

def Triangle2():
    mesVertices2 = [(0, 0, 0), (0, 1, 1), (0, 0, 1), (24, 0, 0), (24, 1, 1), (24, 0, 1)]
    mesFaces2 = [(0, 1, 2), (1, 2, 5, 4), (0, 1, 4, 3), (0, 2, 5, 3), (3, 4, 5)]
    monMesh2 = bpy.data.meshes.new("triangleMesh2")
    monObjet2 = bpy.data.objects.new("2", monMesh2)
    maScene2 = bpy.context.scene
    maScene2.objects.link(monObjet2)
    monMesh2.from_pydata(mesVertices2, [], mesFaces2)

    return monObjet2

#

We create a function where we are going to have both triangles with two variables (the position and the name):

#

def TriangleCube(_position, _nom):
    bpy.ops.object.select_all(action="DESELECT")

#

We tell the program to do copies of the triangles together 4 times (when the angle is 0, 90, 180 and 270º) We say too that just can appear one of the two triangles every time, and the program can choose it in a random way.

    for angle in range(0, 271, 90):
        object = random.choice([Triangle1, Triangle2])()
        object.select = True
        object.name = _nom
        object.rotation_euler[0] = radians(angle)

#

We add this parameter to change the position

    bpy.ops.transform.translate(value=_position)

#

Level 4 to 8 - YELLOW

We create the first yellow “TriangleCube”

for i in range(0, 1):
    TriangleCube((-12, -11, 0), "triangles")

#

We choose the position which can vary between levels 4 and 8

    Yellow2H = randint(6, 14)
    bpy.data.objects["triangles"].location.z += Yellow2H

#

We add the yellow color to every triangle

    bpy.data.objects["triangles"].active_material = mat_yellow
    bpy.data.objects["triangles.001"].location.z += Yellow2H
    bpy.data.objects["triangles.001"].active_material = mat_yellow
    bpy.data.objects["triangles.002"].location.z += Yellow2H
    bpy.data.objects["triangles.002"].active_material = mat_yellow
