# modeling-2: Model : displaying two pyramids

# The pyramid model we create in the previous lesson was still in a scratchy form :
# all faces and vertices were python object, and were rendered individually, which
# implies a performance lost.

# In this lesson we'll see how to "compile" our pyramid model into a Model,
# and how to use it in the same way we use the sword model in the basic-1.py lesson.


# Imports and inits Soya.

import sys, os, os.path, soya

soya.init()
soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data"))

# Creates the scene.

scene = soya.World()

# Loads the pyramid model that we have created and saved in the modeling-basic-1.py
# lesson.
# We ask Soya for s Model called "pyramid", though it does not exist ! Remember, we have
# created a World pyramid, not a Model. In this case, Model.get automatically loads the
# pyramid World, compiles it into a Model, and saves the Model in the "./models" directory
# in soya.path[0].
# Soya Model compilation behaves like Python compilation of .py files in .pyc : whenever
# the World file is changed, Model.get will recompile it automatically.
# You can also use the World.to_model() to compile a World into a Model without saving it.

# Soya Model compilation supports only triangles and quads; points, lines or more complex faces are
# not supported.

pyramid_model = soya.Model.get("pyramid")

# Creates a Body in the scene, that displays the pyramid.

pyramid1 = soya.Body(scene, pyramid_model)

# Moves and rotates the pyramid (for a better view)

pyramid1.x = -0.7
pyramid1.rotate_y(60.0)

# Creates a second pyramid. Contrary to World, Model model can be displayed several
# time at different position.
# Soya separates the model part (the Model) from the position part (the Body).

pyramid2 = soya.Body(scene, pyramid_model)
pyramid2.x = 0.8
pyramid2.rotate_y(45.0)

# Creates a light.

light = soya.Light(scene)
light.set_xyz(1.0, 0.7, 1.0)

# Creates a camera.

camera = soya.Camera(scene)
camera.set_xyz(0.0, -0.6, 2.0)
soya.set_root_widget(camera)

soya.MainLoop(scene).main_loop()
