moderngl
========
.. py:module:: moderngl
.. code-block:: python
import moderngl
window = ...
ctx = moderngl.create_context()
# store a ref to ctx
The module object itself is responsible for creating a :py:class:`Context` object.
.. py:function:: moderngl.create_context(require: int = 330, standalone: bool = False) -> Context
Create a ModernGL context by loading OpenGL functions from an existing OpenGL context.
An OpenGL context must exist. Call this after a window is created or opt for the windowless standalone mode.
Other backend specific settings are passed as keyword arguments.
Context sharing is known to not work properly, please avoid using it.
There is a paramter `share` for that to attempt to create a shared context.
:param int require: OpenGL version code
:param bool standalone: Headless flag
Example::
# Accept the current context version
ctx = moderngl.create_context()
# Require at least OpenGL 4.3
ctx = moderngl.create_context(require=430)
# Create a windowless context
ctx = moderngl.create_context(standalone=True)
.. py:function:: moderngl.create_standalone_context(...) -> Context
Deprecated, use :py:func:`moderngl.create_context()` with the standalone parameter set.
.. py:function:: moderngl.get_context() -> Context
Returns the previously created context object.
Example::
# my_app.py
from moderngl import create_context
ctx = create_context(...)
# my_renderer.py
from moderngl import get_context
class MyRenderer:
def __init__(self):
self.ctx = get_context()
self.program = ...
self.vao = ...
