ModernGL Objects¶

Methods¶

Attributes¶

Context Flags¶

Context flags are used to enable or disable states in the context. These are not the same enum values as in opengl, but are rather bit flags so we can or them together setting multiple states in a simple way.

These values are available in the Context object and in the moderngl module when you don’t have access to the context.

import moderngl

# From moderngl
ctx.enable_only(moderngl.DEPTH_TEST | moderngl.CULL_FACE)

# From context
ctx.enable_only(ctx.DEPTH_TEST | ctx.CULL_FACE)

Primitive Modes¶

Texture Filters¶

Also available in the Context instance including mode details.

Blend Functions¶

Blend functions are used with Context.blend_func to control blending operations.

# Default value
ctx.blend_func = ctx.SRC_ALPHA, ctx.ONE_MINUS_SRC_ALPHA

Blend Function Shortcuts¶

Blend Equations¶

Used with Context.blend_equation.

Other Enums¶

Examples¶

ModernGL Context¶

import moderngl
# create a window
ctx = moderngl.create_context()
print(ctx.version_code)

Standalone ModernGL Context¶

import moderngl
ctx = moderngl.create_standalone_context()
print(ctx.version_code)

ContextManager¶

context_manager.py

example.py

from context_manager import ContextManager

ctx = ContextManager.get_default_context()
print(ctx.version_code)
