Package pyglet.gl

OpenGL and GLU interface.

This package imports all OpenGL, GLU and registered OpenGL extension functions. Functions have identical signatures to their C counterparts. For example:

from pyglet.gl import *

# [...omitted: set up a GL context and framebuffer]
glBegin(GL_QUADS)
glVertex3f(0, 0, 0)
glVertex3f(0.1, 0.2, 0.3)
glVertex3f(0.1, 0.2, 0.3)
glEnd()

OpenGL is documented in full at the OpenGL Reference Pages.

The OpenGL Programming Guide is a popular reference manual organised by topic. The free online version documents only OpenGL 1.1. Later editions cover more recent versions of the API and can be purchased from a book store.

The following subpackages are imported into this "mega" package already (and so are available by importing pyglet.gl):

pyglet.gl.gl: OpenGL
pyglet.gl.glu: GLU
pyglet.gl.gl.glext_arb: ARB registered OpenGL extension functions
pyglet.gl.gl.glext_missing: ARB registered OpenGL extension functions not included in the ARB C header

These subpackages are also available, but are not imported into this namespace by default:

pyglet.gl.glext_nv: nVidia OpenGL extension functions
pyglet.gl.agl: AGL (Mac OS X OpenGL context functions)
pyglet.gl.glx: GLX (Linux OpenGL context functions)
pyglet.gl.glxext_arb: ARB registered GLX extension functions
pyglet.gl.glxext_nv: nvidia GLX extension functions
pyglet.gl.wgl: WGL (Windows OpenGL context functions)
pyglet.gl.wglext_arb: ARB registered WGL extension functions
pyglet.gl.wglext_nv: nvidia WGL extension functions

The information modules are provided for convenience, and are documented below.

Function Details

get_current_context

get_current_context()

Return the active OpenGL context.

You can change the current context by calling Context.set_current.

Returns:: Context: the context to which OpenGL commands are directed, or None if there is no selected context.

Deprecated: Use current_context
