April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.


For examples and more explanations, see the module level docs.

class OpenGLDisplay(Axon.AdaptiveCommsComponent.AdaptiveCommsComponent)

OpenGLDisplay(...) -> new OpenGLDisplay component

Use OpenGLDisplay.getDisplayService(...) in preference as it returns an existing instance, or automatically creates a new one.

Or create your own and register it with setDisplayService(...)

Keyword arguments (all optional):



Methods defined here


You should be using the inbox/outbox interface, not these methods (except construction). This documentation is designed as a roadmap as to their functionalilty for maintainers and new component developers.

__init__(self, **argd)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

calcPow2Size(self, size)

Calculates the power of 2 dimensions for a given size.

doPicking(self, pos)

Uses OpenGL picking to determine objects that have been hit by mouse pointer. see e.g. OpenGL Redbook


Draws all registered OpenGL components with their set transformation matrix.


Draws all surfaces of registered pygame components on top of everything else.


Returns a unique number.


Handles pygame input events.

handleOGLComponentEvents(self, events)

Prepare and send input events for OpenGL components.

handlePygameComponentEvents(self, events)

Prepare and send input events for pygame components.

handleRequest_DISPLAYREQUEST(self, message)

handleRequest_EVENTSPYREQUEST(self, message)

handleRequest_OGL_DISPLAYREQUEST(self, message)

handleRequest_WRAPPERREQUEST(self, message)


Handles service requests.


Main loop.


Sets projection matrix.

surfacePosition(self, surface)

Returns a suggested position for a surface. No guarantees its any good!


Draws all components, updates screen, clears the backbuffer and depthbuffer .

updatePygameTexture(self, surface, pow2surface, texname)

Converts the surface of a pygame component to an OpenGL texture.


Got a problem with the documentation? Something unclear that could be clearer? Want to help improve it? Constructive criticism is very welcome - especially if you can suggest a better rewording!

Please leave you feedback here in reply to the documentation thread in the Kamaelia blog.
