lpugl Examples

• example01.lua

  Simple example using the Cairo rendering backend. The Cairo backend requires OOCairo.

  

• example02.lua

  Simple example using the OpenGL rendering backend. This example uses LuaGL Lua binding (see also enhanced LuaGL rockspec).

  

• example03.lua

  A mini game demonstrating smooth animations using pre-rendered cairo surfaces.

  

• example04.lua

  Same mini game as in example03.lua but here the OpenGL backend is used. This example uses lua-nanovg as vector graphics rendering library for OpenGL.

  

• example05.lua

  An interactive demonstration for partial redrawing using the cairo rendering backend.

  

• example06.lua

  Partial redraw demonstration similar to example05.lua using the OpenGL backend with lua-nanovg.

  

• example10.lua

  This examples demonstrates the usage of the Notify C API in a multithreading scenario.

  LPugl world objects implement the Notify C API, see src/notify_capi.h, i.e. the world object has an an associated meta table entry _capi_notify delivered by the C API function notify_get_capi() and the associated C API function toNotifier() returns a valid pointer for a given LPugl world object.

  In this example the Notify C API is used to notify the event loop by calling world:awake() each time a message is added by another thread to a mtmsg buffer object.

  This is done by connecting the LPugl world object as a notifier object to the mtmsg buffer object.
