SDL.Video.OpenGL

A set of default options for OpenGLConfig

defaultOpenGL = OpenGLConfig
  { glColorPrecision = V4 8 8 8 0
  , glDepthPrecision = 24
  , glStencilPrecision = 8
  , glMultisampleSamples = 1
  , glProfile = Compatibility Normal 2 1
  }

Configuration used when creating an OpenGL rendering context.

A created OpenGL context.

Create a new OpenGL context and makes it the current context for the window.

Throws SDLException if the window wasn't configured with OpenGL support, or if context creation fails.

See SDL_GL_CreateContext for C documentation.

The profile a driver should use when creating an OpenGL context.

The mode a driver should use when creating an OpenGL context.

Set up an OpenGL context for rendering into an OpenGL window.

Throws SDLException on failure.

See SDL_GL_MakeCurrent for C documentation.

Delete the given OpenGL context.

You must make sure that there are no pending commands in the OpenGL command queue, the driver may still be processing commands even if you have stopped issuing them!

The glFinish command will block until the command queue has been fully processed. You should call that function before deleting a context.

See SDL_GL_DeleteContext for C documentation.

Get the size of a window's underlying drawable area in pixels (for use with glViewport).

It may differ from windowSize if window was created with windowHighDPI flag.

Replace the contents of the front buffer with the back buffer's. The contents of the back buffer are undefined, clear them with glClear or equivalent before drawing to them again.

See SDL_GL_SwapWindow for C documentation.

The swap interval for the current OpenGL context.

Get or set the swap interval for the current OpenGL context.

This StateVar can be modified using $= and the current value retrieved with get.

See SDL_GL_SetSwapInterval and SDL_GL_GetSwapInterval for C documentation.
