System.Boolean |
SwapInterval
Gets or sets a positive integer in the range [1, n), indicating the number of DisplayDevice refreshes between consecutive SwapBuffers() calls. The maximum value for n is implementation-dependent. The default value is 1. Invalid values will be clamped to the valid range.
Declaration
int SwapInterval { get; set; }

Methods
LoadAll()
Loads all OpenGL entry points. Requires this instance to be current on the calling thread.

Makes the GraphicsContext current in the calling thread.
Declaration
void MakeCurrent(IWindowInfo window)
Parameters
Type | Name | Description |
---|---|---|
IWindowInfo | window | An OpenTK.Platform.IWindowInfo structure that points to a valid window. |

OpenGL commands in one thread, affect the GraphicsContext which is current in that thread.
It is an error to issue an OpenGL command in a thread without a current GraphicsContext.
SwapBuffers()
Swaps buffers, presenting the rendered scene to the user.
Declaration
void SwapBuffers()
Update(IWindowInfo)
Updates the graphics context. This must be called when the region the graphics context is drawn to is resized.
Declaration
void Update(IWindowInfo window)
Parameters
