Class GLXNVMultiGPUContext

java.lang.Object

org.lwjgl.opengl.GLXNVMultiGPUContext

public final class GLXNVMultiGPUContext
extends java.lang.Object

Native bindings to the GLX_NV_multigpu_context extension.

This extension allows the creation of an OpenGL context in a multi-GPU environment with a specified multi-GPU strategy (known as SLI mode) which takes precedence over process-wide multi-GPU mode settings.

The multi-GPU mode denotes vendor specific techniques to allow distributed rendering on multiple GPUs, further called AFR (alternate frame rendering) and Multicast (as defined in NV_gpu_multicast).

OpenGL supports multiple contexts. The semantics of switching contexts is generally left to window system binding APIs such as WGL, GLX and EGL. The extension GLX_NV_multigpu_context allows to specify a preferred multi-GPU rendering mode per context, thus context switching can also switch the current multi-GPU rendering mode.

In addition to the modes described above, this extension allows creating contexts in single mode to force all rendering to be done on a single GPU, and multi-display multicast mode to allow multicast rendering on a multi-display configuration where displays attached to multiple GPUs are linked together in a desktop configuration spanning multiple GPUs.

The implementation is platform dependent and the actual multi-GPU rendering mode of the created context may vary on different hardware and operation system platforms.

Requires GLX14 and GLX_ARB_create_context.
