GLMAXVIEWPORTS

GLMAXVIEWPORTS is a constant in the OpenGL API that defines the maximum number of viewports that can be supported by an implementation. A viewport is a rectangular region within the window where OpenGL renders images. The value of GLMAXVIEWPORTS can be queried using the glGetIntegerv function, which returns the maximum number of viewports that can be defined for a single context. This constant is particularly relevant in advanced rendering techniques such as multi-viewport rendering, where multiple viewports are used to render different parts of a scene or to implement stereoscopic rendering. The actual value of GLMAXVIEWPORTS can vary depending on the hardware and software capabilities of the system. It is important for developers to check this value to ensure that their applications can handle the maximum number of viewports supported by the hardware.
