Method Details

getInfo

public static GLUtils.Info getInfo()

Queries GPU/OpenGL info via a 1x1 offscreen drawable. The result is cached after the first call, since neither the active GPU nor its driver change mid-session. Note that on hybrid-graphics systems (e.g., NVIDIA Optimus, AMD Switchable Graphics, macOS automatic graphics switching) this reports whichever GPU the OS bound to this JVM process, not necessarily every GPU installed

Returns:

the (cached) result of the query; GLUtils.Info.available() is false if no GL context could be created
