Public Class methods

new(app, flags) {|theGLVisual| ...}

Construct default visual

supported?(app)

Test if OpenGL is possible, and what level is supported. Because of remote display capability, the display server may support a different level of OpenGL than the client; it may even support no OpenGL at all! This function returns the lesser of the client support level and the display server support level.

Public Instance methods

accelerated?()

Return true if hardware-accelerated

bufferSwapCopy?()

Return true if this visual "swaps" by copying instead of flipping buffers.

doubleBuffered?()

Return true if double-buffered

stereo?()

Return true if stereo
