// Class : GraphicsPipe
|
|
// Description : An object to create GraphicsWindows that share a
|
|
// particular 3-D API. Normally, there will only be one
|
|
// GraphicsPipe in an application, although it is
|
|
// possible to have multiple of these at once if there
|
|
// are multiple different API's available in the same
|
|
// machine.
|
|
//
|
|
// Often, the GraphicsPipe corresponds to a physical
|
|
// output device, hence the term "pipe", but this is not
|
|
// necessarily the case.
|
|
//
|
|
// The GraphicsPipe is used by the GraphicsEngine object
|
|
// to create and destroy windows; it keeps ownership of
|
|
// the windows it creates.
|
|
//
|
|
// M. Asad added new/interim functionality where GraphicsPipe
|
|
// now contains a device interface to directx/opengl which
|
|
// will be used to handle multiple windows from same device.
