Both GKSGRAL and GKSGRAL-3D use the same 2D device drivers. Thus, any 2D device supported by GKSGRAL can also be driven from GKSGRAL-3D. In addition, GKSGRAL-3D supports the IBM 5080, TEKTRONIX 4235/6, and the MEGATEK WHIZZARD series (models 72xx and 33xx) which have 3D hardware transformations.
The list of devices supported may be found in the include file
