DX 7 does provide stereo support.
it can be tested for ( in DX, not Java ) via the ddcaps.dwcaps2 caps
bits, when DDCAPS2_STEREO is set the ddcaps.dwSVCaps bit is enabled to
indicate the card supports stereo mode. The driver can do stereo in at
least one mode other than the current mode. The application can use
IDirectDraw7::GetDisplayMode or IDirectDraw7::EnumDisplayModes to get
per-mode stereo information.
if stereo support exists, you can create a complex flipping chain that
supports stereo. see the DX 7 SDK for more data.
support for this is not included in the DX 8 interfaces.
please mail [EMAIL PROTECTED] if this is important for Java3D since
this feature is actively being considered for DX 9.
