Hi Young, Brad:
A property is added in the v1.2.1 DirectX release
(not in v1.2.1 beta2)
to work for legacy Voodoo card as follows:
Direct3D Driver selection
--------------------------
By default, the first driver found with monitor matching
the display driver is use during DirectDrawEnumerateEx()
for all DDENUM_ATTACHEDSECONDARYDEVICES,
DDENUM_DETACHEDSECONDARYDEVICES and DDENUM_NONDISPLAYDEVICES.
This order can be found by using -Dj3d.debug=true property
during Java startup.
In order to use 3D only graphics card such as Voodoo1/2
A new property is add
-Dj3d.d3ddriver=idx
where idx is the order DirectX enumerate its driver
using DirectDrawEnumerateEx(). This number start with 1.
This will force Java3D to use the driver specific by user
(may fail if the driver is not compatible with display)
For a typical setup of a 3D only card attach to
a graphics card in a single monitor system, use idx=2.
This will automatically toggle to fullscreen hardware
accelerated mode since if the 3D card support 3D only.
Thanks.
- Kelvin
