for
those of you using DX on W2K, there is a perf issue wrt to agp/vidmem vertex
buffers that can inhibit perf on W2K.
using
the DX 8 runtime with DX 8 DDI drivers, and updating to W2K SP2
addresses this issue.
W9x
does not suffer from this issue.
the
fixes are built-in to WXP.
OpenGL and DirectX are 'immediate mode' 3D rendering APIs. OpenGL runs
on everything down to probably your toaster and DirectX runs on PCs and the
XBox pretty much exclusively. DirectX is slightly ahead of OpenGL 1.2 feature
wise (damned slow ARB), but since you are using Java3D as an abstraction -
don't concern yourself with such things. On the current Windows builds, I'm
finding the OpenGL version still a good bit faster than my DirectX runs on a
GeForce2 GTS running Windows 2000.
As
for which one to download - don't EVER take anyone's opinion. Download them
both and find out for yourself - your mileage may vary from everyone
elses.
