[java] Direct3D in Java

Direct3D is windowsspecific...so you can't use it directly with java

from the top of my head: you can select if java3d should use openGL or direct3D...so on windowsmachines you might already be using direct3D without knowing.

hope that helps

Why exactly do you have to use D3D? If you're just wanting to use a lower-level API instead of J3D then you'll be better off using OpenGL via LWJGL.

Seconded.

Thank you guys for help.

I wanted to use Direct3D because I need to load from .X file mesh-object and use it. How to do it in Java3D?

You can use Blender with plugins to load the .x file and then export it to a different format. I don't know if Java3D supports any type of model loading, but that would be the way. Another program that could convert model types is MilkShape 3D.

If you switch to jMonkey Engine (jME), they support multiple model formats. I don't think .x is one, but they do support .OBJ among others.

J3D has an API to write loaders, so if there isn't one already, you can write yours (and then contribute it to the community =). But I don't know much about the .x extension, never used it before, so I can't really comment on how good that would be.

Stick to low level APIs, such as LWJGL or JOGL, if you're dead set about using the ".x" file format. It may take a while, but you'll be able to come up with a good loader. If you're willing to switch formats, using export through Blender or any other software, then you might consider Capn's suggestion. JME has a lot of support for many popular formats.
