Does jMonkey support EXT_texture_from_pixmap?

Troubleshooting General Help
1

is the extension EXT_texture_from_pixmap is supported in JMonkey?



if not is there any plan?

From the GL extension registry:

    The functionality of this extension is similar to WGL_ARB_render_texture.
    However, the purpose of this extension is not to provide
    "render to texture" like functionality but rather the ability to bind
    an existing X drawable to a texture. Though, there is nothing that
    prohibits it from being used for "render to texture".


I suggest you check out the TextureRenderer class of jME as it can "bind an existing X drawable to a texture", which seems like what you're looking for. I don't think jME will support it (and I am not even sure if LWJGL does) since it is linux specific.

I will check it

I have checked the class, I can't see any way on how to bind a X Drawable to texture.



my purbose on EXT_texture_from_pixmap is we on LG3D, may switch to JME (as lg3d-wonderland will do)

and we want use it to bind all manage X APP to textures so that we don't need to copy the content of the drawable to texture each the content change as we now do? this extension do the copy by the hardware!!

compiz use EXT_texture_from_pixmap extension.



EXT_texture_from_pixmap is not only for linux it is also on solaris… and any OS which use Xorg.



what I need a texture which support this extension and then I can attach this texture to any geometry I want as needed.



I can write an extension for this on linux if this possible, I just need guidelines as I have not use JMonkey or lwjgl before!

I just did a quick check and it doesn't seem like LWJGL supports it, you might want to do more research on the issue. It might be possible with context sharing, but I am not sure.
