JavaFX 3D on older GPUs

[Adam Granger]

So no support to provide software rendering fallback on my Samsung NC10 (2008) :( ? I just want to play around with some 3D stuff on long train journeys!

I don't fully understand the layers involved, perhaps someone could explain.... 

My understanding... JavaFX will get an openGL implementation from the OS, and that implementation will either be hardware driver provided or software emulation or some mix?  it will then use the OpenGL to work out whether various features, shader API versions etc. exist... if something isn't supported <BOOM>

Is there no way prism can implement a fallback using lower version of shader model, or is this just two complex? Or is it really the responsibility of the openGL provider - e.g. Mesa to provide software fallback?

Regards,

Adam.
