Decora <> Open Shading Language?

[Philipp Dörfler]

Given that they are mentioning the GPU in the roadmap at least indicates that it would possible to write such a backend. Thus my suggestion to take advantage of the intermediate bytecode emitted by OSL and to convert this bytecode to D3D and OpenGL shaders using Decora.

I'm neither a Decora nor an OSL expert and I especially do not know how complex OSL (or that subset of OSL) is or if it is suitable for the purposes Decora is aimed at. For example: Decora allows to call getEffect() [1]. I just assume there is a comparable way of doing that in OSL.
Having said that, I imagine it would be pretty awesome to have "NEW: Support for Open Shading Language in Decora" in the feature list for JavaFX 42 given that JavaFX 2 seems to be all about re-using existing knowledge and not having to learn new languages.

Just my six cent,
