I /think/ I've found a language that might be suitable; at any rate, it...

(1) shares the design goal of providing both declarative and procedural

(2) has native support for /all/ of the domain-specific basic types we
would need (most notably vectors and colours);

(3) already covers a major subset of POV-Ray's language domain; and

(4) is already established, /specifically/ in the domain of 3D rendering.

Have a look at NVIDIA's Material Definition Language (MDL):



I think all we'd have to do is provide some intrinsic data types for
geometric shapes and some odds & ends (such as light sources, global
settings, etc.), and we'd have a useful Scene Description Language.

Is it pretty to use? Don't know yet.

Can we get Nvidia's implementation for free? Don't know yet, but I'd
doubt it. The language specs are open though, so we could write our own
