What I want is a shared grammar that captures a sizable chunk of reality. Beyond multiple instancing I would like to also express geometry parametrically and I'd like to express linear constraints,
I thought about that problem for a long time, and concluded that it was not a grammar problem. You can represent any relations like that in a programming language which is embedded into the viewer.
So the grammar you might want is "Python" or "Ruby" or some other form of language that is eval()'able at run-time (assuming the viewer is in C or something that is actually fast enough to handle the system).
The grammar needs to hand over the parameters concerned to a language stub that can then calculate any such relationships between elements in the model. The language is Turing-complete, whereas grammar isn't.
I'm posting too much to the list, so I'm going to go quiet again. -- [EMAIL PROTECTED] _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
