<p></p> <p><b>新規ページ</b></p><div>This page is to document several issues I've discovered/thought-of for dependency graphs. Several applications use them quite heavily (maya and houdini both come to mind) and I've thought of several issues that might<br /> be worth considering.<br /> <br /> The idea has come up of having a dependency graph that uses RNA properties.<br /> This would be quite a bit more complex then what we have now, I suspect,<br /> which is why I wrote this page. I'm assuming an RNA-based dependency graph would be based on mapping RNA structs to nodes and having the properties map to node inputs and outputs (this is how other apps seem to work). A final design would probably be different, but might still might benefit from some of the ideas on this page.<br /> <br /> =Definitions=<br /> Node: An entity in the graph, that has incoming and outcoming connections. All the nodes in the graph are executed in order.<br /> <br /> =Channel-based dependencies=<br /> Nodes might reference independent parts of each other, perhaps even in<br /> a cyclic manner. This should be handled well, perhaps by basing dependencies<br /> on the input connections; from a graphing point of view this might be like having each input be it's own little subnode, with groups of subnodes belonging to the same &quot;node&quot; associated with each other, perhaps with their own dependancy relationships.<br /> <br /> =Nondestructive Editing=<br /> One of the problems with maya, is that once you connect a channel with something (like certain constraints) you lose the original data. This<br /> makes me thinks you'd need some system to procedurally edit data.<br /> Maybe specific RNA properties would have special setters just for the graph system, that doesn't actually set the property but a procedural version of it (e.g. have a split between 'final' and user-set versions of properties.<br /> Sortof how modifiers and constraints work).</div>
