Improve the loader performance about threejs-collada HOT 4 CLOSED

A lot of time is being spent parsing the strings, even though the actual values may not be used. And the parsing generates a lot of garbage (_strToStrings in particular). Wouldn't it be better to parse the data lazily, only when needed?

Something like a388d74. But extended to all the nodes, not just <source>.

If any data from the collada file is not used, it shouldn't even be in there. Well formatted collada files will use all of the arrays. So I'd rather parse the string immediately (not sure how to do this without garbage) than hold on to the (huge) strings for a long time. I'd expect a few huge typed arrays should not be too much overhead fr the garbage collector

I don't think it's possible to efficiently load COLLADA in javascript. It's about the worst asset format there is. Giving up on this.
