C++ custom tool SDK programming tip

[scaron]

as far as caching goes the Geometry class provides PutCache and GetCache...

but with a plugin ahmidou's where the point positions are changing constantly it might not be useful. unless the cache can be some how partially and incrementally updated. i doubt that though

I just saw the Put/GetCache yesterday, this might be usefull for a relax+shrinkwrap brush.
Anyway the tool is already faster than push or smooth + weightMap, but I'm still testing which method would be faster.
Piotrek you're right and it make sense, there is some point where rebuilding the acceleration tree become slower than the pickBuffer.
It also need to be rebuilt for the GetClosestLocationsWithinRadius which I'm forced to use every drag update...
