Generates preprocess data relating to connectivity between unobstructed space boundaries, to support connected region queries.
void generateConnectedRegionPreprocessFor(const iShape& shape, const char *const* options);
|shape||The shape for which connected region preprocess should be generated.|
This parameter enables optional attributes to be passed in to control aspects of the preprocess generation, if special behaviour is desired.
(There are currently no attributes for connected regions preprocess, this argument is included for future compatibility reasons.)
If no special behaviour is desired then you can just pass zero in for this parameter, to indicate no attributes.
Unobstructed space must be present for the shape on this mesh, and must be 'combined' (i.e. the 'combine' argument should have been set to true when generating unobstructed space).
Connected region preprocess must not already be present for the shape on this mesh.
You can avoid the overhead of generating preprocess at runtime by using
Multithreading details: Base mesh preprocess generation operations are non-blocking between shapes,
so preprocess can be generated for multiple shapes simultaneously.
void generateConnectedRegionPreprocessFor(Shape shape, string options);
