clump.pebble.inbox

Syntax

a = clump.pebble.inbox(vl,vu<,b>)

Get clump pebbles with extents intersecting a box. The extent is the axis-aligned bounding box of the pebble. Specifying b = false indicates that only pebbles with positions falling in the box are returned.

Note

• This function uses cell-space-based algorithms for efficient spatial searching, and therefore assumes that the clump pebbles are properly mapped into the cell space. Directly after the model has been restored, after clumps have been created or pebbles added to existing clumps, one must execute a model clean command prior to using this function.

Returns:

a - array of pebbles

Arguments:

vl - lower corner of the box

vu - upper corner of the box

b - optional intersection specifier
