Packing Blocks + 方體填充進階版

跟上一代方體填充的差別是,
只要你的塊體是由某一最小單元組成,
它都可以將其填充到範圍內,
當然範圍也應是由同一最小單元組成.

Different from packing blocks,
as long as the blocks are constructed with a minimal module, 
it can pack it into the boundary,
of course the boundary should be constructed with minimal module too.

範圍不一定要是方體,
當然也能有中空的範圍.

The boundary doesn't have to be a rectangle,
and of course it can has hollow holes in the boundary too.

你可以選擇只要用輸入的方體填充,
亦或是方體的四向度旋轉也納入填充選擇內.

You can choose to only use the input blocks for packing,
or each block's four dimension rotation can be consider for packing as well.
