So - we saw handy do these in his mini_arena
and then explaining their creation in a tutorial included in factory..
also SheeEttin gave a very quick how-to in his comment to the mini_arena-node.
I've decided to put this up as a real guide too though - credits do have to go to those two for the research though! Well done boys - that's the true spirit of this community!!
|1||First we need a regular cube.
We use the default gridsize (3) for our tutorial.
|2||Now we push one corner in all the way (left pic),
then back one step (right pic).
This tutorial has picked the bottom-left,
so for each face that's the corner to point to!
Use Q+MW to push/pull corners.
|3||Repeat this operation for all four side-faces of the cube.
On the right pic you can see clearly
how each edge has been pushed in exactly an 8th.
|4||Now go round again,
pushing in the last 8th.
The left pic is the before,
the right pic the after.
After corner #3 you'll see the bottom face disappear.
Hope that helps.
