i am trying to recreate a castle wall macro. instead of the usual layered
bricks im going for a more random approach. this is the result so far. i
know there is a kind of order to the randomness but i am working on it.
any suggestions/comments.
cheers,
John Robinson

I don't if I could help with the randomness problem but I do have 2
suggestions:
1. It looks like one big slab with fake brick lines etched into it instead
of lots of bricks from the same slab because the bumps on the bricks line up
2. Some of the bricks are way too thin. You need to specify a minimun width
and height

it does kind of look that way but each brick is its own isosurface. a
better pigment map is needed i think.

youre right and im already on the case.

The pattern needs some work, as you have said. There is at least one macro
around that builds a wall like this, but I do not know where it is or how it
works. It should be simple enough to adjust your algorithm to make a more
random wall.
One interesting way to accomplish this would be to build a macro which
generates Tetris style shapes made from random blocks. The shapes could then
be arranged into a solid wall. I'm sure that this is overly complicated and
inefficient, but I'm curious how well the pattern would be hidden.

There have been a few of these types of macros made in the past, have a
look at the scen files groups. I remember Gail Shaw making one and there
have been others too.

heres the second attempt. i rewrote my macro but the symmetry is there if
you look closely.

Wow, the walls look really great, but the sphere swept edges are sort of
odd. Maybe if you cut the radius way down on the inner one and removed it
altogether on the outside edges, it would look better. I can imagine some
mortar inside that inner joint, but the outer edges of stone walls were not
dressed that way. It looks like caulking squirted on the edges.
The incising is great and the overall feel is too. This looks like it would
be a fun macro to play with.
Cheers!

you mention sphere swept edges. do you mean along the rims of the doorways?
they are actually isosurfaces (half torus and cylinders) but they do look a
bit too much like cake icing :)
