BrickCon 2008 Early Registration is now available at
http://www.brickcon.org/register-yourself
at the special Early Registration price (prices go up starting in August).
BrickCon is an annual adult Lego hobbyist convention and exposition in
Seattle.
BrickCon 2008 will be October 3, 4, and 5, with load-in and some events
starting Thursday, October 2.
The venue this year is the Exhibition Hall at Seattle Center
http://www.seattlecenter.com/booking/detail.asp?VE_VenueNum=510
which is in the same general facility as recent years (Seattle Center) but
much larger and has adjoined, dedicated classrooms and other nifty
features.
The schedule of events for BrickCon 2008 has not been finalized but
currently includes reduced public exposition hours (11am--3pm Saturday and
Sunday) and many of our traditional events (a draft, a Dirty Brickster,
speed builds, a blind build, etc., etc.).

I was asked the following question:
David,
I just caught your article on LUGNET about usingPov-Ray, I tried the code you
had posted with a .ply Ihad and it didn't work, gave me errors on the textureand
translate lines, is there any chance you couldsend me your .pov file version of
the Stanford Bunnyfor me to look over?
I, like you, would like to design lego "sculptures"using the abundant software
available and buildaccordingly.
Any help would be great!
Thanks
-Josh
In response I have posted the pov file generated from the ascii version
(bun_zipper.ply) of the bunny as posted from the The Stanford 3D Scanning
Repository. The coordinates and the triangle indicies should be unchanged from
that ascii file, so the mapping from the ply to the pov file should be pretty
clear.
http://www.brickshelf.com/gallery/happyfrosh/StanfordBunny/bunny.pov
To deal with the holes in the original ply mesh model I consider the mesh object
to be the intersection of several different mesh objects, each with a different
outside vector.
The command lines that I use to run povray are in a "#if 0" block at the bottom
of the file.
To get color I render the same model from six directions, then use a voting
scheme to decide what color a voxel is. I use the alpha channel of the png to
better determine whether a particular voxel is filled or not.
The attached model uses for the interior
color rgb <0,0,1>
and for the exterior
color rgb <1,0,0>
Note that the exterior will be visibile in only a small minority of the pixels,
but with voting and masking out the known interior color, this is enough. The
red color can be replaced with an actual pov texture or such. (I did one
leopard spotted bunny this way)
This pov file also includes some 2.5d work that I was doing. Terrain map like
stuff. Activated by setting the clock to 0 and declaring "DEPTHMAP".
The standard bottom-to-top rendering as described in the paper is the command
line with "Declare=CAMERAPOS=2".

TOTALLY AWSOME. Maybe using some black 1x2s in the eyes (nose and mouth) would
give it some better definition.

Hey Todd,
Abso-freakin'-lutely awesome!! Now it just needs some flashing rend lights in
the eye sockets and you're ready to throw down some serious Lego voodoo!

Hi guys,
I'm looking at options for setting up a content management system for the
Brickvention website (it's currently static HTML). I've tried Geeklog on another
site, and it's OK, but doesn't do everything I'd like to do for our site. I was
checking out your site, and I like how it's setup, I was just wondering what
software you're using?
Thanks

That looks beautiful! Will you be bringing it to NWBC? I’d love to see it in
person!

I was planning on taking it to NWBC but it won’t be done in time for this year.
Maybe next time. Waiting for more pieces to arrive, I do plan on getting it
finished in a month or so.

After almost of two years of work on and off, my 7 1/2 foot tall Seattle
Space Needle is almost complete. I have been wanting to post my progress for
a long time, but moving and buying a house has put me back on finishing the
space needle and posting pictures. So it is not quite complete but will
update my MOCpage and post more pictures to brickshelf. When it is finally
complete I will give an update here and better pictures of this project.

Now that’s just beautiful! I love the seamless blend of building techniques and
the slickness of the final model, the inhabited areas and supports also look
good together (a failing of many MOCs). Very good work indeed.
Thanks for sharing and God Bless,
Nathan

Hmmm, not sure how I missed this post... but thats a totally awesome sculpture.
I just got done adding your skull to my

I said there, I especially love the jaw line, teeth and the accoutrements,
particularly the little man talisman.

Very nice work! This is my faviourite sculpture in ages! The whole thing is
so realistic and beautiful it was a pleasure to look at. Now I am picturing a
cave inside similar to Peter Pan...
God Bless and thanks for sharing!

Will probably finish this over the weekend with the last detail elements just
needing to be located...may think about moving the nose cavity down a few
plates to locate more accurately, depends on structure.
Notes: Life sized, hinged jaw to allow some movement or “talkin”.
(Hmm...might need to add that.) All parts but the bandana will be LEGO
elements, including string to attach.
Folder after moderation

Shoot,
Finally finished the details. Also filled in the head to hide some of the “see
through” aspect of the model. Enjoy! T

Yes, once again it is time for the Dirty Brickster at NWBrickCon. Yes, it is
once again time to peruse your various Lego and Lego related stuff to find that
perfect gift to exchange, that thing you don't really need but that someone else
may go ga-ga over, or possibly agree that it sucks, or maybe if they are lucky
will at least be able to trade it for something good at Wal-Mart.
So bring your gift, valued in the $10 to $20 range to NWBrickCon for the Dirty
Brickster. Make sure it is wrapped. We will draw numbers and you can choose a
mystery item or be a Dirty Brickster and steal someone else's treasure! Only 3
steels allowed per item (with the possible exception of the first person - we
will vote on that before the event).
This is always great. And I promise this year I'll be bringing something a lot
better than Mushroom Bins (although of course, these excellent sorting and
storing bins will once again be available for you to test and purchase!)
It isn't too late to register for the best Brick show in the Northwest.
Register now at www.nwbrickcon.org, and we will see you October 7th-9th!
-Matt :)
Dirty Brickster Coordinator at NWBrickCon
And also the Brick Bazaar Coordinator, so be sure to let me know if you want to
sell stuff!

This is somewhat of a repeat, but the deadline for pre-registration is fast
approaching... Bring your Lego wares to NWBrickCon!
NWBrickCon will be held October 7th-9th at the Seattle Center. And the Brick
Bazaar is a fanstastic time to unload your surplus Lego or move some product
from your retail inventory. If you want a full or half table reserved for you,
please let me know as soon as you can. There is no table fee, but a donation
for the door prize would always be appreciated!
The public will be in for a while on Sunday to the Rainier Room (not the Brick
Bazaar room). If you want to sell your wares to the public (not just conference
attendees) it is an option. However it will require you to get a City of
Seattle Business Liscense (cost of around $45 I believe). If you are getting
the liscense and want a table(s) during the public time, let me know and we will
work out the details.
If you just have a few sets to sell (not parts) there is a local toy dealer
(Math 'n Stuff) who will be there, and they have agreed to act as agent and sell
to the public for you! You will need to keep an eye on your own merchandise
during the public time if you do that. It is a great, EASY way to sell custom
sets or older retired sets.
Remember, to sell to conference attendees during the regular Brick Bazaar is a
no-fee and no-liscense needed thing! So just send me an email at
mattchiles@gorge.net to sign up and reserve your space.
Oh yeah, we will provide tables and skirting. You bring stuff to sell, shelving
if needed, bags if appropriate, change box & small change, business cards, table
cover sheet for while you are gone, signs and price tags, some paper and pens
for notes you may need to take, and all that sort of stuff. Don't plan on
electricity being available at your table, although we will do our best to
accomodate if needed (bring your own extension cord and we will see what we can
do). And DON'T FORGET TO REGISTER FOR THE CONVENTION NOW at www.nwbrickcon.org!

I'm in charge of the Brick Bazaar at NWBrickCon again this year, and it is
comming up fast! This year NWBrickCon will be held October 7th-9th at the
Seattle Center. The Brick Bazaar will be a much better location this year (the
Olympic Room) than last year.
The Brick Bazaar is a fanstastic time to unload your surplus Lego or move some
product from your retail inventory. If you want a full or half table reserved
for you, please let me know as soon as you can. We don't even have a table fee,
but we would request you donate something to the door prizes if you can.

I know that everybody has done a sphere... I’ve seen a sphere calculator (very
very cool, not studs-up, and instructions somewhat hard to follow). I thought
that I would be thorough...
So here are plans for studs-up sphere sculptures of radius 2 through radius 48.
jpg and ldr of each of these.
The 40x40 sphere turns into a nice moonbase.

I was asked the following question:
Wow! How did you digitize the mesh into Lego units? Did you do a "hit
test"
on each vertext/face within lego units, or perhaps do a boolean subtract
out of a composite lego 'block'? Inquiring minds want to know! ;)
---Will
In response:
I used povray and rendered slices through the bunny.
For this to work the section
vertex_vectors {
35947,
<0.0378297, 0.12794, 0.00447467>,
...
<0.0400442, 0.15362, -0.00816685>
}
face_indices {
69451,
<21216, 21215, 20399>,
...
<17277, 17346, 17345>
}
Needs to be replaced with the actual vertex_vectors and face_indices of the
bunny. It's a fairly simple transformation from the ply file format available
on the Stanford web site to this format. Note that this technique will work
with any POV CSG object.
Render this as an animation for clock=frame=1 to clock=frame=25
Then shrink the images of the animation to 32x32 pixels. (matching up with the
LegoWidth declaration below) (LegoHeight could be replaced with 0.4 for plates).
Each frame of the animation is a Lego layer.
Place a lego block there if each pixel of each layer frame is more white than
black. (An easy way to do this is to use a graphics program to transform the
file to a text pbm format, which uses "1" and "0" for the two allowed colors
(black and white))
Begin pov code:
#version 3.5;
#include "colors.inc"
#include "math.inc"
global_settings {
ambient_light rgb<1, 1, 1>
assumed_gamma 1.0
}
#declare LegoWidth=32; // in studs
#declare LegoHeight=1.2;
#declare SceneWidth=0.1712689; // about the width of the mesh object // scene
will require 25 frames for LegoWidth of 32.
// scene will require 37 frames for LegoWidth of 48.
#declare orthoLookAt=<0, 0, 0>;
camera {
orthographic
location orthoLookAt+y*100
look_at orthoLookAt
right SceneWidth*x // horizontal size of view
up (SceneWidth*image_height/image_width)*y // vertical size of
view
}
// ----------------------------------------
// CSG intersection, the common space where all the shapes meet intersection
{
#if (clock>=1)
box{<-1,-LegoHeight*(SceneWidth/LegoWidth),-1>,<1,0,1> translate
y*(0.0329874+clock*LegoHeight*(SceneWidth/LegoWidth))}
#end
mesh2 {
vertex_vectors {
