New version 2.10 is up. Fences, gates, doors, trapdoors, and sign posts are now exported for printing when the "lesser" option is used; see more details here. Options for tailoring OBJ export, and improved documentation on exporting to renderers.
Alex Boden did some testing for me, showing that fences would print OK. On the left, 1 mm/block, the fences and thin pillars have sheared right off. 2 mm/block, in the middle, survived intact. With 3 mm/block, on the right, the
Version 2.11 is up for download. Added water and lava level export that matches Minecraft's; this always exports for rendering, and only when the "lesser" option is used for 3D print export. Support sideways logs and upside-down levers in 1.3.1. Bug fixes: flipped tiles on "lesser" objects so they properly matched left and right. Rewrite of the UV texture coordinate system in anticipation of major changes for full support of Minecraft 1.3.1 (modest reduction of number of UV coordinates saved). Mineways will mostly work with MC 1.3.1, but note that 1.3.1 texture packs used with Mineways will make chests disappear (thanks, Mojang). Major rework is needed to fix this mismatch; the default texture pack will work fine for everything but Emerald blocks.
TROLOLOLOLOL... Oh yeah. Anyway, I open the program, open a world, and all the exort options are faded, I cannot click on them. WHY????????? **sobs**
Right, you cannot export a whole world, you have to make a selection. Right-click on the map, hold your mouse down, and drag out a rectangle to export. That area is what you'll export. You can resize the window if you want a larger area, and can even drag outside this window, or just adjust the coordinates in the export dialog itself.
Other news, for all (since this forum software doesn't let me make a separate post):
Shapeways redesigned their website. It's better overall, but they changed their default units from meters to millimeters when uploading.
So, another update. Version 2.13: changed Mineways to export in millimeters by default, rewrote the documentation for Shapeways export.
Version 2.15 is out, with many additions. The focus is on new "true geometry" for 3d printing, along with the new blocks in the beta of 1.4. Here's the rundown:
Added "fatten lesser blocks" option, so that small features that are printed are less likely to snap off during manufacture. Removed "flatten blocks" option, since it's never turned off by anyone nowadays. Numerous minor tiled texture fixes. Fixed farmland output for printing. Added correct bed, cactus, and redstone repeater output for rendering and "lesser" 3D printing. Added sloped rails for 3D printing when "lesser" is on. Cauldrons with water levels added. Dragon egg geometry added. Command and beacon blocks added (default terrain.png only; beacon block is currently at 8,11), along with cobblestone walls, flower pots, carrots, potatoes, and wooden buttons.
I've had reports that the newer Mac version is having problems saving. If you have this problem, try out the (old, but workable) version 2.03, downloadable here. My next task is to work on this problem.
Here are two screenshots using the latest version, Minecraft on the top, G3D viewer (which gives the water a glow) on the bottom. The flower pots are quite cute up close.
I added a faked-up Ender Chest and fixed some bugs with display and color schemes.
bug fixes: fixed 3D printing color export for Sculpteo (OBJ) format viewed in SAP Viewer, fixed output of relative texture coordinates for OBJ export. Fixed color schemes so that old color schemes will autoupdate when used with newer worlds.Provided guidance to Mac users looking for their world directory (still trying to figure out how to make this happen automatically). Added Xzip/unzip in anticipation of someday reading texture packs directly for textures. Added Ender Chest, but only for default terrain.png. Thanks to Sterling Babcock for bug reports and the Ender Chest texture addition.
Here's a texture test, showing that almost all blocks now have true geometry:
Bug fixes: for cobblestone walls, pillars were not appearing on straight walls when objects were placed above the walls (thanks again to Sterling Babcock for the bug report). Also, in version 2.16 I tried to fix a problem for the Mac where it crashes for some users, possibly due to a memory use improvement introduced in version 2.09. I've turned this memory improvement back on in this version as it doesn't seem to matter for the crash. If you want to try out the 2.16 Mac version, download it here: http://realtimerendering.com/erich/minecraft/public/mineways/MinewaysMacV216.zip- if you have the crash problem and it helps you (or doesn't), let me know.
Water making cobblestone pillars appear. Before, note no pillars in the middle of the walls:
Version 2.18 is up. Mainly, I wanted to put in a bug fix for the "scale" feature, as it was wedged and is needed for the contest.
The whole release blurb: Output block size in statistics popup. Warn user if unknown block type is encountered. Add a "head block" placeholder (pumpkin) for now; it turns out to be hard to really add the new beta's head blocks. Bug fixes: fix the scale dialog (the radio boxes got separated from one another). Turn default options (connect blocks, delete floaters) back on when "lesser blocks" option is turned off. Attempt to find Minecraft worlds a bit better on the Mac (no promises...). Remove warning about floaters when "lesser blocks" is used.
In the meantime, for the Curse/Shapeways contest I made two pseudo-entries (the models aren't my work), to test the system. All entries to the contest are here (just my tests, so far). They're actually more fun to look at on Sculpteo, here and here.
I'm working on version 2.19 - mostly little texture fixes and subtle improvements - but this week I'm focusing on getting ready for the Mini Maker Faire in Somerville, Massachusetts, Saturday October 13th 3-7 pm. If by chance you live in that area, check it out. I'll be there demoing Mineways, with some (little) models on display. Really, you should go just to see Stompy's leg.
In the meantime, here's a cool print from Sterling Babcock; more photos here. I've ordered a new and improved version he's made since then, should get it by the Faire.
