  WebGL renderer
Posted by: Nicola - 2012-11-16, 14:58 - Forum: LDraw Editors and Viewers - Replies (150)

Hello! I'm playing with LDraw a lot lately, and i decided to implement something to display models with WebGL.
Here's the experimental results and some more information:

http://www.lugato.net/ldraw/page.html
new url: http://www.lugato.net/brigl/index.html

I think a WebGL renderer would be great to show off models on the web. No plugin, no downloads, etc.
It's very crude but it already show some models

Ideas and feedbacks are welcome Smile

  LSynth "Add Command ..." Selection Greyed Out
Posted by: rwjorgen - 2012-11-15, 17:12 - Forum: LDraw Editors and Viewers - Replies (3)

OK, I think I followed all the instructions for integrating LSynth with MLCAD; however, when I attempt to use the Extras -> LSynth -> Add Command ... menu item, the menu item is greyed out and will not let me select. So, I must have something wrong in my configuration settings.

I have the LSynth parts listed on the MLCAD part windows on the left panes. I followed all the instructions as written for integration and updating the MLCAD.ini file. (see attached)

  SteerCo Announcement: LDraw attribution and a minor change to Policies and Procedures
Posted by: Tim Gould - 2012-11-14, 20:51 - Forum: LDraw.org Announcements - No Replies

We have now added a page with code snippets to make LDraw attribution easy for software developers and websites, as required by the license for software or sites that offer the LDraw Parts Library. This is not the only way to attribute LDraw, but allows for a standardised attribution.

http://www.ldraw.org/the-ldraw-organizat...ldraw.html

To reflect this we have also made a minor change to the LDraw.org Policies and Procedures (sec 2.05) by adding a parenthetical mention. Thus

Quote:We would appreciate that the LDraw logo, as well as a link to the website are included and possibly featured prominently.
has been changed to
Quote:We would appreciate that the LDraw logo, as well as a link to the website are included and possibly featured prominently (for an example of how this can be done please see the "Link to LDraw" page on the LDraw website).

  New to Lpub and sub models not loading
Posted by: Miguel Valenzuela - 2012-11-14, 7:33 - Forum: LDraw File Processing and Conversion - Replies (12)

HI Everyone, this is my first post on this forum.
I am new to Lpub and am trying to figure out how all this works.
I have made a model in MLCAD 3 and am using an older version of LPUB and POVRay and running windows XP.
First of all, can you recommend places to download the latest version of Lpub that is simple to get to?
I feel it's hard to find what the latest version is and also to get it to work.
Second, I first had problems with the parts list. Lpub would return an error saying it couldn't find the sub model so I added the name of the sub model to the parts list to get around this.
So I got it to render the initial parts but it hangs up when it gets to the first sub model and can't find it.
I know there was a recent post about this but I didn't get a clear answer on what I should do.
Any help is appreciated.
Thanks
Miguel
Oh, and last, what is the easiest way to publish instructions, is there another program instead of Lpub?

Posted by: Roland Melkert - 2012-11-13, 20:30 - Forum: Part Requests - Replies (10)

  New Lead Theme "How To"
Posted by: Michael Heidemann - 2012-11-13, 19:08 - Forum: Website Suggestions/Requests/Discussion - Replies (1)

I would like to see a new lead theme where everybody can send his How to's to.

Here an example:

The first line should be the subject/headline:

How to fix a portion of wrong winding in a file with DATHeader

If you have for example a file where at some point the winding is changed:

Go to the Editor Tab. Mark the lines between both BFC statements. Click the right mouse button and choose from the context menu „Reverse Winding“.

You will got the following code:

  view diff is broken?
Posted by: Matthew W. Noel - 2012-11-12, 23:00 - Forum: Help - Replies (14)

On the parts tracker whenever I click on "view diff" my browser (Google Chrome) downloads a file called "ptdatdiff.cgi" which i can't open. I know chrome is compatible with .CGIs because it had to use ptdetail.cgi to get to the "view diff" link. Anybody know why this might be happening?

  Time stamping messages?

Could it be possible to get absolute time stamp on messages in addition to relative time stamp ("2 days ago")? It would be easier to use to reference things (eg. "when was this version of xxx program published?")

  Bricksmith 2.6.1: Texture your world (now with more standards compliance!)
Posted by: Allen Smith - 2012-11-12, 5:38 - Forum: LDraw Editors and Viewers - No Replies

[Image: icon32.png]

Bricksmith 2.6.1 adds the following features:

  • Automatically checks for and installs application updates

It also fixes the following bugs:
  • Fixed texture search path (now correctly searches ldraw/parts/textures)
  • Fixed issues with drag handles inside textures
  • Fixed object selection inside textures

Hot on the heels of a whole raft of new features in Bricksmith 2.6, this bugfix release corrects several errors with the original TEXMAP implementation. Furthermore, the oft-requested update feature will also help you snag future improvements without watching this message board obsessively.

Bricksmith requires Mac OS X 10.6 or later, and may be download it at <http://bricksmith.sourceforge.net/>.

Sincerely,
Allen Smith

  solving the remaining problems for Electric Plugs on the Parts Tracker
Posted by: Steffen - 2012-11-11, 14:13 - Forum: Parts Authoring - No Replies

The electric plugs of the 4.5V and 12V era are nearly 99% completed.
They currently all sit on the Parts Tracker:
http://www.ldraw.org/cgi-bin/ptreviewsum...ctricplugs
However, there are a small handful of problems to be solved,
and I would like to ask for help, advice and/or a caliper in this case,
as I am not at my LEGO collection currently (sadly).

PROBLEM A: Plugs Intersect with Parts in Assemblies
Here's an example:

Code:
1 16 0 0 0 1 0 0 0 1 0 0 0 1 4169.dat
1 0 0 -122 -1 0 0 -1 1 0 0 0 -1 0 512p01.dat
1 0 0 -122 23 1 0 0 0 0 1 0 -1 0 266bc02.dat
1 16 0 -102 10.5 1 0 0 0 0 1 0 -1 0 766ac02.dat
What you can see here is that the plug intersects with the signal main body.
There are 2 possible reasons for this:
(i) the plug is too thick
(ii) the sockets in the 2x2 lightbrick are misplaced
How should we solve this?

Problem B: Vertical Sockets Placement in Lightbricks
When you look at the 2x2 lightbricks in this example, you can see that the vertical placement
of the electrical sockets is different at the white 12V brick than at all others.
As far as I remember from my childhood, this was not the case.

1 47 223 12 0 1 0 0 0 1 0 0 0 1 933c02.dat

Problem C: Diameter of Foil Plugs
The diameter problem of the foil plug
http://www.ldraw.org/cgi-bin/ptdetail.cg.../u9238.dat
is still unsolved. Choosing a radius for it which would make it fit snugly into its plastic parent
would make it no longer fit into existing socket holes.
Choosing a radius such that the latter works would no longer make it fit into its plastic parent.
