Hi folks,

Once more we are rather late with the nominations/election process...

The LDraw.org Standards Committee (LSC) is responsible for maintaining semi-regular internal discussions on pending file format issues, the overall progress of the LDraw file format and new or proposed developments made by different LDraw-based software authors. They adopt new official standards by voting on them, and publish documentation on LDraw.org following such a decision. The LSC has documented and will document past, current and future LDraw File Formats.

With revision 1.5 of the LSC Charter the number of seats is restricted to 4 since one seat is reserved for a current LDraw Library Administrator.

To be eligible for LSC membership, per the LSC Charter you must fulfil at least one of the following:

* Authored at least two LDraw parts subsequently released in an Official LDraw.org Parts Update
* Served as a reviewer on the Parts Tracker through at least 2 official parts updates, and posted at least 5 reviews in at least two updates since their initial participation
* Authored a software program that is compliant with either the LDraw 1.0.2 specs or another spec published by the LSC
* Petition for nomination as an LSC candidate approved by 2 current LSC members
* Petition for nomination as an LSC candidate made to the LSC by at least 5 others eligible to be LSC candidates

People can either self-nominate or nominate someone else. When nominating, please reference the person’s eligibility from the list above. For the LSC there is non need that another member of the community seconds the nomination.

Nominations MUST be posted in direct reply to this post to be counted, and must be online by 12:00 PM GMT February 14.

Voting for the elections will begin February 15, and end March 15. The LSC will officially change over on April 2nd, giving time to transition newly elected members into the committee.

Only LDraw organization members are permitted to vote in this poll. Since we have yet to implement a new membership system, we consider you a member if you have signed up for the forums and have an active account with a real name attached

Per the LDraw.org Bylaws at http://www.ldraw.org/article/268.html, Subsection
6.03(a), the 2013/2014 Steering Committee hereby calls for the community to
nominate individuals as candidates for the 2014/2015 Steering Committee[1].

Please post nominations in response to this message. Nominations will only be
recognized if they are in response to this message.

Only LDraw organization members are permitted to nominated or vote. Since we have
yet to implement a new membership system, we consider you a member if you have
signed up for the forums and have an active account with a real name attached

Per ss.6.03(a), you must specify the name of the person you are nominating,
along with your name. Another member of the community must second the nomination
in a reply, and the nominee must publicly accept the nomination in the same
channel (direct reply to the nomination or second) in order to be valid. If the
nominee does not accept, it will be assumed that he or she has declined, and
they will not be placed on the ballot.

Nominations will close at 11:59 PM GMT on 28 February 2013. This means that to
be listed on the ballot, a candidate must have been nominated, seconded and must
have formally stated acceptance by that time.

The Steering Committee will give sufficient notice of the election and election
procedures per ss.6.03(b).

NOTE: subsection 6.03(b) states that elections should take place before March 1.
We interpret this to mean that we will commence the election on March 1, but
since it is electronic, it will run for 2 weeks, just as last time. The exact
time and date of start and end will be announced sometime very close to (but
after) 0000 GMT March 1.

Again, thanks to all of you for your commitment to the goals of the
organization, and in working with us this year. Please, stay involved with
LDraw.org and keep it moving forward!

Could we please increase the number of digits in the reference matrices inside parts?

I was investigating very weird behavior of my part snapping code and it turns out it's caused by inexact rotation matrices derived from primitive references.

It concerned the 120 deg angles connecters (10288 and 57585)

Replacing the rotation matrix with
0.5 0.8660254037844 0 0 0 1 0.8660254037844 -0.5 0

fixed everything, so please don't spare those digits when referring stuff at angles.

Just venting

I've created a wiki page showing the difference between renders done in POV-Ray 3.62 versus POV-Ray 3.7, and created using LDView versus L3P.exe. You can find it here:

https://code.google.com/p/datsville/wiki/TestRenders

The lighting is the same in all twelve renders; and a change in lighting might be better suited to some renders than others.

Hi all,

Does anyone has the exact spring specifications for the common shocks and pneumatic pump parts?

I want to supply default templates for them in the up comming LDCad version.

I'm looking for the wire thickness and winding counts (per spacing group). It doesn't matter if they are in rest or compressed state.

I need this for the following parts:

6.5L technic sock (both versions)
9.5L technic (bike) shock
10L technic damped shock

technic pneumatic pump 2 x 2 x 5 with large knob
technic pneumatic pump 2 x 2 x 5 with 1 port

Any help is appreciated.

Quote:Hi,

I am aware that this message should probably go to a different address, but it seemed the easiest to find.

You may be interested in inspecting two pages I just produced:

http://www.cailliau.org/Alphabetical/L/L...derations/

and

http://www.cailliau.org/Alphabetical/L/L...imensions/

especially the bottom part of the second page as it refers to LDraw.
I hope it sounds more positive than critical.

There are also pages on Duplo
http://www.cailliau.org/Alphabetical/L/Lego/Duplo/
but they are not connected to this subject.

Best regards,

What is the new name for part 6099p45.DAT? Also, how do I look up this information myself for when I run into this problem again? Thanks.

Hi Y'all,

I was dusting off my notes on LOD when I noticed that octa-studs have already been moved to /8 in the official library, something that was discussed here.

http://forums.ldraw.org/showthread.php?t...45#pid9745

This gives us three levels of detail by searching /p/8 and /p/48 for primitives.

I would like to propose a fourth level of detail, designed to be the lowest quality rendering possible. Such rendering would have:
- No studs at all.
- No part interiors.

The LOD would be targeted for real-time viewing of stupidly-huge models, e.g. all of Datsville at once, etc. The goal is to preserve some vague shape and color of the model while bringing down vertex count as much as possible.

The goal would _not_ be to replace every single part with a simpler version, but rather to replace a subset of parts that are very commonly used (e.g. all of the standard dimension bricks, plates, etc.), possibly using a human-directed script.

In my past experimenting with this technique I found that a small number of 'draft' quality bricks could have a pretty huge impact on the weight of a model.

Anyway, if anyone thinks this is a terrible idea, or has strong feelings on how such a sub-set should be built, please let me know. I'd like to start putting a part set together.

Cheers
Ben

Hej,
I'm proud to present: ToriCalc 1.0

You can calculate inner and outer tori and tubes. It's also possible to calculate the y-scaling for this torus.

If you find any bugs, please let me know.
As everytime - please remove the .dat to get the programme work.
