  Phorum signatures

It seems that if I update my signature, all previous postings show the new signature. Is this dynamic behaviour configurable? I'd prefer the posting to contain a static copy of my signature at the time it was created.

  LDDP and MPD Wizard bug
Posted by: Orion Pobursky - 2011-11-27, 3:01 - Forum: Parts Authoring - No Replies

Note that spaces in filenames breaks all of my programs that are based on my DAT parsing toolset (which is all of them). This includes all versions of LDDP and MPD Wizard. This is fixable and I will be pushing updates. LDDP will take a bit since I'm in the middle of a major update of the code base.

  James Jessiman Memorial Award for 2011 awarded to Travis Cobbs
Posted by: Willy Tschager - 2011-11-26, 20:22 - Forum: LDraw.org Announcements - Replies (8)

The SteerCo is pleased to announce that the 2011 James Jessiman Memorial Award (JJMA) recipient is Travis Cobbs.

Travis Cobbs is the author of LDView, one of the cornerstones of the LDraw System of Tools. When it comes down to quickly viewing a LDraw file, LDView is the first choice for many users. Additionally, do to his active development since it's release in 2000, LDView has become the de facto reference renderer for LDraw part and is used by the LDraw Parts Tracker to generate part images. Travis has been a major player in shaping almost all the LDraw standards and specifications and has furthered the LDraw language and community as member of the LDraw Standards Committee since 2006.

More information on the JJMA can be found at:

  Use of "LDraw" in the name of ldraw related programs.
Posted by: Jean-Philippe Ouellet - 2011-11-26, 8:07 - Forum: All Other Programs. - Replies (6)

SteerCo has since voted not to allow this. See this announcement.



The day is slowly approaching when I will make my WebGL based LDraw software public.

Right now, I call it "WebGLDraw". I believe it is a clever name as it is almost a direct concatenation of the two technologies that compose it, however, I remember from reading Bricksmith years ago that internally, it calls itself MacLDraw. I believe (it's been a very long time) that I remember reading in some comment someplace in Bricksmith something about that it was going to be called MacLDraw but that the name was changed because the community had reservations about using the name LDraw... something about people possibly inferring that it was an official mac version of LDraw written by James or something... not sure. I tried to go back and find the explanation, but I was unable to, so I ask you here.

Is it ok for me to you the name WebGLDraw? Or should I name it something else? Do you have any suggestions for a name?



Also, as for Logos, is this acceptable?

(BTW, I wrote it as an SVG, I just can't attach them here)

It was designed to look like:

Which was in turn designed to look like:

  Automatic matrix corrections
Posted by: Roland Melkert - 2011-11-25, 19:02 - Forum: Parts Authoring - Replies (6)

Hello all,

I discovered rendering glitches in the Linux version of my LDCad are caused by the limited way I correct 'invalid' matrices in part files. The wrong matrices cause all kinds of lighting problems in Ubuntu 11.10 with the open source radeon driver. Yet for some reason the windows driver couldn't care less, how's that even possible?

Anyhow I'm improving the correction code, but not being a part editor or a matrix expert I'm having difficulties with it. For example I can correct these (log fragment):

Code:
parts\2694.dat | line 164 | Matrix corrected from [10 0 0 0 0 0 0 0 10 ] to [10 0 0 0 1 0 0 0 10 ]
parts\2694.dat | line 165 | Matrix corrected from [-10 0 0 0 0 0 0 0 -10 ] to [-10 0 0 0 1 0 0 0 -10 ]
parts\2695.dat | line 13 | Matrix corrected from [6 0 0 0 0 6 0 0 0 ] to [6 0 0 0 0 6 0 1 0 ]
parts\2695.dat | line 14 | Matrix corrected from [6 0 0 0 0 6 0 0 0 ] to [6 0 0 0 0 6 0 1 0 ]

These all have exactly one row that's all zero's, the position for an automatic '1' can be determined quite easily.

But what about these:

Code:
parts\3039p32.dat | line 40 | Invalid matrix detected [2 0 0 0 0 1.4286 0 0 -1.4286]. It could not be corrected automatically, it might cause rendering glitches.
parts\3039p32.dat | line 41 | Invalid matrix detected [2 0 0 0 0 1.4286 0 0 -1.4286]. It could not be corrected automatically, it might cause rendering glitches.

I'm guessing the middle '1.4...' should move one place to the left, but how to automatically detect and correct for this (you could also do this for the 3rd row not?).

And these are even worse I think:

Code:
parts\6016.dat | line 38 | Invalid matrix detected [2.84 0 2.84 0 0 0 2.84 0 -2.84]. It could not be corrected automatically, it might cause rendering glitches.
parts\6016.dat | line 47 | Invalid matrix detected [-2.84 0 -2.84 0 0 0 2.84 0 -2.84]. It could not be corrected automatically, it might cause rendering glitches.

Or could I just put a '1' in the middle row's middle pos?, but yet again how to do a fool proof correction.

Any help would be appreciated.


Or maybe someone could just fix all the part files (just kidding Big Grin)

  Patterned parts numbers
Posted by: Damien Roux - 2011-11-24, 22:56 - Forum: Parts Authoring - Replies (6)

Hi all !

As I'm continuing to (slowly) make patterns using Stan's SVG files, a question came to my mind.

For 973 Star Wars patterns we reached 973psz. So what's next ? 973psa1, 973psa2, ... ???

  3433 Tractor Chassis Excavator Bucket, Large
Posted by: Christoph Mierowski - 2011-11-24, 15:58 - Forum: Parts Authoring - Replies (1)

This part is already existing- my question is if there where two version of this part?
http://www.bricklink.com/catalogItem.asp?P=3433

In an old 70s set there is this part combined with 828 Tractor Chassis Excavator Arm, Large (828.DAT) and all fit fine with the Ldraw parts.
http://www.bricklink.com/catalogItemInv.asp?S=378-1

But this part was also combined with 3314 Excavator Arm 2 x 6 x 2 (e.g. see:http://www.bricklink.com/catalogItemInv.asp?S=6630-1) and there 3433.DAT and 3314.DAT have a missfit. To be more precise the connection seems to have a to small radius.

The best is somebody would take a close look on both combination.
Has somebody all of these parts I'm talking about? - The real thin could solve the problem....

  LDConfig Confusion
Posted by: Tore Eriksson - 2011-11-24, 1:18 - Forum: Parts Authoring - Replies (22)

I just downloaded the latest LDConfig.ldr from http://www.ldraw.org/library/official/LDConfig.ldr
Its header reads:
0 !LDRAW_ORG Configuration UPDATE 2011-06-03

But I already have a copy of LDConfig.ldr, and its header reads:
0 !LDRAW_ORG Configuration UPDATE 2010-06-19

This is supposed to be newer, but in the currently official but older(?), there are four more colours compared to the one I already have on my hard drive.

83 Metallic_Black VALUE #1A2831 EDGE #000000 METAL
87 Metallic_Dark_Gray VALUE #6D6E5C EDGE #5D5B53 METAL
321 Dark_Azure VALUE #078BC9 EDGE #088DCD
323 Light_Aqua VALUE #ADC3C0 EDGE #AFC9C2

What is this file dated 2011-06-19? I don't know where it comes from.
And are those four colours official standard? (I guess so since they are there in the ufficial version.)

/Tore
