  An unknown color ID referred by some official parts
Posted by: Mario Pascucci - 2014-08-19, 15:06 - Forum: Parts Authoring - Replies (4)

Hi all.

This is my first message, and I apologize in advance if this isn't the right section.

I'm experimenting on rendering LDraw parts and models in Java, and in an LDR model I found a part in latest official part library (2014-01) that use this color id: 391.
I can't find it in LDConfig.ldr, and I haven't found any reference to this color code.
So, part uses this color:
973psk.dat (for sub-part s/973pskb.dat) in row 19
I found a sub-part that uses this color, too:
s/3068s101.dat in rows 39, 51, 52


Thank you for your work on LDraw part library.

Mario

  PrimGen2 - new version
Posted by: Michael Heidemann - 2014-08-16, 15:18 - Forum: Parts Author Tools - Replies (1)

Based on the current discussion in the forum I updated PrimGen2.

I made already some tests, but as you surely know some bugs like to stay until they are discovered.

So please report any issue as answer to this post and I keep PrimGen2 alive and running.

You can download the current version at http://ldraw.heidemann.org/index.php?page=primgen2

  Skewing in official parts
Posted by: Roland Melkert - 2014-08-14, 19:48 - Forum: Parts Authoring - Replies (6)

As a result of this thread, I'm wondering are there any parts in the library using skewing (of base scaled reference), is it even legal?

I need to know to decide if it's worth the needed rewrites to my texmap meta implementation.

  Minifig guide?
Posted by: Michael Horvath - 2014-08-14, 12:02 - Forum: General LDraw.org Discussion - Replies (9)

Does anyone have a guide of minifig parts with pictures and part names? MLCad's part preview is a bit small and grainy. Thanks!

  Zombies?
Posted by: Michael Horvath - 2014-08-13, 12:32 - Forum: Part Requests - Replies (2)

Are there zombie minifigs made by TLG? There are some shown on the Web, but I don't know if they're official or not.

  Naming scheme for primitives - update
Posted by: Michael Heidemann - 2014-08-11, 17:15 - Forum: Parts Authoring - Replies (18)

It seems that there is a need for updating the naming scheme that Primgen2 uses for the primitives.
Here my suggestion:
x, y, z are values that will be substituted by primgen2 for the dimension of the part.
cylinder: x-ycyli.dat : always use cyli
disc: x-ydisc.dat : always use disc
ndisc: x-yndis.dat : always use ndis
chord: x-ychrd.dat : always use chrd
cone: x-yconz.dat : always use con
ring:x-yringz.dat : always use ring
circle: x-yedge.dat : always use edge

The length of the filename is not important anymore because I think we will not reach 25 characters.

If this should be common used, I am going to change Primgen2 quickly.

  Lpub/Bricksmith - Changing Orientations in Steps
Posted by: Mark Anderson - 2014-08-10, 16:57 - Forum: General LDraw.org Discussion - Replies (1)

I need a little help creating a set of instructions for a MOC I'm working on.

I'm using Bricksmith (3.0) on my Mac (10.9.4) and then bringing that into Lpub (4.0.0.10). I need to rotate the model in the instructions to show how to attach some pieces. Is there a way to do this in either Bricksmith or Lpub I'm not aware of?

Thanks!!

Mark

  TEXMAP extension thoughts and findings.
Posted by: Roland Melkert - 2014-08-07, 23:27 - Forum: Parts Authoring - Replies (33)

I've been working on the cylindrical implementation and I noticed some minor confusing things about the current TEXMAP spec.

The planar projection uses top/left orientation while the cylindrical one uses center bottom. This isn't a real big problem but the text states the v coordinate should be based on the distance to the base plane. This will cause the picture to be up side down.

So unless I misunderstood something (else) I think it should be the distance to the cylinder top plane.

Using that correction this:

Code:
0 Cyl texmap test minifig head
0 UNOFFICIAL PART
0 BFC CERTIFY CCW

1 16 0 0 0 1 0 0 0 1 0 0 0 1 s\3626bs02.dat

0 !TEXMAP FALLBACK
1 16 0 17 0  13 0 0  0 -13 0  0 0 -13  s\minifighead-hlp.dat
0 !TEXMAP END

will render like:

   

If people agree, we need to correct the spec text.



Second the spec doesn't mention what to do with over scan and or fully enclosed objects.

For example (using Nils' checker png Smile ).
Code:
0 !TEXMAP START CYLINDRICAL 0 0 0  0 -200 0   0 0 -200   180 checker.png
0 !: 1 15  0 -200 0  200 0 0  0 200 0  0 0 -200 4-4cyli.dat
0 !TEXMAP FALLBACK
1 15  0 -200 0  200 0 0  0 200 0  0 0 -200 4-4cyli.dat
0 !TEXMAP END

gives (over scan):
   

and
Code:
0 !TEXMAP START CYLINDRICAL 0 0 0  0 -200 0   0 0 -200   360 checker.png
0 !: 1 15  0 -200 0  200 0 0  0 200 0  0 0 -200 4-4cyli.dat
0 !TEXMAP FALLBACK
1 15  0 -200 0  200 0 0  0 200 0  0 0 -200 4-4cyli.dat
0 !TEXMAP END

gives (enclosed)
   

Both having the -180 == 180 problem

But again i'm not claiming my implementation is currently 100% correct.

Thoughts?
