Pirates and belt buckles |

I've started reworking the parts listed in this thread. They all use the old method of creating blended/dithered colour. Colours that are not present in ldconfig.ldr.
In that list are most of the old pirates. I have asked about them before
973p30.dat Minifig Torso with Pirate Purple Vest and Anchor Tattoo Pattern
973p31.dat Minifig Torso with Pirate Stripes Pattern (Red/Cream)
973p32.dat Minifig Torso with Pirate Stripes Pattern (Blue/Cream)
973p33.dat Minifig Torso with Pirate Stripes Pattern (Red/Black)
973p34.dat Minifig Torso with Open Jacket over Striped Vest Pattern
973p36.dat Minifig Torso with Pirate Captain Pattern
973p3b.dat Minifig Torso with Brown Vest, Ascot and Belt Pattern
973p3e.dat Minifig Torso with Pirate Stripes Pattern (Blue/White) discussed here
Is this all? Or, how many is missing?
How about the one with a black belt buckle?
The belt buckle should be changed to the obvious Metallic Gold (82), but how about the belt?
Many use the dithered code 486, but not all.
Do they all have the same shade of brown colour, but printed on different brick colour, hence looking different?
What is the best brown to use?
I used a rgb colour in 973p34.dat, A5832F created by ColourSum.
I now want to give them all the same colour and use the nearest one, as suggested by ColourSum, Fabuland Brown (450).
The striped pirates should use, as the description says, "cream". They use code 495, which in Electric Contact Copper. Must be changed.
We don't have anything close to "cream". The closest I can find is Light Flesh (78). Would that be OK?
Is code 450 (Fabuland Brown) OK as colour on the leather belts?
Is code 78 (Light Flesh) OK as colour on the 'cream' stripes?

Subfile References and Scaling |
Posted by: Nathan Friend - 2015-06-22, 23:48 - Forum: LDraw File Processing and Conversion

I'm writing an online LDraw viewer using three.js and am getting some strange results when I try and render subfile references.
Here's what I have currently - this should be a basic 2 x 4 brick: http://nathanfriend.io/ldraw-visualizer (Note that I'm randomizing the color of all surfaces so I can clearly see how each is being rendered.)
As you can see, all subfile references are being translated too much, especially along the X and Z axes.
Here's a pseudo-code representation of how I'm calculating the positions of subfile parts:
Code: subfileGeometry.applyMatrix(matrixFromSubfileReference * matrixThatRepresentsAllParentTransforms);
You can see the relevant portion of this calculation here.
Any ideas as to what I'm doing wrong?
My current theory is that some part in the subfile chain is being scaled (for example, '4-4edge.dat' is non-uniformly scaled by a factor of 6 inside of 'stud4.dat'), and the assumption is that this scaling should not be applied to its own subfile references. This scaling would then causes exaggerations in the position of all descendent subfiles. If this is correct, I'm not sure how to go about counteracting the scaling.
Any hints would be much appreciated.

SnapCAD is available! |

SnapCAD was released officially yesterday by VEX. This is a "new" LDraw editor that targets robot building using VEX IQ parts. It is an adapted version of MLCad, and uses the parts that I modeled from VEX 3D models.
See SnapCAD page here.
As a side note, SnapCAD can be used for regular LDraw stuff (your just have to change default library and categories). And it does correct a few MLCad known bugs, such as the greyed-out vector rotation (you must uncheck "absolute position" to make it available).

Attribution to LDraw.org in slides for public presentation |

Hi all.
I read this, this, this and this topic, but I didn't find a specific policy, and I don't want to make assumptions or to do analogies.
Briefly: in August I'll do a presentation of my software jBrickBuilder during AFOL event "Lecco 2015" in Italy. I wonder what is the right formula to say "this program is based on Ldraw Part Library". My thinking was:
- place this formula in first slide
- in second-last slide, where usually goes thanks and references to other materials/websites, thanks to LDraw people and a link to LDraw website with LDraw.org logo used for linking (as stated here)
- in last slide, a warning that jBrickBuilder is not endorsed or sponsored by LDraw.org or LEGO® company.
Is that right/meets LDraw policies?
My apologies in advance if question was already discussed, in that case can someone point me to topic/documents?
Mario

Animate building a model |

Hi all,
What would be the right tool (if there is one) to animate the actual building of a model?
I am looking for something of a mix between LDD where you see a new brick flying in to snap to the right position and the movies by ArtiFex Creation (https://www.youtube.com/user/artifexcreation/videos)
Would this be possible with some LDraw tools?
I'm thinking simple rendering an image of each step and then animate each frame using some moviemaker program.
But then, each image of each step has to be the same width and height and the model (base) should be in a fixed position. How do I do that?
Thanks again all.
Jaco

Find out what parts in LDD convert tot LDraw |

Hi all,
I have this model in LDD that has 3549 parts.
When I export to LDraw the model has 3475 parts.
So, I am missing 74 parts.
I am using the latest ldraw.xml file.
Some of the missing parts I can identify visually because I know they are supposed to be in the model looking at it in LDD and MLCad. Like part 15068 (Slope Brick Curved 2 x 2 x 0.667) which is in the LDraw libray and has the same partnumber in LDD. But it is not in the ldraw.xml file, so it does not export.
I found out that part 15254 (Arch 1 x 6 x 2) was missing and needed to be converted to 3307 which I did adjusting the ldraw.xml file, because it was already in there but needed the LDraw partnumber. This needly exported.
Still there are pieces missing that probably have different numbers etc. but are "hidden" inside the model so I cannot identify them visually.
My questions are:
1. How do I know or find out what parts do not convert to LDraw?
2. How to add them to ldraw.xml or adjust it so LDD exports the part to LDraw
I see there is lots of work to be done on ldraw.xml, so perhaps I can help a bit there.
Thanks!
Jaco

This is something separate? |

Hello!
I'm new.
So let me ask a new question: LDRAW is different from LDD (Lego Digital Designer 4.3.8?) If it is can I import/export betatween the two. Believe me it was awhile, before I suspected that perhaps I wasn't in Lego-Land. Or am I?
Thanks to all,
BC
