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.

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

but they are not connected to this subject.

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.

Maybe the dragon pattern from the shields (3846P4C.DAT) could be used...

I there any working way to atach bitmap to Ldraw parts? Specifically for minifigs. There are almost all bitmaps from Minifigs series in LDD. I extract them from it, but i am thinking about attaching them to ldraw parts.

This early 90s pattern is still missing: Minifig, Head Moustache Red Goatee Pattern

There were 4 sets with 5 minifig which had this pattern. With today pattern creator this shouldn't be a big challange... at least not for the expirienced part/pattern authors.

Thanks in advance.
