How do I calculate the cumulative sum or total of transformation matrices passed down from parent to child to grandchild, etc.?

The docs say:

Quote:Formally, the transformed point (u', v', w') can be calculated from point (u, v, w) as follows:
u' = a*u + b*v + c*w + x
v' = d*u + e*v + f*w + y
w' = g*u + h*v + i*w + z

Whenever I click on a part in activity list, I get something like "File 'parts/65418.dat' was not found in Unofficial parts library."

I wanted to check with you, who has used LDPE to produce "organic parts" which are only in system given their bounding box.

I selected the Correlian Hound (36032) to try modelling my first part.

So far this is the result I can share no. It went pretty smooth, actually smoother than I thought I have to say. Now the touching up of the tail part and the modeling of the head is pending.

My approach was to take orthogonal pictures and trace the main lines with triangles in LDPC, import those into LDPE and move the vertices around...

Anybody having a different approach?

   

Big shout out to the LDRAW community and Roland Melkert for LDCad! And Rebrickable!
I trained a machine learning algorithm to recognize pictures of bricks, using an animation I made in LDCad. With a parts list from Rebrickable. And parts from LDraw of course. 
My ideal scenario is to grab a handful of bricks, toss them on the table, take a picture, and have the program catalog the pieces.

I put all the how-to details in an article on medium. https://towardsdatascience.com/machine-l...12e0544012
I am working on some other ideas for machine learning brick projects. And it would be cool if people have feedback or wanted to collaborate.

I updated the new LDRAW ALL IN version. There is no problem in the modeling by MLCAD. But when I run the POV file exported from LDRAW, the wrong message is as below.
I checked the before POV file made by old LDRAW ALL IN version, there is no problem. I don't know if there is any option need to setup. Thanks a lot.

I'm starting to write my own parser that will convert an MPD file to JSON format.

Are the FILE, Name:, Author:, !LICENSE, ROTATION properties case-sensitive? Will they always be the same case as I typed them or should I ignore case?

Thanks.

In case anyone has wondered what happens when you accidentally double click a part in the parts bin after a Select All:

   

I know I have posted this before, but I've been making the Datsville HD render more interactive.

You can click on the buildings (only one so far) and a popup blurb will appear with a message from a Datsville resident.

Not sure how much further I will go with this. It depends on how much I can automate the process, since I plan on making further revisions to Datsville itself too.
