Hi,

just a little bug-fix for Willy's 3D rotation problems under Linux Mint and the wireframe render mode issues with CSG optimisations.


[Image: imgDuke2.png]
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(2 bug fixes)

With this release the following critical issues were fixed:
  1. The CSG mesh optimisation was deactivated when one of the 3D view had the wireframe render mode enabled.
  2. Under linux mint it was not possible to rotate/translate the 3D view with the keyboard key (default keys: "M"/"L").
What will the next release 0.8.39 deliver? You will get more text-editor features and it will fix edge selection issues.



The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 120.000 lines of code.

Make sure that you choose the right architecture for your OS and Java Virtual Machine (JVM) (64bit or 32bit).
A short guide how to check if a 64bit JVM is installed on your system is located at the bottom of this message.

  1. Download the zip-Archive
  2. Extract the archive content to the location of your choice
  3. On windows, double-click "run.bat" to start LDPE.
  4. On linux/mac, you have to excecute the shell script "run.sh" to start LDPE.
Please note that this software is in the beta stage. Although, this version was tested, there are already known issues  for this release. There is a potential risk of data loss.

You can search for updates if you do the following steps:

  1. On windows, double-click "update.bat" to search for updates.
  2. On linux/mac, you have to excecute the shell script "update.sh".
I listen carefully to your requests and possible complaints. Please leave me a message, with your thoughts and wishes to further improve the software.

LDPE is a 3D CAD application: The overall system requirements are higher. While I recommend to use a powerful 64-bit multicore system, it could be possible, to run LDPE on older machines as well.

System Requirements:


Minimum System Requirements:
  • 64-bit Java Runtime Environment (JRE) 1.8
  • OpenGL 2.1 compatible Graphics Card
  • Operating System (64-bit): Windows [7 or newer], Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
  • CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
  • RAM: 4GB
  • Video-Memory: 1 GB
  • Free Disk Space: 100 MB
Recommended Requirements:
  • Operating System (64bit): Windows 7,8,10, Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
  • OpenGL 3.3 compatible Graphics Card
  • CPU: Multicore-Processor with 4 cores (or more)
  • RAM: >4 GB
  • Video-Memory: >1 GB
  • Free Disk Space: 512 MB
  • For a faster start, LDPartEditor and the LDraw™ library should be installed on an SSD.
--------------------------------------------------------------------------------
How to check your JVM version (32- or 64-bit):
--------------------------------------------------------------------------------

You can try on the command line:

Code:
java -d64 version

If it's not a 64-bit version, you'll get a message that looks like:
This Java instance does not support a 64-bit JVM. Please install the desired version.
I tried (better late than never!) to use the part review mode of LDPE. After doing so, I had to change back a lot of my settings (render mode, view actions, number of views). Could it be possible to save these settings when entering part review mode and restore them when exiting part review? Alternatively (since, as it is implemented, there is not really a part review mode to exit), I 'd like to be able to save all my user settings in a file, and restore it when I want to.

Maybe also it would be interesting to use part review mode locally (from a file on HD), before sending it on parts tracker?

I created issues for your ideas (#645 and #644).
There is a high chance that you'll get these features in the next year :)

Works! Thank you.

Trying to fix a vertex mismatch I discovered a problem with unificator, that deletes some surfaces from the unified mesh (and in an assymetrical way, makes me think of a subtle calculation bug...)
Attached the original file, result with command line unificator (default unification distance + snap on vertices, threshold 0.2), result with LDPE unificator using the same values.
Bug of the day:

1.) Reports the following errors:

* The part type information is missing
* The licences information is misplaced

on this header:


Code:
0 ~Animal Clam Bottom
0 Name: 30218k01.dat
0 Author: Willy Tschager [Holly-Wood]
0 !LDRAW_ORG Unofficial_Flexible_Section
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt


2. Save as... removes "Unofficial" from the 0 !LDRAW_ORG Unofficial_Flexible_Section line and saves it as: 0 !LDRAW_ORG Flexible_Section

Thanks for your bug report! I created an issue for the "Save As..." problem (#647).

Regarding the header hints: They are correct...

This part type is unknown:

Code:
0 !LDRAW_ORG Unofficial_Flexible_Section



It should be

Code:
0 !LDRAW_ORG Unofficial_Part Flexible_Section

This change will also resolve the misplaced license problem.

My bad. I overlooked "optional". An example should be added to:

Thanks! I will take a look.

edit: I created an issue for this problem (#650).
"Move selected subfile to manipulator" is a great tool to position a primitive in a known position/orientation (for example the knobs at the back of cap http://www.ldraw.org/cgi-bin/ptdetail.cg.../63351.dat). But could it be possible to keep primitive scaling when doing so? Currently it is reset to scale 1.

Losely related: on the contrary I sometimes wished to be able to unscale something without losing current origin/orientation.
