[LDPartEditor] 0.8.37 Beta Released (Critical Bug Fix) - Nils Schmidt - 2017-08-30

Hi,

here is a release which wipes out some critical bugs.

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

Changelog:
(7 bug fixes)

The following critical issues were fixed:

  1. Edger2 created duplicated TYPE 2 lines which were hard to spot.
  2. The primitive text search field was sometimes failing / sometimes primitives were not shown at all.
  3. Edger2 only created condlines if the adjacent surfaces vertices matched perfectly.
  4. Undo/Redo did not work with the CSG_EXTRUDE meta command.
  5. CSG inlining did not use all CPU cores.
  6. The new numeric input fields were blocking the common thread pool (no crash, only performance degradation).
  7. There was an endless loop regarding the new numeric input fields (no crash, only performance degradation).

What will the next release 0.8.38 deliver? A new CSG engine with great triangulation features...



The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 100.000 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, 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.


New CSG Engine - Nils Schmidt - 2017-09-18

I am working on a new CSG engine which will generate less triangles and a better overall triangulation.
There are already some promising results, but I need to define more testcases to deliver a rock-solid implementation in the end.

An incentive to finally learn CSG in LDPE Wink
...and thanks for the headup, I somehow missed that release announcement (and did sometimes noticed a slowdown - nice to know it's fixed now!)


RE: [LDPartEditor] 0.8.37 Beta Released (Critical Bug Fix) - Willy Tschager - 2017-09-20

Bug of the day:

* No notification pop-up when update is completed
* Prog does not store my full screen window status but reopens the window a bit smaller
* Prog does not store the status of the "Move adjacent data" button. Launches always with unpressed status
* Adding a blank while in "Triple manipulation" in the text editor causes havoc. I would expect that the rectangle around the triples are a safe harbour as long as I don't select something else independently what I'm inserting.

You could use the code for the Jurassic World Sphere to test:

I managed to do it with different steps and with Intersector to reduce the number of triangles. I promis I finish the part soon, right now comparing it to the LDD version
