[LDPartEditor] 0.8.3b Beta Released

[Nils Schmidt]

Hello,

after three months I am proudly releasing LDPartEditor 0.8.3b


You can download LPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:

With this release you will be able to...

• ...configure shortkeys
  
• ...experience a faster program start.
  
• ...auto-detect and fix T-Junctions
  
• ...show the text line selection in the 3D editor as a selection (if the 3D editor is opened)
  
• ...enable Single Vertex Modification (aka SyncEdit) in the Text Editor when you select one vertex in the 3D Editor.
  
• ...benefit from a little performance gain (due to some modifications related to logging in the debug mode).
  

This release includes 10 important bug fixes as well.
The program was tested intensively with "real world" files. Especially, "Undo" and "Redo" should work now fine.

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 LPE.
   
4. On linux/mac, you have to excecute the shell script "run.sh" to start LPE.
   

Please note that this software is in the beta stage. Although, LPE 0.8.3b was carefully tested and developed, there are already known issues for this release. There is a potential risk of data loss.
Something can go wrong in about 100.000 lines of code.

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".
   

LPE 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 LPE on older machines as well.

System Requirements:

Minimum System Requirements:

• Java Runtime Environment (JRE) 1.7
  
• OpenGL 2.1 compatible Graphics Card
  
• Operating System (32/64bit): Windows [XP; Vista; 7 or newer], Mac OS X [>=10.6], Linux [e.g. Ubuntu Linux >=10.4]
  
• CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
  
• RAM: 2.5GB
  
• Video-Memory: 512 MB
  
• Free Disk Space: 100 MB
  

Recommended Requirements:

• Operating System (64bit): Windows 7, Mac OS X [>=10.6], Linux [e.g. Ubuntu Linux >=10.4]
  
• CPU: Multicore-Processor with 4 cores (or more)
  
• RAM: >4 GB
  
• Video-Memory: >512 MB
  
• Free Disk Space: 512 MB
  

--------------------------------------------------------------------------------
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:

Code:

This Java instance does not support a 64-bit JVM. Please install the desired version.

In general, I recommend to install the 64-bit version of the JVM.

edit: I put two releases in one post (0.8.3 and 0.8.3b)

Tomorrow evening I will add a new feature which was requested by a user:

When you select a vertex and do a "show in text editor", and the Text Editor switched to the "SyncEdit" mode and marked the locations where this vertex is used

The 0.8.3b release will also include a bugfix for a very rare issue where a selected vertex can't be merged to the nearest edge.

[Gerald Lasser]

Looking forward to this! Thanks

[Nils Schmidt]

I just updated the original post.

[Gerald Lasser]

I really like the selection of the single vertex which then switch to the SyncEdit. That makes many things much easier :-)

One question though: When I open DAT files via the text editor, the file is getting renered in the 3D editor, if I open the next one, this new one will be in the 3D editor.
Now I select the previous tab in the text editor and the 3D editor satys with the last element. Is there a way that the 3D editor will also switch? I could not make LDPE do so...

EDIT: Forget my question I just found a the place where to right click...

Hi,

I fixed some critical bugs in the last days.

You can download the bug fix from this page:
http://nilsschmidt1337.github.io/ldparteditor/
or simply use the updater.

Changelog:

With the release of 0.8.3c the following issues are fixed:

• An infinite loop, which could occur when "Single Vertex Replace Mode" was active ("SyncEdit")
  
• The Isecalc tool did not generate all intersection lines
  
• "Synchronise Folders..." did not work properly from time to time
  
• Undo/Redo triggered an infinite loop from time to time -> lead to data loss of unsaved changes (very annoying!!)
  

The program was tested intensively with "real world" files. Especially, "Undo" and "Redo" should work now fine.

I will release version 0.8.4 in the next week.

This version will include the new MeshReducer tool. It is designed to optimize CSG meshes.
The tool was already integrated in version 0.8.2d, but I was not happy with the implementation.
In 0.8.3 I deleted all the code for this tool and drafted a completely new and better design.

The new workflow for CSG is as follows:

1. Inline the !LPE_CSG COMPILE meta command
   
2. Run the TJunctionFinder tool
   
3. Check the result manually and do little improvements.
   
4. Run MeshReducer
   
5. Check the result again, run Rectifier...
