[LDPartEditor] 0.8.18 Beta Released


[LDPartEditor] 0.8.18 Beta Released
#1
Hi :)

next small increase to version 0.8.18... well, this time its clear what 0.8.19 will bring ;)

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

Changelog:
(4 new features and 3 bug fixes)

With this release you will be able to...
  • ...trigger "Show selection in Text Editor" from a button on the GUI of the 3D editor.
  • ...benefit from the fact that selecting "Show Selection In Text Editor" jumps to the next selected line.
  • ...benefit from the fact that a change to the colour palette is updated instantly on all editor windows.
  • ...customize the colours of the selection cross (3D editor)

The following critical issues were fixed:


  1. Wrong BFC rendering for primitives (in the primitve area)
  2. TJunctionFinder eliminates lines at random (normal mode)
  3. The "(!)" sign is set for (part) files which are created by the PartReview tool. This is not desired. (the "(!)" sign indicates that the file is located outside the project or the library structure of the project)

What will the next release 0.8.19 deliver? Bug fixes (selection, icons, text editor selection highlight) , usability  improvements (tabs on the 3D editor), maybe some new fancy 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, LDPE 0.8.18 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:
  • Java Runtime Environment (JRE) 1.8
  • 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: 4GB
  • 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: >=1 GB
  • 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 for Java 8.

I was able to download and install it fine from github, but it seems that the updater still fetches version 0.8.17.

Bug of the day:

* LDPE now launches without opening the text editor. Opening a part you either get a text editor and 3d without any content or the part gets opened in 3d but no text editor gets launched and you have to "Open in Text Editor" in the parts tree
* I'm moving the first steps into CSG. Rotating a part at 90 degree you get undesired digits. Check:

0 !LPE CSG_ELLIPSOID a  1 0 0 0 1 0 0 0 1 0 0 0 1
0 !LPE CSG_ELLIPSOID a 1  0.0 0.0 0.0 1.0 0.0 0.0 0.0 0.0 1.0 0.0 -1.0 0.0

w.

PS. I'll come back for more CSG questions so bare with me. 'Til then I would appreciate if you could add pics for 0 !LPE CSG_QUALITY [3 to 48] to your wiki.

Bugs / Tabs in the 3D Editor
#6
I make some progress with the implementation of tabs for the 3D editor.
The 'Sync' button will get an icon. It activates/deactivates the synchronisation between the selection of tabs in the 3D editor and text editor.
  • Selecting a tab in the text editor will select the tab in the 3D editor (and display the part in the 3D editor)
  • Selecting a tab in the 3D editor will select the tab in the text editor (and display the part in the text and the 3D editor)

This is a desired behaviour. Some users complained about the text editor window (they had to close it every time).
Maybe I can add some option to enable/disable the text editor on start?

Thanks! :)
I fixed it.
The issue will be gone with release 0.8.19.

I identified the root cause! Currently, LDPE is not able to reload a file which has unsaved changes.
What you really want: A question dialog with the possibility to revert all changes or to continue your work on the modified file.

I created a ticket. The feature will be inlcuded in version 0.8.19 Smile

30082.dat

I tried to use CSG to rebuild to cut sphere. Here is what I came up with, based on your tutorial on the wiki:

0 // The COMPILE command displays the CSG volume on the screen
0 // Inlining the following line will generate triangles of the CSG volume
0 !LPE CSG_COMPILE u


I also inlined the compiled U but was not very happy with the output, so I guess there is room for improvement of my code. Any help and suggestion is welcomed.

PS. It would help if you could offer a raw code like 0 !LPE CSG_CUBOID    x c  0 0 0 1 0 0 0 1 0 0 0 1 from a drop-down box in the toolbars for the primitives and the operators so I don't have to check back with the wiki.

Tab feature is complete...
#12
Information 
You can now (with the upcoming milestone 0.8.19)
use tabs to select, open and close a recently used file from the current session.
The two yellow arrows enable the synchronisation between the tab selection in the 3D and text editor.
If you select a tab in the 3D editor, it gets selected in the text editor and vice versa.

Apart for leaning purpose I really don't think it's a good idea to really cut the sphere. Interpenetrating cyli/sphe primitives will give a much better visual result and simpler code. There is an existing cyli to sphe primitive too (not on my computer, can't find it)

Are you thinking of 4-4cyl1sph2.dat?

Well, the CSG code is fine... To clean the output, I normally exploit part symmetries to save some work and finally use the MeshReduce tool and do some manual tweaking.
It is extremly difficult to "automagically" optimise these CSG meshes very fast (without destroying them).
I appreciate any technical advice how I can improve the output quality.
Maybe someone nows a better CSG algorithm?

Here are my authoring results (no primitive substitution):

Guidelines for good bug reports / feature requests
#5
Bug 
Hi,

I just want to give you some advice for good feature requests / bug reports (again):

  1. Describe precisely what you observe. Take a screenshot or record a movie if needed.
  2. Say clearly what you want. Make a sketch or a mockup.
  3. Be precise as possible. Everybody should be able to understand what you want to say.
  4. If you say some application behaviour is wrong, my interest is to know what is right instead.
  5. Do not make use of ambiguousness and colloquialism.
Some very good approaches for agile projects like LDPE are User Stories.
One sentence, starting with "As a user I want..." is what I like and how I describe most of the ideas I got.

E.g.
As a user I want to customize the colours of the selection cross (3D editor)

I need clean feedback to estimate the effort it takes to fix a bug / to implement a feature.
Otherwise, I can't fix it (even if I wanted to).

Leg godt

Nils

RE: [LDPartEditor] 0.8.18 Beta Released (Show selection in Text Editor / bugfix)

Feature request of the day:

* As a user I'd like to have a wrapper window, which would full-screen either the Text or the 3D pane with a click in the right top-hand corner or split the two panes with a divider I can move with the mouse:

   

this would IMHO make the handling of the two editors much easier and the continuous taskbar-clicking superfluous.

I created a ticket.

However, your request is really hard to implement. SWT does not support MDI and there exists a ton of business logic for the two editor windows due to the fact that the 3D and the text editor are simply seperate windows.

They are synchronised (which was very complicated to implement!) and access each other in different ways.
It is also possible to use more than one text editor and to drag and drop the tabs to another text editor instance.
I highly doubt that I am able to refactor the whole application for just a two or ten less clicks on the taskbar.

To seperate the text from the 3D editor was the first design choice for LDPE I made about five years ago...
Nevertheless... I will find a way.
