What exactly do you have issues with?

spark vapor Oct 30, 2023, 8:02 PM

#

so, the packaging works fine as far as i can tell

#

but i'm stumped on how to use the visualiser mentioned there

#

from the github part that is mentioning it, i understand there's a separate project (local web app) that takes in a json generated by the packaging project

#

but i'm lost

and you might need this in your pom.xml:

        <dependency>
            <groupId>com.github.skjolber.3d-bin-container-packing</groupId>
            <artifactId>visualizer-api</artifactId>
        </dependency>

spark vapor Oct 30, 2023, 8:17 PM

#

so i just copy that class to my project and add this into my pom and that's it?

tame agate Oct 30, 2023, 8:18 PM

#

I don't know that project

spark vapor Oct 30, 2023, 8:18 PM

#

what project?

tame agate Oct 30, 2023, 8:18 PM

#

3d-bin-container-packing

spark vapor Oct 30, 2023, 8:19 PM

#

oof.. i understand

tame agate Oct 30, 2023, 8:20 PM

#

but that file might be helpful in understandinghow to work with it

spark vapor Oct 30, 2023, 8:57 PM

#

so i tried opening the project visualizer-packaging but pom's got some errors

#

tame agate Oct 30, 2023, 9:09 PM

#

I guess the test artifact isn't published to the repository

#

you probably don't need the whole project

spark vapor Oct 30, 2023, 9:22 PM

#

well... i managed to fix some imports...

#

i'm down to this one..

#

my pom is fine tho

#

and the class is there.... https://github.com/skjolber/3d-bin-container-packing/blob/master/extreme-points/src/main/java/com/github/skjolber/packing/ep/points3d/SimplePoint3D.java

i am confused

tame agate Oct 30, 2023, 9:32 PM

#

Did you reload the Maven project?

spark vapor Oct 30, 2023, 9:33 PM

#

yep

tame agate Oct 30, 2023, 9:33 PM

#

oh

#

it seems like that class doesn't exist in the 3.x version

spark vapor Oct 30, 2023, 9:34 PM

#

this is so frustrating... why is someone posting something broken 😦

tame agate Oct 30, 2023, 9:35 PM

#

?

#

it isn't broken, it's just from a different version

spark vapor Oct 30, 2023, 9:35 PM

#

ok so what version is it?

tame agate Oct 30, 2023, 9:35 PM

#

looks like 4.whatever

#

which may not be released yet

spark vapor Oct 30, 2023, 9:36 PM

#

damn...

#

can i import the package locally and not from central repo?

tame agate Oct 30, 2023, 9:37 PM

#

if you want to find everything from the 3.x version, see https://github.com/skjolber/3d-bin-container-packing/tree/3.x

GitHub

GitHub - skjolber/3d-bin-container-packing at 3.x

A variant of the Largest Area Fit First (LAFF) algorithm + brute force algorithm - GitHub - skjolber/3d-bin-container-packing at 3.x

#

you could get the current 4.snapshot version by building it yourself, yeah

#

essentially clone the thing and run mvn install in the root directory

spark vapor Oct 30, 2023, 9:37 PM

#

ok let me see

``` this is killing me..

tame agate Oct 30, 2023, 9:38 PM

#

Did you run it in the root directory of the cloned project?

#

like you'd need to build the whole project

spark vapor Oct 30, 2023, 9:39 PM

#

misunderstood which root dir

tame agate Oct 30, 2023, 9:39 PM

#

not just the extreme-points module

spark vapor Oct 30, 2023, 9:39 PM

#

running

tame agate Oct 30, 2023, 9:39 PM

#

but alternatively, you can also use 3.0.9

#

and look at the repository and the examples there

spark vapor Oct 30, 2023, 9:41 PM

#

tame agate Oct 30, 2023, 9:41 PM

#

seems like some test failed

#

I don't recommend doing that but it would be possible to use -DskipTests

spark vapor Oct 30, 2023, 9:43 PM

#

alright

#

so now how do i use the module?

tame agate Oct 30, 2023, 9:43 PM

#

just change the version

#

to 4.0.0-SNAPSHOT

#

but this will only work on your computer

spark vapor Oct 30, 2023, 9:43 PM

#

well, i mean the module project builds fine now

#

#

so i tried running visualizationTest...

tame agate Oct 30, 2023, 9:48 PM

#

you can also take a look at VisualizationTest with the 3.0.9 version

spark vapor Oct 30, 2023, 9:48 PM

#

tame agate Oct 30, 2023, 9:49 PM

#

yeah, that test is marked as disabled

spark vapor Oct 30, 2023, 9:49 PM

#

so from what it said on github ```To use the visualizer during development, make your unit tests write directly to a file in the project (see VisualizationTest example).

tame agate Oct 30, 2023, 9:50 PM

#

I think that's for contributing to the repository but idk

spark vapor Oct 30, 2023, 9:50 PM

#

it should've made this file

#

and it did but...

tame agate Oct 30, 2023, 9:51 PM

#

I don't know that project ¯_(ツ)_/¯

spark vapor Oct 30, 2023, 9:52 PM

#

heyooo it worked

#

now i gotta figure how to make this into an app

tame agate Oct 30, 2023, 9:55 PM

#

if you really want to use it, you might want to use a version that's actually released

spark vapor Oct 30, 2023, 11:47 PM

#

thanks a lot for all the help man 🙂 you're a hero
