How to run src/mergingBodies3D/LCPApp3D on Mac OSX? #35

Open alecjacobson opened 4 years ago

alecjacobson commented 4 years ago

I'm looking forward to trying this demo. Thank you for sharing the code.

The README.md mentions running the app src/mergingBodies3D/LCPApp3D. I can't find that file. I do find src/mergingBodies3D/LCPApp3D.java, but it's been a long time since I've compiled/run java code.

I tried issuing javac src/mergingBodies3D/LCPApp3D but I got 100s of errors.

What's the right way to build/run the 3D demo?

I'm not one to try these things on the command line. Are you using oracle java? 1.8 is recommended due to the JOGL opengl bindings. The release has all the class files in a jar, and can be run if you just want to give it a spin, otherwise it is perhaps easiest to open it up in an IDE.

Here is a link to the release: https://github.com/EulalieCoevoet/AdaptiveMerging/releases/tag/20.05

alecjacobson commented 4 years ago

This got farther!

I downloaded the zip from that release then double-clicked on AdaptiveMerging.jar.

This window briefly appears, then disappears and the app closes. Not sure how to debug this.

I downloaded java from here https://www.oracle.com/java/technologies/javase-jdk14-downloads.html . I'm on a new mac laptop.

paulkry commented 4 years ago

oops... seems the release zip is missing the readme we included at submission time (the link for the JDK download). You shouldn't need to do anything more than click on the jar (would think java 1.8 would be best for JOGL). But that said, I wonder if the OSX migration away from opengl could be a problem. We've only tested on windows, and I suspect our gentle use of GLSL for shadows might be the thing that prevents the 3D view from opening (i.e., we use a compatability profile for Opengl... best mix of old and new). So much for cross platform simplicity of Java. Do you have a linux or windows machine on which to give it a spin?

alecjacobson commented 4 years ago

Other opengl apps (via C++) work OK on this mac. For example, if I compile and run https://github.com/alecjacobson/glversion I see

OpenGL version 4.1.0

Supported OpenGL is 4.1 INTEL-14.7.8

Supported GLSL is 4.10

paulkry commented 4 years ago

Yeah, the real issue is that we're not using a core OpenGL profile. I should really take the time to weed out all the old school OpenGL stuff from my code so we can drop the need for a compatability profile (there are probably not too many glBegins in the code, but they are there... for drawing points?). I think the JOGL OSX bindings will still work... Otherwise, perhaps we'll update the code to check if running on a MAC to turn off the GLSL shadow code.

EulalieCoevoet commented 4 years ago

Hi Alec,

Thank you for reporting this issue!

We just made some changes to the code for MacOS. With the latest version you should be able to run the app, and see the objects merge as you go through the examples. Unfortunately, it seems that the picking (interaction with the objects in the scene) may not work on MacOS, we're trying to fix that issue.

alecjacobson commented 4 years ago

Latest version still closes after briefly showing that window. If it would help I could send debug output; I just don't know where/how to get it.

paulkry commented 4 years ago

I might guess that if you are running the release from the command line, i.e., go to the folder and run "java AdaptiveMerging.jar" then it might dump some error messages onto the console? Alternatively, I have also seen that sometimes on macs the 3D view window opens but is super tiny and you need to make it bigger. You could also check that the command line is actually running the right version of java with a "java --version" command. I have two students with Macs that I'm recruiting to help debug this too... we saw it work on one mac so far, but perhaps it is an older machine with older OS and less OpenGL deprecation than your shiny new machine? I'd really like to fix this!

paulkry commented 4 years ago

The first warnings are expected, as JOGL is happier with java 1.8, and this MIGHT fix things, but I'm not sure it is worth installing an old version of java at this point on the off chance that it helps.

paulkry commented 4 years ago

I've committed a small program to probe what profiles are available. I've also pushed a runnable jar to make this easier (12 MB simply because it also contains the jogamp fat jar with opengl bindings). Run as "java -jar CheckGLProfiles.jar", and please let me know what you get! On my machine I get:

Default GLProfile is GLProfile[GL4bc/GL4bc.hw] Requested GL4bc Got GLProfile[GL4bc/GL4bc.hw] Requested GL3bc Got GLProfile[GL3bc/GL4bc.hw] Requested GL2 Got GLProfile[GL2/GL4bc.hw] Requested GL4 Got GLProfile[GL4/GL4.hw] Requested GL3 Got GLProfile[GL3/GL4.hw] Requested GLES3 Got GLException Requested GL4ES3 Got GLProfile[GL4ES3/GL4.hw] Requested GL2GL3 Got GLProfile[GL2GL3/GL4bc.hw] Requested GLES2 Got GLException Requested GL2ES2 Got GLProfile[GL2ES2/GL4.hw] Requested GLES1 Got GLException Requested GL2ES1 Got GLProfile[GL2ES1/GL4bc.hw]

Incidentally, I believe the bc endings mean "backwards compatible", so you can do all the cool core stuff in GL4 while mixing it with some glBegin( GL_LINES ) ... glEnd for quick hacking!

Ok... Thank you! Presuming that was with Java 1.8 on the new Mac, pretty discouraging. It probably runs somewhat now with Eulalie's updates on the old mac, without shadows. Seeing the core GL4 profile gives me incentive to update things... And I see jogl is still active with test builds this year, but the bindings we are using (last release) are now 5 years old, which is probably not helping. I'll leave this issue open (renamed to running on OSX) but I think we might be stuck here for now.
