Trying to get HiDPI working - SH3d 6.3, Ubuntu 18.04

[gar37bic]

Folks,
I'm running an HP x360, Ubuntu 18.04. I'm trying to get SH3D running in HiDPI mode. I've tried the various suggestions I've seen, so far without any success - the program runs but it's all tiny. My most recent method was to edit the SweetHome3D shell script to run my local copy of java 13 (actually zulu-13). This runs fine AFAICT but is still not HiDPI.

The change I made was just to replace "$PROGRAM_DIR/jre8/bin/java" with /usr/bin/java, since my default java is now zulu-13.

I also tried adding -Dcom.eteks.sweethome3d.resolutionScale=2 to the script but that didn't make any difference. This is not my area of expertise, that was just shooting in the dark...

For completeness, here is the relevant part of my revised script:

Code: Select all

exec /usr/bin/java -Xmx2g -classpath "$PROGRAM_DIR"/lib/SweetHome3D.jar:"$PROGRAM_DIR"/lib/Furniture.jar:"$PROGRAM_DIR"/lib/Textures.jar:"$PROGRAM_DIR"/lib/Examples.jar:"$PROGRAM_DIR"/lib/Help.jar:"$PROGRAM_DIR"/lib/batik-svgpathparser-1.7.jar:"$PROGRAM_DIR"/lib/jeksparser-calculator.jar:"$PROGRAM_DIR"/lib/iText-2.1.7.jar:"$PROGRAM_DIR"/lib/freehep-vectorgraphics-svg-2.1.1b.jar:"$PROGRAM_DIR"/lib/sunflow-0.07.3i.jar:"$PROGRAM_DIR"/lib/jmf.jar:"$PROGRAM_DIR"/lib/java3d-1.6/j3dcore.jar:"$PROGRAM_DIR"/lib/java3d-1.6/j3dutils.jar:"$PROGRAM_DIR"/lib/java3d-1.6/vecmath.jar:"$PROGRAM_DIR"/lib/java3d-1.6/gluegen-rt.jar:"$PROGRAM_DIR"/lib/java3d-1.6/jogl-java3d.jar:"$PROGRAM_DIR"/jre8/lib/javaws.jar \
	-Djava.library.path="$PROGRAM_DIR"/lib/java3d-1.6 \
	-Djogamp.gluegen.UseTempJarCache=false \
	-Dcom.eteks.sweethome3d.applicationId=SweetHome3D#Installer com.eteks.sweethome3d.SweetHome3D \
	-Dcom.eteks.sweethome3d.resolutionScale=2	\
	-open "$1"

Could you try with [font=courier new]"$PROGRAM_DIR/jre8/bin/java"[/font]?

I did that first, and the app came up but it was not in hidpi mode, very tiny. That's why I tried modifying the script as shown above, after I tried all the things I found online. I'm open to suggestion

Following up, I've tried the following - it seems to work exactly the same in all cases.
- 6.3 download, stock
- 6.3 modified as shown above
- Ubuntu distribution version
- 'Portable' all architecture version
I also tried to get the Java Web Start version working with suggested parameter mod (" -Dcom.eteks.sweethome3d.resolutionScale=2") I don't recall if I got that working, but if I did it was just the same.

I'd just like to add that I used SH3d a number of years ago on a different project with great success. I appreciate the effort all y'all have put into this, and I'm confident that we can make it work!

Just solved it (not very clean). I'm running Arch and I just hacked the /usr/bin/sweethome3d script.
I've just added the -Dcom.eteks.sweethome3d.resolutionScale=2 in the options of the launch command and it worked like a charm.
I guess I'll have to redo the same after the next update ) So I will document it right now.
Hope this helps
Jean-Pierre

Thanks for your feedback. Setting the [font=courier new]com.eteks.sweethome3d.resolutionScale[/font] property is not wrong [;)]
