Rendering on Windows Server 2008 Possible?

[kareem613]

hmm. All the jars in place and having compiler errors. It's been a while since dealing with java classpaths. Am I missing something?

Under Windows, you must replace : separators by ;

About rendering photos at the stored points of view returned by the method getStoredCameras in [font=courier new]Home[/font] class, you could replace the following two lines in [font=courier new]ConsolePhotoGenerator.java[/font]:

Code: Select all

    renderer.render(image, home.getCamera(), null);
   ImageIO.write(image, homePhoto.substring(homePhoto.lastIndexOf('.') + 1), new File(homePhoto));

by:

Code: Select all

    for (Camera camera : home.getStoredCameras()) {
      renderer.render(image, camera, null);
      int dotIndex = homePhoto.lastIndexOf('.');
      String cameraPhoto = homePhoto.substring(0, dotIndex) + "-" 
          + camera.getName().replaceAll("/|\\\\|:|;", "-").replace(File.pathSeparatorChar, '-').replace(File.separatorChar, '-')
          + homePhoto.substring(dotIndex);
      ImageIO.write(image, homePhoto.substring(dotIndex + 1), new File(cameraPhoto));
    }

and you should import [font=courier new]com.eteks.sweethome3d.model.Camera[/font] class.

Hello,
in he first place I want to thank You for developing such a nice tool.

I'm also trying to run the render in headless mode with SW3D 6.2 on a linux machine. I have fallowed You guide, but unfortunately I'm getting

No X11 DISPLAY variable was set, but this program performed an operation which requires it.
at javax.media.j3d.VirtualUniverse.<clinit>(VirtualUniverse.java:294)

error when trying to run it on a server. I have found Your post on jogamp about editing VirtualUniverse.java class, but I'm afraid it's to difficult for me. Are You able to provide modified version of j3dcore.jar just to make it more available to use it by broader group of people?

[Puybaret]

Are you sure you added the [font=courier new]-Dj3d.rend=noop[/font] option, as explained in my post of February 3rd, 2017?

[brute4c]

Yes I did. I had to edit j3dcore.jar and I was able to successfully render photos with default values. After setting property

Code: Select all

-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.highQuality.globalIllumination=path

console is flooded with warnings:

LIGHT warn : NaN shading sample!

so I'm not sure if it's actually rendering anything. Is there a way to resolve this issue or at least disable the warning?

[brute4c]

Just for the record, I have fallowed those steps to edit class in j3dcore.jar https://stackoverflow.com/a/14069149/9931119
and replaced the [font=courier new]if[/font] statement according to Your instructions: http://forum.jogamp.org/template/NamlSe ... ser=495956

This allowed me to run sh3d render with the [font=courier new]-Dj3d.rend=noop[/font] option. Unfortunately it's only working for the AO + Photon Mapping, when trying to render with Path option I'm getting a lot of warnings and in the end the output image is just black.

I would also like to use a option from PVR 1.9 to enable sky light but I don't have an idea how I can use the plugin in headless mode. Is there any way to do it?

[Puybaret]

You shouldn’t have to recompile Java 3D jars if you use the ones available here (actually, I just discovered that the links in my post of February 2017 have been out of date, since SourceForge.net forced me to move from CVS to SVN, but I just updated them).

I never tried to render an image with a plugin on a server but don’t see a reason why it couldn’t run. Did you try to render your image with the GUI first? And did you try with Sweet Home 3D 6.2 Jar?

Greetings. I'd like to present a wish list, ordered by importance:

• incremental output image name in case of homonymy to avoid overwriting existing images, and/or automatic output folder creation for each rendered .sh3d file;
• rendering queue composed of a list of .sh3d files;
• ability to use rendering engines other than the default Sunflow, and to change the engine;
• ability to change rendering settings, including time of the day, lens type, and ceiling lights.

Much obliged.

Gian1, Sweet Home 3D API will let you make these changes. Feel free to contribute to ConsolePhotoGenerator improvements.
