Is it possible to get the Z buffer of an image to be used as a simulation of time-of-flight camera or for simulating laser range finder or sonar? These would all be great for robotic simulations...

Space navigator would be good to support as a standard tool. We use them at UTSA, and when I get back to the lab in Texas, I may want to hook one up as well. Was it developed for cross-platform, or platform-specific? I may be interested in about a month from now. :)

I found this: And we need to tell java where to find the corresponding native libraries. This is done by the -Djava.library.path-flag: Isn't working yet. Under Construction ;) java -Djava.library.path=. de.jreality.tutorial.geom.Cube05 at http://www3.math.tu-berlin.de/jreality/mediawiki/index.php/Co...

Is this going into the SVN head? There's also the cylinder patch ( http://www3.math.tu-berlin.de/jreality/ ... ?f=7&t=622 )

Thanks

Thanks.. maybe getting a bit closer... I copied the entire classpath to the top of MATLAB's classpath.txt file /Users/ted/workspace/jr-practice/bin /Users/ted/workspace/jreality/bin /Users/ted/workspace/jreality/lib/antlr.jar /Users/ted/workspace/jreality/lib/jogl.jar /Users/ted/workspace/jreality/l...

Although that works to capture an image, if I want to capture a snapshot of an image from a different camera than the one that the GUI is displaying, I will have to switch to the snapshot view, take the snapshot, then switch back, which will cause the GUI display to flicker. Please correct me if I'm...

I want my scene to be fixed with respect to the SkyBox so that navigating simply moves the camera, and the scene will appear fixed to the ground. What is the recommended way of doing this? I don't want to mess with the core code if there's already a setting for this. I suppose I could take over the ...

I'm wondering how extensive are the differences? Perhaps it's one reason it's been giving me trouble trying to call from MATLAB on OSX.. . .

Not sure whether OSX or MATLAB or one of the toolboxes for it that I installed has too old of libraries or too new, but there may be conflicts somewhere...

I added a tutorial on how to make a skybox with a digital camera

Is the skybox in SkyboxAndReflMapExample supposed to appear mirrored? It does. Not just the reflection, but the actual background appears mirrored compared to the original 6 photos. I tried with TextureUtility.createCubeMap and TextureUtility.createReflectionMap, both give the same reflected result ...

I made a patch for the ends of the cylinder, but noticed the sides orientation is not quite what I would expect. It is inside-out and upside-down, rotated 90 degrees. Should I straighten all that out, or would it be an unacceptable risk to possible existing code that depends on the current cylinder ...

OK - when I implement I'll do it as a patch to existing libraries then. Aloha

It seems a best guess at a reasonable texture map should be made for the end caps, since an attempt is made for the sides of the closed cylinder. My suggestion is to map texture coordinates to best meet two design goals: 1. The texture should be about the same resolution as the side (1/PI x 1/PI) 2....

Here's what I tried on SnowLeopard OSX, using Juno Eclipse and Java 1.6.0_33 (mostly in tutorial format with screendumps removed) Post-install Configuration Start with JReality project in Eclipse. You will need to configure for your operating system to get off-screen rendering. RightClick jreality, ...

Still no dice... Any other ideas? These are the same jars and dynlib files that work fine in the Eclipse environment direct from SVN with only the JNI path updated to point to the mac osx folder...
