Re: Need help to understand what and how the tools work

The "evolution" matrix gives says how the PointerTransformation (see http://www3.math.tu-berlin.de/jreality/mediawiki/index.php/Tools_introduction ), has changed since it's last position. I.e., it is a matrix which gives the new PointerTransformation when multiplied (from the right) to the previous ...

Re: Spacenav?

The thing only works when spacenavd is installed. Thus, it will only work on linux. You should try to compile the code, which is under native/libspnav_java.tar.gz

Re: MatrixBuilder.invert ?

MatrixBuilder is used to create a matrix as a product of isometries, so "invert" would not fit with the semantics (and documentation). I think you should use Matrix.conjugate.

Re: Cumulative transform between two nodes?

All right, I forgot about that method. It will return all paths from one component to a node, in your case it is probably just one path. Still you need two paths, except if one component is an ancestor of the other.

Re: Cumulative transform between two nodes?

You can create a SceneGraphPath for each of nodes, both paths starting at the scene root. Then use path1.getMatrix and path2.getInverseMatrix and multiply them together. There is no utility function for this, because the paths might not be unique.

Re: Bad Rendering Result with the Jogl-Viewer

The easiest way would be to save the "content" node from the jreality viewer, as a jrs file. And, let us know about your hard- and software configuration, graphics card, os, graphics card driver.

Re: load 2 images together

just create a SceneGraphComponent and set the two components that you have loaded as its children. Then set this SceneGraphComponent as the content.

Re: JRViewer issues

Probably the data does not have texture coordinates. Otherwise you would see the texture.

Re: Creating a proxy scene graph

Charles, look into src-proxies/de.jreality.scene.proxy.smrj The class SMRJMirrorFactory would be replaced in your case by a simple visitor that creates shallow copies of SceneGraphNodes (just use SceneGraphUtility.copy for all except SceneGraphComponents), except for the geometries you want to share...

JRViewer, fullscreen toggle

There is a bug, when switching the JRViewer to fullscreen and back, it doesn't remember the visibility flag for the toolbox. Probably the same problem happens for the menubar, i didn't check that.
