jReality - the forum

Hi, I have created a coordinate system using CoordinateSystemFactory. I would like to make the labels on the coordinate system visible and readable. For this factory object, I tried various values of label scale, font sizes and fonts, and I get the same result - the labels are unreadable. I also che...

I solved the problem. There are couple of places you can set values to axisScale: while creating CoordinateSystemFactory, and by using the setAxisScale() method. They were in conflict, in my program. When I corrected it (and I chose a very large value for axisScale), jReality set up the coordinate s...

I have wide ranging data. For example, each coordinate can have values anywhere from 1.0 to 30,000.00. I created a SceneGraphComponent from this data, and then created an object of CoordinateSystemFactory, the object froze. I traced the problem to a method getBoxTicks() in CoordinateSystemFactory. I...

Thank you very much, Charles! It worked!

Thanks again!

Thanks Charles! I tried your suggestion along with increasing the point size radius, and tried three different types of viewers. All of them do not display any points. I tested for various "far" distances and the result is the same. Here are the viewers I constructed based on your suggestion. public...

Thank you, Charles! I looked through the code of jReality for Clipping Planes. It appears that the clipping planes (near and far) are st in only one class, DefaultPerspective. This class is used in PolygonPipeline, which in turn is used in AbstractViewer (of de.jreality.soft, not the one in jogl). A...

The following data is a set of 100 (of 209) points with widely ranging values. This data comes from a data mining program called Weka (data file: cpu.arff). The JRViewer does not display the data (only first three coordinates were considered for the display). But if this data is normalized by the co...

To address the question I raised in my previous post about bringing the bounding box into the viewing volume, I found some code in jReality that can do it. It is in the JRViewer and CameraUtility classes. I took some code from the tutorials and added it to my code. Unfortunately, it is not working -...

Thank you for the prompt reply. There seems to be two issues - I am sorry I did not make them clear. One of the constraints on "point cloud" display is to show the correct coordinates of the points. If we multiply by a factor, as you suggested, the points displayed will not be correct. You answered ...

I am trying to display a (relatively) large (209) set of groups of points. I took some code from geom tutorials and then tried on a simple set of groups of points. double [][] vertices1 = new double[][] { {0, 0, 0}, {1, 0, 0}, {1, 1, 0}, {0, 1, 0}}; double [][] vertices2 = new double[][] { {0, 0, 0}...

I am able to download successfully this morning.

Thanks!

Hi, I am trying to download from subversion repository: http://fs.math.tu-berlin.de:8000/svn/jreality I keep getting the following error. Error validating location: "org.tigris.subversion.jahl.ClientException: RA layer request failed svn: Server sent unexpected return value (500 Internal Server Erro...

I solved the problem by using startupLocal() method of JRViewer, which produces
JRootPane object.

Thanks!

Hi, I need to add multiple "ViewingComponents", created from different Viewers, to a JFrame object. When I tried to do it using a JPanel to each ViewingComponent, and then adding it to another JPanel (mainPanel), and finally adding it to a JFrame gives me a blank window. You can reproduce the result...

Hi, I wanted to tell you about an exciting application I have been developing over jReality: a Visualization System that supports multiple pipelines. I use jReality in two ways. I use it for visualization of scenes. I also have simple a scene graph, which is grounded in jReality scene graphs. I put ...
