I am new to JUNG, I can display graphs in 2D but can anyone show me how to show 3d graphs.
You can't do this with JUNG from what I know. However you could use something like UbiGraph which has language bindings for Java so you would be able to communicate with it from a JUNG application.

I have been toying around with the Spark AR platform for making augmented reality filters and it's been going quite well. The only thing I would like to know, however, is if it is possible to create your own Face Distortion pack. I have been using the one offered by Spark AR but it just doesn't reach what I would like to achieve. I've managed to adjust the Face Distortion 3D object in 3DS max, but using that in Spark AR doesn't yield the correct results. Instead, any deformation I might adjust in the deformation settings will result in the face mesh just becoming larger.
Basically, does anyone have a better insight in how to use custom Face Distortion packs for Spark AR. Will provide more information if necessary of course. Any information welcome. Thanks!
I would like to create my own image target/marker to use with ARKit like Vurofia does.
I should use image analysis algorithm, detecting unique point of my markers
Vuforia generates a new image (XML+Image) with point clouds to identify each marker.
Are there alternative tools to create this? How can I achieve this?
I suggest you integrate OpenCV with ARKit, it`s possible.
OpenCV is a powerful library which allows you to do a lot of cv tasks, besides it`s flexible and c++ based.
I am trying to create spatial representation of features. Basically, an image is subdivided into grids, e.g. 4 grids, and features are detected for each grid. Features are clustered into visual words. Histograms are created for each grid and then I can match the corresponding grids with histogram intersection. Here is the paper http://www.vision.caltech.edu/Image_Datasets/Caltech101/cvpr06b_lana.pdf that I am working on it. First of all, how can I subdivide an image and detect features? I found out GridAdaptedFeatureDetector in Opencv but I do not know how to get features for particular grid. I can define a region of interest and detect features separately and add them into histogram but this sounds complicated and time wasting. Maybe there is an easy way to do. Any ideas are appreciated. Thanks in advance.
Your question is basically how one could implement her paper. The good news are that prof. Lazebnik has shared the source code or her Spatial Pyramid here:
http://web.engr.illinois.edu/~slazebni/research/SpatialPyramid.zip
Nevertheless, it is a matlab implementation that you would have to convert to OpenCV if you want.
You can also take a look at here slides and the dataset used is here.
I am just starting to dive into the world of 3D objects and perspectives, esp. in Flash.
My goal is to have a 3d coordinate system with grids plus the option to define x, y, z values of a vector to be plotted.
Simple example:
It would also be great to use the mouse to rotate the coordinate system, e. g. like in this video or here.
Does anybody know if there is such a tool or library that provides such a 3d coordinate-system? I would prefer Flash AS2/AS3 but this is not a must-be. The only requirement: The tool must be running within the browser, no use of software such as Blender or SketchUp.
Maybe somebody has already written a program like that?
Thank you.
PS: I know that there are web services like wolframalpha that can plot in 3d, but I need an interactive tool.
PaperVision3D is an opensource actionscript3 library that can handle all sorts of 3D rendering. http://code.google.com/p/papervision3d/ . I've used it for programs that give you a full 3D environment with typical 6 degrees of freedom.
Is there a visualization framework like JUNG for iOS?
I'd like to implement something similar to this.
Best graph plotting library for iOS is Core plot. It is very powerful, and easy to understand.
But for simple graphs you can use s7graphview library also.
If you want to do it yourself, you can do custom drawing using Core graphics.
