- Galaster - A 3D Dynamic Graph Visualizer
** Overview
Galaster is a system for visualizing dynamic graphs, the goal of this project is to create an opensource version of ubigraph. Currently it could work as a static C++ library, RPC APIs for other programming languages will be implemented soon.

** How To Build
You need GLFW, FreeType and CMake to build this project. The following command builds the static C++ library =libgalaster.a= as well as all examples included in this project.
#+BEGIN_SRC shell mkdir build cd build cmake .. make #+END_SRC
Once you successfully built this project, you can launch an example to see if it
works fine. Type =./examples/cube= to launch the cube example, which layout 1000
nodes as a 10x10x10 cube. You will get a very primitive window for interactively
viewing the graph.

Though rotating the graph through mouse dragging is currently unsupported, a number of keystrokes are recognized:
|Key |Function | |, |x-axis rotation | |, |z-axis rotation | |w, s |zoom in/out | |f, b |zoom way in/out | |r |reset vertices to random positions | |m |toggle solid/particle mode | |a, n, ... |useful in particular examples (binary_tre, membrane, etc.)|
** Future Works
- RPC based API and bindings for various programming languages
- +Spline edges and arrows+
- +Fast repulsion force calculation algorithm+
- +Rendering text labels+
- +Smarter auto camera+
- +Proper rendering options to make edges look consistent in various view angles+
