• Integrating JavaFX Scene Builder in the IDEs

  - by Jerome Cambon

  I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.…

• Graph Isomorphism > What kind of Graph is this?

  - by oodavid

  Essentially, this is a variation of Comparing Two Tree Structures, however I do not have "trees", but rather another type of graph. I need to know what kind of Graph I have in order to figure out if there's a Graph Isomorphism Special Case... As you can see, they are: Not Directed Not A Tree Cyclic Max 4 connections But I still don't know…

• Finding most Important Node(s) in a Directed Graph

  - by Srikar Appal

  I have a large (˜ 20 million nodes) directed Graph with in-edges & out-edges. I want to figure out which parts of of the graph deserve the most attention. Often most of the graph is boring, or at least it is already well understood. The way I am defining "attention" is by the concept of "connectedness" i.e. How can i find the most connected…

• Class instance clustering in object reference graph for multi-entries serialization

  - by Juh_

  My question is on the best way to cluster a graph of class instances (i.e. objects, the graph nodes) linked by object references (the -directed- edges of the graph) around specifically marked objects. To explain better my question, let me explain my motivation: I currently use a moderately complex system to serialize the data used in my…

• Scene Graph for Deferred Rendering Engine

  - by Roy T.

  As a learning exercise I've written a deferred rendering engine. Now I'd like to add a scene graph to this engine but I'm a bit puzzled how to do this. On a normal (forward rendering engine) I would just add all items (All implementing IDrawable and IUpdateAble) to my scene graph, than travel the scene-graph breadth first and call…

• Scene Graph as Object Container?

  - by Bunkai.Satori

  Scene graph contains game nodes representing game objects. At a first glance, it might seem practical to use Scene Graph as physical container for in game objects, instead of std::vector< for example. My question is, is it practical to use Scene Graph to contain the game objects, or should it be used only to define scene…

• Updating scene graph in multithreaded game

  - by user782220

  In a game with a render thread and a game logic thread the game logic thread needs to update the scene graph used by the render thread. I've read about ideas such as a queue of updates. Can someone describe to a newbie at scene graphs what kind of interface the scene graph exports. Presumably it would be rather complicated.…

• Is finding graph minors without single node pinch points possible?

  - by Alturis

  Is it possible to robustly find all the graph minors within an arbitrary node graph where the pinch points are generally not single nodes? I have read some other posts on here about how to break up your graph into a Hamiltonian cycle and then from that find the graph minors but it seems to be such an algorithm would require…

• Best Planar graph program

  - by brian

  In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. What is the best open source program for drawing the planar graph with support of input nodes size and fixed drawing boundary region

• Split a 2D scene in layers or have a z coordinate

  - by Bane

  I am in the process of writing a 2D game engine, and a dilemma emerged. Let me explain the situation... I have a Scene class, to which various objects can be added (Drawable, ParticleEmitter, Light2D, etc), and as this is a 2D scene, things will obviously be drawn over each other. My first thought was that I could have…

• Scene transitions

  - by Mars

  It's my first time working with actual scenes/states, aka DrawableGameComponents, which work separate from one another. I'm now wondering what's the best way to make transitions between them, and how to affect them from other scenes. Lets say I wanted to "push" one screen to the right, with another one coming in at the…

• Using the new CSS Analyzer in JavaFX Scene Builder

  - by Jerome Cambon

  As you know, JavaFX provides from the API many properties that you can set to customize or make your components to behave as you want. For instance, for a Button, you can set its font, or its max size.Using Scene Builder, these properties can be explored and modified using the inspector. However, JavaFX also provides…

• Looking for a small, light scene graph style abstraction lib for shader based OpenGL

  - by Pris

  I'm looking for a 'lean and mean' c/c++ scene graph library for OpenGL that doesn't use any deprecated functionality. It should be cross platform (strictly speaking I just dev on Linux so no love lost if it doesn't work on Windows), and it should be possible to deploy to mobile targets (ie OpenGLES2, and no crazy…
