Dec 21, 2003 · The beauty about scene graphs is they're not hard coded, specific things such as rotations, rendering, and any type of node you can think of are, but the way the scene is displayed is not. With our new found knowledge we can make this scene a lot more complex, so let's do it!

Scene graphs consist of a number of scene nodes, kept together in a tree-like structure - each node has a parent node, and a number of child nodes. So, our car example could be represented by the following scene graph:

Scene graphs can take a lot of forms: register or not the parent, list or contiguous buffer to store the children, flags... Firstly, we will see a quick example of it. In a second time, we will see simple optimizations to improve it.

Mar 15, 2011 · What is a scene graph? A Scene graph contains all of the geometry of a particular scene. They are useful for representing translations, rotations and scales (along with other affine transformations) of objects relative to each other. For instance, consider a tank (the type with tracks and a gun).

Dec 10, 2008 · By dynamically building the scene tree from a set of rules at run-time, we can support true scene graphs (scene graphs with cycles in them) as well as the ability to host environments with objects of drastically different scales …

May 5, 2010 · As the name suggests, a scene graph is data structure used to organize a scene in a Computer Graphics application. The idea is that a scene is composed of several different parts, and somehow these parts have to be tied together.

Scene graphs are used to manage and organize complex scenes. They help arrange objects, especially when transformations like rotation, translation, or scaling are involved. By using a hierarchical structure, scene graphs make it easier to manipulate objects in a scene.

For some engine's needs a simple list of objects in the world with frustum culling is enough. But for modern game engines this will just not suffice in most cases. This is why a scene graph is needed. Through this article I will explain the theory behind a scene graph then dig deep into the workings of this device.

Scene graphs have two kinds of branches: content branches, containing shapes, lights, and other content, and view branches, containing viewing information. This division is somewhat flexible, but we will focus on a standardized approach to give students a framework to build their work upon.

A scene graph is a general data structure commonly used by vector-based graphics editing applications and modern computer games, which arranges the logical and often spatial representation of a graphical scene.
