The scene graph would have a 'horse' node with a 'knight' node attached to it. The scene graph may also describe the spatial, as well as the logical, relationship of the various entities: the knight moves through 3D space as the horse moves. In these large applications, memory requirements are major considerations when designing a scene graph.
Examples of free and open-source scene-graph canvas options include: in C, Evas (in EFL) from the Enlightenment project; in C, Clutter, associated with the GNOME project; in C, GTK Scene Graph Kit (GSK) in C++ or optionally in Qt's own markup language QML: Qt Quick, provides a scenegraph Archived 2013-10-29 at the Wayback Machine associated ...
OpenSG is a scene graph like many others, but with a number of unique features that set it apart from others. It features a blocked state management system to reduce the overhead for state change optimization, highly flexible traversal and other mechanisms to allow run-time exchange and enhancement of core data structures, but the most unusual aspect is its multi-threading approach.
The R programming language can be used for creating Wikipedia graphs. The Google Chart API allows a variety of graphs to be created. Livegap Charts creates line, bar, spider, polar-area and pie charts, and can export them as images without needing to download any tools. Veusz is a free scientific graphing tool that can produce 2D and 3D plots ...
Rendering can produce images of scenes or objects defined using coordinates in 3D space, seen from a particular viewpoint. Such 3D rendering uses knowledge and ideas from optics , the study of visual perception , mathematics , and software engineering , and it has applications such as video games , simulators , visual effects for films and ...
POV-Ray is a free general-purpose constructive solid geometry ray-tracing package with a scene description language very similar to many programming languages. It can also render parametric surfaces and algebraic surfaces of degree up to seven, as well as triangle mesh approximations using the "mesh" and "mesh2" object types and "param.inc" .
scenes, OOP, metaprogramming Looks: Controls visibility, costumes, and output Sensing: All sprite hit detection and user input Sound: Plays audio files and programmable sequenced audio Operators: Mathematical, text, and Boolean operators; lambda Pen: Write, draw, or stamp on stage Variables: Variables, lists, including lists of lists, lists of ...
The core of OpenSceneGraph provides classes and methods for construction and manipulation of the scene graph. It contains classes representing various types of nodes , scene geometry, OpenGL state abstraction, geometric transformations , as well as mathematical classes for 2D and 3D vector and matrix operations .
