ChronosGL

A scene graph for WebGL written in Dart

Features:

  • MIT licensed
  • very high focus on simple, minimal and elegant code and API
  • lightweight and fast
  • capture keyboard and mouse events
  • all scene graph nodes position and rotation are based on a single matrix4 variable. this is likely the main differentiator to other scene graphs

  • space ship camera included
  • shapes: cube, cylinder, icosahedron and torusknot
  • pickray
  • points sprites ( very basic particles )
  • skybox
  • async texture loader with progress feedback
  • only Quaternion, Matrix4 and Vector3 math
  • great support for canvas based textures
  • focus on procedural content generation and textureless rendering

Some basic ideas:

  • ChronosGL contains getters for all important objects.
  • The main loop iterates over all ShaderPrograms
  • A ShaderProgam contains all Meshes that shall use its Shader
  • Camera extends Spatial
  • Node extends Spatial
  • Mesh extends Node
  • Nodes can contain child nodes and they inherit their parents transformation.

See doc/usage.txt for usage infos.
