Viz - Render


A traversal of a scene will send graphical operation to an rendering engine.


traversal :

  • in 2D, the Painter's algorithm: start at the root and then recursively draw the child nodes. The tree's leaves represent the most foreground objects. Drawing proceeds then from back to front (closer objects overwrite farther ones).
  • In 3D, depth buffers, draw the closest objects first, farther may not be rendered as they are occluded by nearer objects.
