A Display is a container of {@link SceneJS_Object}s which are created (or updated) by a depth-first + * compilation traversal of a {@link SceneJS.Scene}. + * + *

Rendering Pipeline

+ * + *

Conceptually, a Display implements a pipeline with the following stages:

+ * + *
    + *
  1. Create or update {@link SceneJS_Object}s during scene compilation
    2. + *
  2. Organise the {@link SceneJS_Object} into an object list
    3. + *
  3. Determine the GL state sort order for the object list
    4. + *
  4. State sort the object list
    5. + *
  5. Create a draw list containing {@link SceneJS_Chunk}s belonging to the {@link SceneJS_Object}s in the object list
    6. + *
  6. Render the draw list to draw the image
    7. + *
+ * + *

An update to the scene causes the pipeline to be re-executed from one of these stages, and SceneJS is designed + * so that the pipeline is always re-executed from the latest stage possible to avoid redoing work.

+ * + *

For example:

+ * + *
    + *
  • when an object is created or updated, we need to (re)do stages 2, 3, 4, 5 and 6
    • + *
  • when an object is made invisible, we need to redo stages 5 and 6
    • + *
  • when an object is assigned to a different scene render layer (works like a render bin), we need to redo + * stages 3, 4, 5, and 6
    • + *
  • when the colour of an object changes, or maybe when the viewpoint changes, we simplt redo stage 6
    • + *
+ * + *

Object Creation

+ *

The object soup (stage 1) is constructed by a depth-first traversal of the scene graph, which we think of as + * "compiling" the scene graph into the Display. As traversal visits each scene node, the node's state core is + * set on the Display (such as {@link #flags}, {@link #layer}, {@link #renderer} etc), which we think of as the + * cores that are active at that instant during compilation. Each of the scene's leaf nodes is always + * a {@link SceneJS.Geometry}, and when traversal visits one of those it calls {@link #buildObject} to create an + * object in the soup. For each of the currently active cores, the object is given a {@link SceneJS_Chunk} + * containing the WebGL calls for rendering it.

+ * + *

The object also gets a shader (implemented by {@link SceneJS_Program}), taylored to render those state cores.

+ * + *

Limited re-compilation may also be done on portions of a scene that have been added or sufficiently modified. When + * traversal visits a {@link SceneJS.Geometry} for which an object already exists in the display, {@link #buildObject} + * may update the {@link SceneJS_Chunk}s on the object as required for any changes in the core soup since the + * last time the object was built. If differences among the cores require it, then {@link #buildObject} may also replace + * the object's {@link SceneJS_Program} in order to render the new core soup configuration.

+ * + *

So in summary, to each {@link SceneJS_Object} it builds, {@link #buildObject} creates a list of + * {@link SceneJS_Chunk}s to render the set of node state cores that are currently set on the {@link SceneJS_Display}. + * When {@link #buildObject} is re-building an existing object, it may replace one or more {@link SceneJS_Chunk}s + * for state cores that have changed from the last time the object was built or re-built.

+ + *

Object Destruction

+ *

Destruction of a scene graph branch simply involves a call to {@link #removeObject} for each {@link SceneJS.Geometry} + * in the branch.

+ * + *

Draw List

+ *

The draw list is actually comprised of two lists of state chunks: a "pick" list to render a pick buffer + * for colour-indexed GPU picking, along with a "draw" list for normal image rendering. The chunks in these lists + * are held in the state-sorted order of their objects in #_objectList, with runs of duplicate states removed.

+ * + *

After a scene update, we set a flag on the display to indicate the stage we will need to redo from. The pipeline is + * then lazy-redone on the next call to #render or #pick.
