 == Overview ==
- This is intended to be a short task with no great visible result, though it's important to be done in order to prepare for an effective and efficient Scenes implementation.
+The goal of this task is to provide basic prototype implementations for Scene performance optimizations in two directions - algorithmic and hardware.
 
 == Task requirements ==
- * Finish SCENE_COMMONS_R1 by providing unit tests for it and fixing mistakes if any.
- * Research and compare different alternatives for improving Scenes' peformance:
+'''Algorithmic part:'''
+This part introduces new concepts in the Scenes abstraction and implementation like sprites, tiles, etc. Some smart algorithms will be used in order to make the future implementation faster.
+
+The new changes will include:
+ * Introduction of sprites and tiles,
+ * Integration of sprites and tiles with Scenes, SceneHelpers, SceneElements, etc.
+ * Introduction of a global cache for tiles,
+ * Introduction of some concrete effects like clipping and coloring, etc.
+ * and possibly others.
+
+The visible result for the algorithmic optimizations will be a demo which:
+ * creates a scene,
+ * adds some scene elements to it,
+ * possibly modifies them,
+ * the scene gets updated at each modification.
+
+This demo will be useful because it will show that the scene gets redrawn correctly with each modification of its model with the new concepts of sprites and tiles.
+
+'''Hardware part:'''
+
+ * Research and compare different alternatives for improving Scenes peformance:
   * Algorithmic optimizations. These ideas are described in http://asteasolutions.net/videos/2009-05-16,17-Discussions/2009-05-16-Discussion04%20-%20Scene%20Effects(bg%20audio).mpg
    * Sprites
    * Tiles
+
   * GL utilization
    * How to integrate a GL lib with the Scenes hierarchy?
