= Analysis =
== Overview ==
This task should improve the hardware part of the scenes implementation.
== Task requirements ==
 * Document the committed code in the second_resource_refactoring branch in some nice place.
 * Design and implement an efficient algorithm for performing scene effects in the JOGL implementation of the Scenes.
  * Implement 1-2 sample effects like shadow and blur if possible.
 * Try to fix the .so, .dll problems or at least propose how to deal with this problem.
 * Improve the SceneDemoTest to have effects.
  * Rename SceneDemoTest to a more clever thing (:
 * Coach meddle some JOGL (:
 * Add demos for JOGL usage.

== Task result ==
 * Working and demo-able scene effects in the JOGL implementation.
 * Improved and renamed SceneDemoTest with effects.
 * JOGLy enlightened meddle.
 * Documentation of the done work from previous revisions and this one also.

== Implementation idea ==
 * Use FBOs.
 * Use shaders.
 * Upload all buffers in FBOs in VRAM and manipulate them there.

[wiki:GROUP_SCENES_R1]

== How to demo ==
 * Show the improved SceneDemo with effects.
 * Run Sophie with some effects (this is mostly independent from this task because a runnable Sophie is other people's tasks (:)

= Design =
 * offscreen rendering
  * FBO
  * FBODemo
 * shaders
  * JoglShaderProgram
   * /resources/shaders
  * ShaderDemo
   * /resources/test-shaders

 * ElementHelpers refactoring:
  * getEffectiveVisibleArea
  * getEffectiveResponsibleArea
  
 * SceneEffects
  * ImmArea getVisibleArea(ImmArea sourceArea)
  * ImmArea getResponsibleArea(ImmArea sourceArea)
  * void applyTo(GL2 gl, ImmMatrix effectiveTransform)

 * Misc
  * SceneUtil -> JoglSceneUtil
  * GL2 instead of GLAutoDrawable

= Implementation =
^(Describe and link the implementation results here (from the wiki or the repository).)^

= Testing =
^(Place the testing results here.)^

= Comments =
 * what about PBOs and video? Uploading asynchronously the video to textures in VRAM could be much faster?
 * what about having two Scenes and the same TextureRegistry? Resizing one Scene will destroy texture bindings of the first scene?
