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.

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

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?
