Vizualization Pipeline Study

[isolin]

Please read and study about the visualization pipeline with some additional explanations. Moreover, you should also study the rendering pipeline from the WegGL books (since the rendering step is important for you as well).

Assign your thesis tasks listed in the wiki to the steps in both pipelines, describe shortly what operations are performed. Write your results into the wiki for now, you will later just copy them into the thesis.

It might be that a single task requires actions in several steps. There might be several iterations or parallel runs of the pipelines required.

E.g. for defocus:

• Visualization
• Analysis = The input data is connected to a hierarchical structure of shapes
• Filtering = Picking by mouse
• Mapping = Distance to the next selected shape is computed
• Rendering
• 1st pass fragment shader - rendering to a texture + alpha channel indicates the blur strength
• 2nd pass - only a single full-screen quad with texture from pass 1 mapped, blur applied
