System Architecture >Modular design >Adapter Pattern - scene graph integration >Python binding
SIGGRAPH 2011 OSG-BOF – David d’Angelo
Field Container >Simple scene graph
SIGGRAPH 2011 OSG-BOF – David d’Angelo
Field Container >Simple AVANGO scene graph
SIGGRAPH 2011 OSG-BOF – David d’Angelo
Field Container >Simple AVANGO scene graph
>Fields can be connected >Field changes are automatically propagated SIGGRAPH 2011 OSG-BOF – David d’Angelo
Field Container >Component-based design >Generic interface with reflection support
>Duck Typing >“If it walks like a duck and quacks like a duck, I would call it a duck” >No need for inheritance relationship >Dynamic binding
>Distribution >Value of fields define the state of a container >Used directly for serialization and network distribution
SIGGRAPH 2011 OSG-BOF – David d’Angelo
Display Setup >Goal > Run the same application in different environments without code modifications
>Avango-Display encapsulates the environment specific funcationality > Each configuration is described once in a config file
>Supported environments > Desktop, Powerwall, L-Shaped displays, Curved panoramic displays, ...

Volume Classification using the Occlusion Spectrum
SIGGRAPH 2011 OSG-BOF – David d’Angelo
What is the Occlusion Spectrum >Goal
> Use of occlusion information to classify volumetric objects > Highlight structures not boundaries
>Ambient occlusion as classification metric > Encodes average contribution of the surrounding neighborhood to the visibility of every voxel in the volume
>Credits
> Correa et al. 2009
SIGGRAPH 2011 OSG-BOF – David d’Angelo
Volume Classification using the Occlusion Spectrum >Idea
> Classify volumetric data based on “Ambient Occlusion” of voxels > Classification is based on the distribution of intensities in the neighborhood around each grid point
>Goal > Classify and visualize structures such as domes or channel systems
