Legibility Graph

Extension of LOD notion

Context• Inputs

– 3D scenes– Different attributes for each object– Different rendering styles

• Problems– Simultaneous visualization– Online selection– Legible style superposition

• Main application– Archaeology

Examples

• Archaeology– Interpreted vs. Measured– Age– Usage– ...

• Volume rendering– cf SIGGRAPH course note 2003 - 23

• 2 styles:– Color & level of brown + line density

• Information: – Depth & characters

• LOD: – Light intensity

• 2 styles:– Color & hatching

• Information: – Depth & painting

• LOD: – Hatching density

• 2 styles:– Color & characteristic lines

• Information: – Depth

• LOD: – Intensity & Line density

Legibility Graph

• Node = Style– Input: style parameters– LOD notion

• Arc = Legibility relation– Extension of standard LOD– Context dependant– Juxtaposition and/or combination

Example

MIRO Goals

• Platform– Validation– Common code

• Validation– Set of data– Set of styles

Planning de travail

• 2 Stages: – 2005 et 2006

• 2005 : Objectifs– Précision des scénarios d’application

• Ausonius / LSC / Digisens

– Mise en place de la plateforme– Expérimentation

• 1er jeu de données• Nombre de styles réduits ( 4)

Planning de travail

• 2006 : Objectifs– Extension de la plateforme– Expérimentation

• Les nouveaux styles développés• Jeux de données complexes

– Validation sur les scénarios d’applications

Framework creation

● Summer Intership (Diego Berndt)● Results

– Definition of the Scene graph structure– Implementation of 2 rendering styles

● Toon shading● Fast silouhette

– Possibility of on-line selection of style and combination

Needs to be done

● Legibility graph● Integration to Magellan● Integration of Melik / Audrey work in the

framework● Atmospheric effect

NPR for Archeology

● Summer internship Melik● Results

– Stylized rendering of lines

– Combination with shadings

– Archaeological models ?

● Needs to be done– More models and bug correction

– Faster Rendering !!!!!!!

– Real line definition and not only segments
