  1. Annot3D Visualization Annotation Exploration Tool For Visualization, Annotation, and Exploration of Three Dimensional Datasets Annot3D Janna Balling Scientific Computing and Imaging Institute and Department of Bioengineering

  2. Problem • Anatomy Teacher’s Tool: • Visualize Original 3D CT datasets • Add annotations • Interact with model in real-time • Existing Tools: • only one, not all This is the Scapula

  3. This is the Scapula Pick the box to hide the Scapula User Anatomy teacher View Rendered Scene ??? global env global IDname set IDname $env(ClientID) set renderer Renderer set renderer $IDname$renderer set source DotSource set source $name$source set mapper DotMapper set mapper $IDname$name$mapper set actor Actor set actor $IDname$name$actor vtkPolyDataMapper $mapper $mapper SetInput [$source GetOutput] vtkActor $actor $actor SetMapper $mapper $actor SetOrigin 0 0 0 $actor SetPosition $x $y $z [$actor GetProperty] SetColor $r $g $b [$actor GetProperty] SetOpacity $opacity $renderer AddActor $actor set renderObjects RenderObjects set renderObjects $IDname$renderObjects lappend env($renderObjects) $mapper $actor Get Instructions ???

  5. (36.9698, 158.439, 45.2718) Features • CT Scan Datasets • VTK , raw, and Dicom formats • Annotations • shapes • highlights • buttons • screen coordinates • clipping • Interactions • rotate, translate, and zoom • pick objects • save 2D picture

  6. User Feedback Significantly more effective than printed atlases and textbooks in terms of helping students to gain a mind’s eye view and learn spatial relationships. “It adds quizzing abilities and multiple views which books don’t do.” “I wish I had had this for review on my anatomy exams.” “I would have loved to have [Annot3D] last semester.” from Anatomy Students
