Tools Menu • Interactive tools for operating on volume 4
Mask Filters Menu • Operations on label masks 5
Data Filters Menu • Simple operations on layers (data or mask) 6
Advanced Filters Menu • Filters implementing complex algorithms 7
Architecture of Seg3D: Project Folders Example of a project directory Data files used in the sessions. Each volume is only stored once and masks are grouped together into one nrrd file Database files Provenance requires play back hence a copy is made of all the files that are imported, so all information is stored (GLP) Main project file (XML format) Each session is listed as its own file http://www.numirabio.com 8
Architecture of Seg3D: Layered Approach User Interface Layer (namespace Seg3D): Main Window, Menus, Tool Interfaces, Dialogs QtUtils ( namespace QtUtils) Custom Widgets, Link to StateEngine, OpenGL Linkage Lower layers do not depend Application Logic Layer (namespace Seg3D) on code in layers above: Application Logic, Filters, Layers, LayerManager, Tools, Importers/Exporters, Slice/Scene renderer Hence you could build a headless Seg3D version by Core Logic Layer ( namespace Core) taking the top layer off. Cleaned up classes from SCIRun (Geometry/Math/String Utilities), Data Volumes, State Management, Action Management, Core Renderer, Textures/Shader containers Externals: 3rd party libraries boost : threads, callbacks,lambda, signals/slots, sockets, filenames, file I/O itk : filters, image file format, teem : nrrd format, resampling gdcm : custom-dicom support, libpng/zlib/MatlabIO/hdf5 : image file format tinyxml : XML support, sqlite : provenance database glew : OpenGL bindings, freetype : OpenGL text rendering python : Built-in python interpreter http://www.numirabio.com 9
Architecture of Seg3D: Directory Structure Application Layer Standalone code for generating code on the fly, e.g. shaders Extensions to the CMake system and config files for CPack Templates for code that is automatically generated, e.g. plugins, version information Core Layer Documentation (slides) Third party Libraries Interface Layer Main program that starts the interface layer Plugins: Code in the sub directories of this one will be automatically included in the CMake system. Custom Qt Widgets Images/Icons used by the visual interface http://www.numirabio.com 10
