  4. 4. AVAILABLE TECHNOLOGIES AND NEEDS Task Large scale planning and decision making processes supported by interactive tool. Assumption ICT provides nowadays a large amount and typologies of tools which offer the possibility to visualize numerous data and relate them to specific features. Thus, in this research, no new software has been created. Existing software have been investigated in order to find the best fitting to multidisciplinary processes.InViTo: an interactive visualization tool for supporting planning processes Slide 4 / 27INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
  5. 5. AVAILABLE TECHNOLOGIES AND NEEDS What did I look for? A single tool to manage and display data and variables with the possibility of obtaining customized output graphs. Capability of relating choices and proposals to their effect on territory transformations and possibility of visualizing outputs in real-time in order to support workshops an focus groups. Construction of a replicable and easy fitting method.InViTo: an interactive visualization tool for supporting planning processes Slide 5 / 27INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
  6. 6. MC NEELS RHINOCEROS AND GRASSHOPPER Rhinoceros® (Rhino) is a stand-alone, commercial NURBS-based 3-D modeling tool, developed by Robert McNeel & Associates. The software is commonly used for industrial design and architecture. Grasshopper™ is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. Shapes are created using generative algorithms that can contain different types of input including numeric, textual, audio- visual applications. Usually Rhinoceros and its plug-in Grasshopper are used for industrial and architectural design at the building or HUNTERS POINT SOUTH HANGZHOU VESSEL CHAIR furniture scale.

  7. 7. WHY RHINOCEROS AND GRASSHOPPER? Generative: grasshopper plug-in allows to generate shapes without standard CAD environment modelling. Shapes are described by a sequence of processing steps. Parametric: mathematical functions and relationships among them define shapes and their behaviours. Dynamic: outputs change in real time according to user choices following the rules of assessment method. Easy to customize: using common scripting languages (Python, C# or VisualBasic).InViTo: an interactive visualization tool for supporting planning processes Slide 7 / 27INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
  8. 8. WHAT’S NEW WITH RHINO AND GH? Scale factor: a software, commonly used at building scale (or lower), are adapted to a large area planning process. GIS: potentiality offered by script codes are used to combine Grasshopper with ESRI GIS shapes and data. Assessment Methods: the dynamics of various assessment models such as multi-criteria analysis, surveys, conjoint analysis are reproduced in order to visualize outputs. Participatory Processes: the instrument represents a useful tool for participatory planning.InViTo: an interactive visualization tool for supporting planning processes Slide 8 / 27INPUT 2012 - Seventh International Conference on Informatics and Urban and Regional Planning – Cagliari 10-12 May 2012
