2 Before we begin Make sure you have installed so you can follow along in the lab section
3 Background Open-source, multi-platform parallel data analysis and visualization application Mature, feature-rich interface Good for general-purpose, rapid visualization Built upon the Visualization ToolKit (VTK) library Primary contributors: Kitware, Inc. Sandia National Laboratory Los Alamos National Laboratory Army Research Laboratory
4 Data Types Supports a wide variety of data types Structured grids uniform rectilinear, non-uniform rectilinear, and curvilinear Unstructured grids Polygonal data Images Multi-block AMR Time series support
5 Visualization Algorithms Supports a wide variety of visualization algorithms Isosurfaces Cutting planes Streamlines Glyphs Volume rendering Clipping Height maps
6 Special Features Supports derived variables New scalar / vector variables that are functions of existing variables in your data set Scriptable via Python Saves animations Can run in parallel / distributed mode for large data visualization
7 Data Formats Supports a wide variety of data formats VTK ( EnSight Plot3D Various polygonal formats Users can write data readers to extend support to other formats Conversion to the VTK format is straightforward
8 Data Formats VTK Simple Legacy Format ASCII or binary Supports all VTK grid types Easiest for data conversion Note: use VTK XML format for parallel I/O VTK simple legacy format (
9 Data Formatting Example Data set: 4x4x4 rectilinear grid with one scalar variable
10 Visualization Pipeline All processing operations (filters) produce data sets Can further process the result of every operation to build complex visualizations e.g. can extract a cutting plane, and apply glyphs (i.e. vector arrows) to the result Gives a plane of glyphs through your 3D volume
11 Demonstration WRF weather forecast data set Rectilinear grid Multiple scalar and vector variables Time series Can show: Clouds Wind Temperature

13 Test-Drive
14 Getting Started Download example data file RectGrid2.vtk Right-click, Save link as Open
15 Today we will: Create isosurfaces for a scalar variable Clip and slice the isosurfaces Use glyphs to display a vector field Use streamlines to show flow through a vector field Edit color maps Add slices to show variable values over a plane Adjust opacities of filters Add color legends Create volume rendering
