iMRV Tutorials

These tutorials apply to the Mac OS X version of the iMRV application. However, the Ubuntu version works identically but has a slightly different appearance. I am using Mac because QuickTime viewer has a built-in screen and audio capture utility.... very nice!

I haven't figured out how to get the movie player properly embedded in this web page, so just download the movies, save them, and double-click them; that should launch your favorite player. I like QuickTime.
Tutorial #1 (21 MB). This tutorial describes how to launch iMRV, read a SAM grid file, and generate an isosurface from one of the SAM grids. (Re-recorded 27Feb10 to be consistent with the current launch behavior of iMRV, and to descibe how to clip the domain to explore just the feature of interest!)
Tutorial #2 (14 MB). This tutorial shows how to manipulate the properties of the isosurface itself, and how to change the resolution of the underlying grid to see more or less detail.
Tutorial #3 (28 MB). The basics of how to select what is being viewed, rotation, panning, zooming, and axis properties are covered in this one.
Tutorial #4 (32 MB). How to generate contour plots and change their properties. I left something out of this. The best way to declutter the labeling is to use the property called Label Spacing. For some reason it is grayed-out in the latest version; this needs to be fixed.
Tutorial #5 (19 MB). The basics of how to use operations, and the Generate Reflectivity operation. I didn't mention in the tutorial that Operations are basically everything you can do to underlying data. Some operations will automatically operate on data you have selected in the visualization itself; some are more generic and go out and look for the appropriate data. The reflectivity operation is in this latter category. And a final point... when an operation is complete, any associated visualizations are automatically updated.
Tutorial #6 (18 MB). Computation of the Velocity vector grid from scalar component grids, and how to create a vector visualization and adjust its properties.
Tutorial #7 (40 MB). Computation of the Vorticity vector grid from the velocity vector grid (or more generally, the curl of any vector grid), and how to visualize the components and the vorticity vector.
Tutorial #8 (17 MB). Plotting of field lines. I started the tutorial by explaining what a field line is. I failed to give examples... field lines of a velocity field are streamlines, and field lines of a vorticity field are vortex lines. I encourage you to experiment with the seed patch shape, size, and number of lines. This visualization is clunky, to say the least, but you can probably get some real research done with it even in this state.
Tutorial #9 (12 MB). Axes. How to turn them on, hide them, label them, etc. There are a lot of user-settable properties for each axis, and I'll let you explore these properties to get the axis appearance you like. Note that the values on the axis are the original grid coordinates; the visualization in this tutorial has been clipped using the tool described in Tutorial #1.
