Doug’s MATLAB Video Tutorials

November 6th, 2009

I like his slow, clear, methodical presentation with great visualizations. It is the first time I have deeply understood some of the volume visualization techniques we have.

• 1 of 9 Definitions for scalar and vector fields.
• 2 of 9 Examples of scalar and vector fields (temperature in a room vs air currents)
• 3 of 9 Displays scatter3 and slice plots.
• 4 of 9 Displays contourslice and isosurface.
• 5 of 9 Making a 3-d plot ‘pretty’ with lighting, shading, interpolation, etc…
• 6 of 9 Displays quiver3 and coneplot
• 7 of 9 Displays and explains streamplot and streamslice
• 8 of 9 Displays and explains streamtubes and streamribbons
• 9 of 9 Unifying example

   Hey Doug, sure enough a good topic. Is it possible to put all the codes together (starting from your video1/9), so one can play with the parameters and get more insights. My research requires 3D-vector field visualization (Medical Imaging) - Upon completion of all 9 videos, I’m happy to share how I currently do the visualizations and pick the matlab brains on improvements ;)

   Great tutorials. Can’t wait to see the rest!

   I am really enjoying this tutorial series.
   With part 3, things are really starting to get interesting and not so trivial, anyway the explanations are as crystal clear as always.
   Thank you Doug!

   @Luca,

   Thank you for the kind words. I can take little credit for this series. I set up the microphone, started the screen capture and left my office for an hour as Patrick recorded this. I did the post-production, but the essence of this presentation is all Patrick.

   -Thanks,
   Doug

   @vick,

   I am not sure what you mean by “Put all the codes together”. There is a unifying example that uses all these visualizations at the end of the series.

   Yeah Doug, that’s what i meant - looks like i gotta wait till the series ends. Why the tease Doug, just blow ‘em all out !!

   @Vick,

   Glad to hear you all are anxious to see these.

   It takes a while to make these videos, you all can watch them much faster than I can make them! :) Holding them back like this gives me a chance to make more. I *try* to be about a month ahead of you all so that if things get outta control, I still have videos ready!

   -Thanks,
   Doug

   1000 Thanks Doug,

   I have never understood those things before watching your great tutorial video!!!
   I really wish that my prof could explain things the way you did ;)

   I am one of your million loyal fan out there, so keep doing those tutorials.
   They are just so GREAT!

   best regards,
   nils

   @nils,

   Thanks you, I felt the same way until I saw this video. I only did the editing of it. Patrick was the talent behind this one.

    Hi Doug,

    Thank you for the wonderful videos. I have a question related to slice. How can I save the output of the slice command onto a 2D image?

    @sudar

    Short answer: streamslice

    Check out 7/9 of this series. It goes up Tuesday 11/24/09.

    Enjoy,
    Doug
