Real-time histogram presentation based on interactive volume rendered camera properties
Greetings -- Please forgive the subject line -- it makes sense to me; hopefully after reading the note it will make sense to me+1 or more.... Just last week I became aware of yt, and so this is a question about capabilities: I'm working on a project to aid a researcher with visualizing derived data products (a set of ~5000 histograms) along with volume rendering of simulations performed with Flash (flash.uchicago.edu). This would involve manipulation of the rendered volume data (e.g. temp, density data fields) and coordinated presentation in an inset or separate window from the set of histograms. The active camera view angles from the rendered volume display would be used to select from the histogram set (in this case indexed by 51 polar angle bins and 101 azimuthal angle bins). The key is for the histogram selection to take place as the rendered display is being updated through user interaction -- so as the view is rotated, the histogram updates without having to stop the user actions. Right now, these histograms are created at the end of the simulation. One could imagine a more general case in which the histogram were derived from the volumetric data in real time. Is this a task suited to the current state of yt development? Best regards, ~ Em -- ---------------------------------- E.M.

Hi Em, Thanks for writing. Right now, this isn't possible; I had delayed on writing back because I was experimenting with ways of augmenting the existing OpenGL VR to do this, but I ended up not coming up with anything in time. I absolutely think this is where we would like to go with our interactive VR, but I don't have a timetable for it right now. -Matt On Tue, Apr 11, 2017 at 9:54 AM, E.M.

If you'd be interested in experimenting with the OpenGL volume rendering, take a look at these doc pages: http://yt-project.org/docs/dev/visualizing/interactive_data_visualization.ht... http://yt-project.org/docs/dev/cookbook/complex_plots.html#cookbook-opengl-v... In addition, the place in the codebase to look to see how this is implemented is e.g. here: https://bitbucket.org/yt_analysis/yt/src/416bc87fd064d8cd5d64a98922c00c1cc71...

Hi Em, I think I have something that can get you going. If you could clone the following repository: hg clone https://bitbucket.org/xarthisius/reason cd reason hg update -C MPL_IDV and then run: python reason.py. It should create a simple Qt Widget with two frames: matplotlib canvas on the left, and yt's IDV on the right. Whenever you double click on the right panel it should update the left one with a current position of the camera. It should be possible to compute the angles you need from the camera's position and focus. All that's left is adding your data. This code, in addition to all dependencies of IDV, requires PyQt4 with OpenGL support. Let me know if there are any issues. Cheers, Kacper On 04/18/2017 03:27 PM, E.M. Dragowsky wrote:

I think that's a bug - there should be a cyglfw package in that channel. There were some changes to that channel recently so I guess that was dropped unintentionally. For now you will need to install cyglfw3 and glfw3 from source, I think. You should be able to do that using your conda setup using e.g. pip, although you'll need access to a compilation environment.

Just last week I became aware of yt, and so this is a question about capabilities:
I'm working on a project to aid a researcher with visualizing derived data products (a set of ~5000 histograms) along with volume rendering of simulations performed with Flash (flash.uchicago.edu). This would involve manipulation of the rendered volume data (e.g. temp, density data fields) and coordinated presentation in an inset or separate window from the set of histograms. The active camera view angles from the rendered volume display would be used to select from the histogram set (in this case indexed by 51 polar angle bins and 101 azimuthal angle bins).

Just last week I became aware of yt, and so this is a question about capabilities:
I'm working on a project to aid a researcher with visualizing derived data products (a set of ~5000 histograms) along with volume rendering of simulations performed with Flash (flash.uchicago.edu <http://flash.uchicago.edu/>). This would involve manipulation of the rendered volume data (e.g. temp, density data fields) and coordinated presentation in an inset or separate window from the set of histograms. The active camera view angles from the rendered volume display would be used to select from the histogram set (in this case indexed by 51 polar angle bins and 101 azimuthal angle bins). The key is for the histogram selection to take place as the rendered display is being updated through user interaction -- so as the view is rotated, the histogram updates without having to stop the user actions.
Right now, these histograms are created at the end of the simulation. One could imagine a more general case in which the histogram were derived from the volumetric data in real time.
Is this a task suited to the current state of yt development?
Best regards, ~ Em

I think this is happening because Kacper only made conda builds for python3.5, not python3.6. I *think* it will work if you downgrade python to python3.5, and set up your python environment once again. We should probably set up a conda-forge package for glfw and cyglfw3 so we can automatically take care of these package updates. -Nathan On Thu, Apr 20, 2017 at 4:05 PM, E.M.

Hi, Matt -- Thanks for offering this assessment of the current state, including the notion that my interest aligns with future plans.
To aid in my report back to my sponsors, perhaps I can extend this conversation to determine if there's anything I can contribute to this development effort? I've described myself as a "researcher who can code", definitely not to be confused with a practiced developer, and yet...these topics of volume rendering and coordinated views have become really interesting to me.
Please let me know, ~ Em

Hi Em,
Thanks for writing. Right now, this isn't possible; I had delayed on writing back because I was experimenting with ways
of
augmenting the existing OpenGL VR to do this, but I ended up
not
coming up with anything in time. I absolutely think this is where we would like to go with our interactive VR, but I don't have a timetable for it right now.

Greetings --
Please forgive the subject line -- it makes sense to me; hopefully after reading the note it will make sense to me+1 or more....
Just last week I became aware of yt, and so this is a question about capabilities:
I'm working on a project to aid a researcher with visualizing derived data products (a set of ~5000 histograms) along with volume rendering of simulations performed with Flash (flash.uchicago.edu <http://flash.uchicago.edu/>). This would involve manipulation of the rendered volume data (e.g. temp,
density
data fields) and coordinated presentation in an inset or separate window from the set of histograms. The active camera view angles from the rendered volume display would
be
used to select from the histogram set (in this case indexed by 51 polar angle bins and 101 azimuthal angle bins). The key is for the histogram selection to take place as the rendered display is being updated through user interaction -- so as the view is rotated, the histogram updates without having to stop the user actions.
Right now, these histograms are created at the end of the simulation. One could imagine a more general case in which the histogram were derived from the volumetric data in real time.
Is this a task suited to the current state of yt
development?
Best regards, ~ Em
