Sensor filtering and animated surface shading in Dasher 360 – Through the Interface

We’ve been busy working on a number of interesting features for
Dasher 360
over the last few weeks. The main focus – at least from my side
– has been to extend the filtering capability to allow people
to filter sensors based on type and their location in the
model. Not only that, but the filtering is reflected in
realtime in the list of sensors, even when highlighting
different areas of the model via the site’s breadcrumbs. I
wasn’t sure if this was going to be viable – mainly for
performance reasons – but for now it seems to work really well.

The other big push has been around surface shading and getting
that properly integrated into the timeline. The timeline is now
visible in the public demo and can be used to control the
period for which the surface shading gets animated. Eventually
the timeline will drive other visualizations, too, whether the
plots for individual sensors or for coordinated video feeds
(more on this below).

I recorded a quick video to show the progress:

 

 

These changes are only partially live on the main site, today,
but they’ll be there by the time most people read this post,
I’m sure. 🙂

In the above demo I’ve mentioned a feature that was implemented
for the Pier 9 bridge project: the ability to display video
from various cameras and have that correlate with surface
shading information. This is particularly interesting in the
context of the bridge, where we want to analyse strain data
while understanding the specific context: how many people were
walking over it, were they marching in military formation, that
kind of thing. At some point we expect to integrated machine
learning to analyse the image data and surface clues about
what’s going on, for now we’re just focused on getting the
video feeds sync’ed with surface shading.
