1. Aoyagi Lab
Colloquium
Activity Data Renderer
2015-05-11 ~ Michele Bianchi

2. 1.
The problem
Taking a look at
the problem
and the
proposed
solution

3. The problem
We would like to represent in 3D datasets of
human activity, understanding how the body
blocks radio waves during such activities.

4. Proposed
Solution
Use an already available engine with skeletal
mesh control to render the data and the body
coverage

5. Unity3D 5
Famous between
indie game
developers for its
ease of use.
Skeletal mesh
control capabilities
and scriptable
using C# and
JavaScript.
The engine itself is
not Open Source
but the script files
for projects can be
Open Source

6. Unreal Engine 4
Last version of a
very famous
engine in the
Industry.
Skeletal mesh
control using C++
and Blueprint.
The engine is Open
Source (github), so
all the project can
be Open Source

7. 2.
Solution
The proposed
solution and
what has been
done by now

8. Input
Datasets representing
the distances between
different articulations
(e.g. shoulder to wrist,
hip to ankle) per time
frame.
We can convert these
distances in angles for
each in-between
articulations.
Input and output of the program
Output
Activity animation
applied to a body
skeleton.
Using dynamic meshes
we can render in real
time the body
coverage for each
sensor node.

9. How does UE4 with skeletal mesh work?
Integrating a skeleton
definition, a skeletal mesh
and an animation blueprint
it is possible to control each
“bone” of the skeleton

10. Blueprint
Node Composing Sc

11. Problem
Started working on the
control of a skeletal mesh
by directly modifying the
skeletal nodes using a
Blueprint animation.
What works on an animated
mesh added by the wizard is
not working on a mesh
without animation.

12. 3.
Future work
What I am
doing, what I
am planning to
do for the
project

13. Official Tuori
UE4 C++ Developme

14. Future work
Control Skeleton through C++ (arbitrary)
Transform datafile in angle streams
Render body occlusion
Define a file structure for future uses

15. Thanks!
Any questions?

16. SlidesCarnival icons are editable shapes.
This means that you can:
● Resize them without losing
quality.
● Change fill color and opacity.
● Change line color, width and
style.
Isn’t that nice? :)
