Aoyagi LabColloquium
Activity Data Renderer
2015-05-11 ~ Michele Bianchi
1.The problem
Taking a look at the problem and the proposed solution
The problemWe would like to represent in 3D datasets of human activity, understanding how the body
blocks radio waves during such activities.
Proposed Solution
Use an already available engine with skeletal mesh control to render the data and the body
coverage
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
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
2.Solution
The proposed solution and what has been done by now
InputDatasets 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
OutputActivity animation applied to a body skeleton.Using dynamic meshes we can render in real time the body coverage for each sensor node.
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
BlueprintNode Composing Scripting
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.
3.Future work
What I am doing, what I am planning to do for the project
Official TuorialsUE4 C++ Development
Future work
Control Skeleton through C++ (arbitrary)
Transform datafile in angle streams
Render body occlusion
Define a file structure for future uses
Thanks!Any questions?
