During our first lab, we were asked to calibrate the room, make rigid bodies, custom make our own rigid bodies, and import data from Motive to Unreal so our rigid bodies can affect the VR world.
Calibration and Rigid Body
Before the lab I finished watching the introductory videos on the software interface, how to set up the room, and calibrating the room. However, since there were a lot of information and the demo videos used an older version of Motive, it took the other students and I a little bit of time to familiarize ourselves with the new interface. And we also tried to remember what the “correct steps” are as well.
Luckily the calibration was pretty straight forward once we figure out where each of the panel icons do and what the workflow is.
Making rigid body was very easy and straight forward since all we had to do was select the “dots” on screen and right click and the software will automatically calculate all the information and generate a centroid.
Making Custom Rigid Body
I made a headband with 3 markers. Kat mentioned there was a project in the previous years that also created headband rigid body so that players can participate in a game/environment that’s similar to Snake (the game).
Another student added markers on a rope and we noticed that it wasn’t tracking correctly in Motive. We later learned that since we set it as “rigid body”, and the distance between markers on the rope will change, it doesn’t and won’t really work.
Motive + Unreal
The last part is to set up our rigid body in Motive so that the data can be sent to Unreal to interact with the objects there. Kat already set it up for us, so all we had to do was to set up the rigid body that we want to use and assign them correct IDs so that Unreal can get that data.
Thanks Che-Yu for taking the photos. I completely forgot to take pictures during lab session and his photos saved my documentation.
