Freepie Psmove is 180 degrees rotated

[tomazcdn]

Hello im with a big issue,im using psmove on freepie to make positional tracking on steamvr,but when i turn on it is rotating to 180 degrees back,i need to make the orientation of freepie 180 degrees to back on X axis to try solve my problem,so im using this code:

def update():
freeTrack.pitch = -freePieIO[0].pitch * math.cos(freePieIO[0].yaw/2) - freePieIO[0].roll * math.sin(freePieIO[0].yaw/2)
freeTrack.roll = - freePieIO[0].pitch * math.sin(freePieIO[0].yaw/2) + freePieIO[0].roll * math.cos(freePieIO[0].yaw/2)
freeTrack.yaw = freePieIO[0].yaw

#Multiply by 10 for SteamVR use
freeTrack.x = (freePieIO[0].x * 10)
freeTrack.y = (freePieIO[0].y * 10)
freeTrack.z = (freePieIO[0].z * 10)

if starting:
freePieIO[0].update += update

Here a video showing whats my issue (the psmove need to go front and view too,but its inverting the action,i mean my psmove go to front and my view to back)

if there is a audio on this video,please ignore or mute. Thank you very much,any help is very welcome

That's as simple as inverting (negating) the movement on the two horizontal axes (which are x and y, or x and z, I don't know what coordinate space these things use).

Thanks for the big tip,i will try to change it on freepie,but im not good on programming so im trying to manage how im going to invert it... i use *180 or * (-1) ?

[MarijnS95]

By adding a minus sign to the respective calculations, so that would be:

freeTrack.x = -freePieIO[0].x * 10
freeTrack.y = -freePieIO[0].y * 10
freeTrack.z = freePieIO[0].z * 10

or

freeTrack.x = -freePieIO[0].x * 10
freeTrack.y = freePieIO[0].y * 10
freeTrack.z = -freePieIO[0].z * 10

depending on the coordinate system.

hmm good idea... i did solve the problem just right now,it was on trinus gyre aplication,it says (use 0 instead of -1) so i let -1...but i will try your solution because my own isnt that good

[tomazcdn]

yeah your solution didnt worked..atleast not the - withot the (freepie...) i mean without " ( ) "
so i finished leting the problem solved on trinus gyre... the solution is: dont change the "rotIndex":-1,
thank you very much
