Box3D quaternion to Matrix3x3.

[Ronniko]

b3MakeMatrixFromQuat for rightHand matrix ?

[erincatto]

Yes, Box3D is right handed.

[ompadu]

any chance for a left handed option like cglm has? #define CGLM_FORCE_LEFT_HANDED

[erincatto]

Incredibly unlikely. I'm working in Unreal (left-handed) with Box3D and the simulation is a mirror. But it all works.

[ompadu]

hmm, maybe a wiki article mention on how to use box3d in LH system ?

[erincatto]

I actually do nothing to make it work. It just works. When I view a replay in the sample app, the world is mirrored.

Given: Right Hand: {x,y,z,w}
Convert: Left Hand: {z,y,x,-w}

Another write this
Quaternion ConvertSensorToUnreal(float x, float y, float z, float w) {

Quaternion output;
output.x = -y;
output.y = -x;
output.z = -z;
output.w = w;

return output;

}

AI get this
x, y, z, w convert to -x, z, y, w
