Where there values are +visible in the UI, the sign of y and angle values are changes to correspond to the more standard "+y up" and "+angle counterclockwise". For performance reasons, we change the sign by multiplying by -1, rather than using a `ModelViewTransform2`. ### Query Parameters -Query parameters are used to enable sim-specific features.
