getStandardizedHpr LVecBase3f LVecBase3f::get_standardized_hpr(void) const; Description: Try to un-spin the hpr to a standard form. Like all standards, someone decides between many arbitrary posible standards. This function assumes that 0 and 360 are the same, as is 720 and -360. Also 180 and -180 are the same. Another example is -90 and 270. Each element will be in the range -180.0 to 179.99999. The original usage of this function is for human readable output. It doesn't work so well for asserting that foo_hpr is roughly equal to bar_hpr. Try using LQuaternionf::is_same_direction() for that.
