MeshInspector rotation

[theElandor]

In MeshInspector when I try to rotate my mesh 180 degrees around a specific axis, it automatically clips the rotation to 90 degrees.
Am I missing something or is it a bug?

Hello!
Rotation in MeshInspector transform box is set in Euler angles, which might lead to "Gimbal lock". To avoid this we limit Y axis in [-90;90] degrees range.

To achieve 180 deg rotation on Y axis you can set X and Z axes to 180, and Y to 0

EDIT:
We cannot actually avoid gimbal lock, but this limitation allows us to convert data without degenerations:

MeshLib/source/MRMesh/MRMatrix3.h

Lines 241 to 250 in 0aadb8c

	template <typename T>
	constexpr Vector3<T> Matrix3<T>::toEulerAngles() const noexcept MR_REQUIRES_IF_SUPPORTED( std::is_floating_point_v<T> )
	{

	return {
	std::atan2( z.y, z.z ),
	std::atan2( -z.x, std::sqrt( z.y * z.y + z.z * z.z ) ),
	std::atan2( y.x, x.x )
	};
	}

Thanks!
