Macros  
#define  ASSERT_ISOMETRY(transform) 
Assert that the given transform is an isometry. More...  
#define  CHECK_ISOMETRY_PRECISION Eigen::NumTraits<double>::dummy_precision() 
This file provides functions and macros that can be used to verify that an Eigen::Isometry3d is really an isometry. Eigen itself doesn't do the checks because they're expensive. If the isometry object is constructed in a wrong way (e.g. from an AngleAxisd with nonunit axis), it can represent a nonisometry. But some methods in the Isometry3d class perform isometryspecific operations which return wrong results when called on a nonisometry. E.g. for isometries, .linear() and .rotation() should be the same, but for nonisometries, the result of .linear() contains also the scaling factor, whether .rotation() is only the rotation part.

These checks are primarily meant to be performed only in debug mode (via the ASSERT_ISOMETRY macro), but you can call checkIsometry() even in release mode. This check should be mainly performed on transforms input by the user.The default precision to which the transform has to correspond to an isometry.

inline 
Check whether the given transform is really (mathematically) an isometry.
transform  The possibly nonisometric transform. 
precision  Precision to which the transform has to correspond to an isometry (elementwise). 
printError  Whether an error should be printed to std::cerr with details about the false isometry.
