Method Details

decomposePrincipalMomentsOfInertia

boolean decomposePrincipalMomentsOfInertia(Mat44 storeRotation,
 Vec3 storeDiagonal)

Decompose the inertia tensor into a diagonal matrix and a right-handed rotation matrix. The properties are unaffected.

Parameters:

storeRotation - storage for the rotation matrix (not null, modified)

storeDiagonal - storage for the diagonal matrix (not null, modified)

Returns:

true if successful, otherwise false

getInertia

Mat44 getInertia()

Copy the inertia tensor. The properties are unaffected.

Returns:

a new matrix (in kilogram.meters squared)

getMass

float getMass()

Return the mass. The properties are unaffected.

Returns:

the mass (in kilograms, ≥0)
