Examples of com.jme3.math.Matrix3f.mult()

com.jme3.math.Matrix3f.mult()
mult multiplies this matrix by a given matrix. The result matrix is returned as a new object. If the given matrix is null, a null matrix is returned. @param mat the matrix to multiply this matrix by. @return the result matrix.

        // loading 'obmat' and inverting it makes us avoid errors in such cases

        if (objectHelper.isParent(skeletonOwnerOma, armatureObjectOMA)) {
            boneMatrixInModelSpace = globalBoneMatrix.mult(invertedObjectOwnerGlobalMatrix);
        } else {
            boneMatrixInModelSpace = invertedObjectOwnerGlobalMatrix.mult(globalBoneMatrix);
        }


        Matrix4f boneLocalMatrix = parent == null ? boneMatrixInModelSpace : parent.boneMatrixInModelSpace.invert().multLocal(boneMatrixInModelSpace);
