示例1: UpdateUi

{
// use assimp math data structures because they have Decompose()
// the decomposition algorithm is not very sophisticated - it basically extracts translation
// and row scaling factors and then converts the rest to a quaternion.
// question: what if the matrix is non-invertible? the algorithm then yields
// at least one scaling factor as zero, further results are undefined. We
// therefore catch this case by checking the determinant and inform the user
// that the results may be wrong.
