MEASURING ERROR BETWEEN SIMILAR SURFACES

Abstract

This paper suggests that the measurement of error between mesh surfaces that are similar can be performed more time-efficiently than the existing methods offer. We presume that evaluation of error between similar surfaces does not require so many sample points and two-way distance measurement. Also we apply a different technique for sample point picking that involves barycentric coordinates. Tests versus other methods show that our method performs faster in cases of identical and similar surfaces, but also produces a less precise result. Thus, it is considered to be effective in applications that do not need precise measurements, like fast detection of flaws, defor-mation or overlapping areas.
