Summary:The invention discloses a comprehensive contour curve offset method. A contour curve is processed according to equidistant bias and non-equidistant bias, a 'curved skeleton' is derived on the basis ofa straight skeleton principle and used for simply and efficiently calculating the equidistant bias result of the contour curve, and the equidistant bias condition is processed through the steps of calculating a bisectrix, forming the curved skeleton, solving the bias result and the like. In addition, a new thought of a piecewise intersection offset solving algorithm is innovatively provided, so that the algorithm can be applied to solving of a non-equidistant offset problem; the non-equidistant bias condition is processed through the steps of local bias, extension intersection, cutting and splicing, self-intersection processing and the like. The method has the beneficial effects that the method can be applied to house type tools and whole house customization tools of a certain large online home decoration design
