3D Model Editing from Contour Drawings on Orthographic Projection Views

3D modeling and mesh editing for objects from orthographic projections of engineering drawing has been very common and convenient. People has been accustomed to using such simple and fast sketching way to express their visualized thought. In this paper we present a method for model designers by sketching on the orthographic projection to control the deformation of surface meshes. Our system lets the user easily choose the region of interest for constraining the deformation area, and then sketch the desired contour. For a given new sketch on the orthographic projection, the system automatically deform the 3D model by using Laplacian deformation, which makes the contours of 3D model fit the contour line of the users sketching. Various examples have validated the effectiveness of our proposed method, which can be regarded as a effective method in 3D model editing.
