Research Experience

Oct. 2015 –

Jan. 2016

Coarse to ﬁne fabrication of large object.

{

This project combines 3D printing and 2D laser cutting for cost-eﬀective fabrication of large

objects at lower cost and higher speed. Our key approach is to ﬁrst build coarse internal base

structures within the given 3D object using laser-cutting, and then attach thin 3D-printed parts,

as an external shell, onto the base to recover the ﬁne surface details.

{

I ﬁnished the code of model segmentation, namely, partition mesh into small fabricable parts

based on the inner polyhedrons and avoid obvious seams going through the important regions on

surface, and generate the connectors for assembling.

Mar. 2015 –

Jun. 2015

Support structure generation for 3D printing.

{

This is my undergraduate graduation design, I improved an existing algorithm of tree-like support

structure generation for 3D printing. The experimental results show advantages compared with

Cura and MeshMixer.

Aug. 2015 –

Sept. 2015

Fast color transfer from multiple images .

{

This project presents an eﬀective algorithm to transfer colors from multiple images to target image

by simple interaction, which combines color transfer and local linear embedding(LLE). And the

algorithm is accelerated by sampling the image.

{

I focused on writing the code of color transfer and local linear embedding, and also the paper

writing of algorithm.

Image & Geometry processing.

{

Skilled at Eigen library. Aware of common optimization methods, and can use Matlab Optimization

Toolbox, Ipopt, Ceres Solver skillfully.

{

Know the fundament of image processing. Implemented some image processing algorithms, like

color transfer, image warping, Poisson image editing, diﬀusion curves, etc.

{

Proﬁcient in halfedge data structure and OpenMesh library, and good at triangular mesh precessing.

Implemented some classical algorithm such as mesh parametrization, remeshing, surface smoothing,

ICP registration and so on.
