dgp's Introduction

Digital Geometry Processing

资料

作业截图

作业1

作业1是在mesh上实现单源最短路径算法--dijkstra算法和最小生成树算法--prim算法, 没有做可视化, 所以没有图.

作业2

作业2是可视化平均曲率和高斯曲率

作业3

作业3是曲面去噪, 本来设计了一个误差, 根据误差去调整迭代次数, 但是不同曲面这个误差不太一样, 所以把迭代次数和高斯函数都作为可以调的参数.

下面两张图是基本的去噪效果, 感觉效果还是不错的

下面三张图展示的是不同参数对结果的影响. 去噪前:

去噪后:

修改参数后的效果:

最后两张图展示的是对较大噪声的去噪效果, 去噪前:

去噪后:

作业4

Tutte's embedding method

自己实现了LSCM, 下面分别是balls, bunny, Nefertiti_face的参数化结果

作业5

作业5是ARAP参数化, 因为原理还没完全搞明白, 所以写了好久. 下面分别是balls, bunny, Nefertiti_face的参数化结果

好久没写DGP的作业, 这段时间主要去复习考研和提升一些工程能力了. 回过头来看这个ARAP应该是还有bug, 效果不太对, 等以后再回来改改

作业6

作业6是ARAP deformation

自己用blender做的模型, 变形前:

变形后:

spot模型, 变形前:

变形后(迈步):
