An adaptive feature-preserving isotropic remesher

This is an implementation of modified classical isotropic remeshing algorithm in libigl.

How to build:

Use the files under src
Set 3rd party libraries(libigl and the external in it)

How to run:

A prebuilt demo is provided in exe, run it by specify the model:

remesher.exe ../data/cow_head.obj

How to use:

'Reset' firstly.
Set target length, mostly 0.02 (for cactus), 0.01 (for horse) or 0.005 (for cow_head)
Click 'Remesh' to do one iteration
Do at least 4 iterations
Similary, you can click 'adaptive', now only tried on cow_head (0.008 length)
