how can use gp3 create mesh faster?

[abstig]

I try to use gp3 to create a mesh form my slam pcd file,there are almost five million pointcloud,i use some filter to reduce my pointcloud,finally it have four million leave,but gp3 use time so long,near 19 min.So i want to know how to use gp3 to be faster?Here is my result.

Actually，there are some hole in my mesh file,i also want to know what paramter can change the problem.

Maybe try to use voxelfilter first, to reduce close points/high density areas.

You can read more in the tutorial: https://pcl.readthedocs.io/projects/tutorials/en/master/greedy_projection.html

Ie. use setSearchRadius to maybe close gaps.

Sorry for so late to reply!Actually,i used to try to use voxelfilter to reduce some points,but i found out it will make the hole more than without use it,so i decided to not use it,
