I would like to make evenly distributed point on mesh (like below figure)

I tried draw points on every gird point. But that points is not evenly distributed (top of the mesh, points is dense. end of the mesh, points is spars.

Is there any function or toolbox to make the evenly distributed points on 3d mesh?

Thanks Park.

Maybe the first note from What If #60 can help you out. It is about random point on a globe, but it should be possible to modify that.

Another possibility is first creating too much points, and then loop through them, removing all points that are too close to another point.

There are a couple of submissions at the file exchange that deals with this type of problem. Maybe one of them will be good enough for your needs. Look at:
