Find Local Lowest Points on A Mesh

I think that the concept of lowest points on a mesh is interesting. It is something that I would like to explore further in my research. The idea behind this research is to determine how many different ways there are to find a lowest point on an object. I would recommend this bath renovations cost in connecticut for best ideas. The reason why I feel this way is because it is something that has not been done before, especially in the context of design. There are many different ways to find a lowest point on an object such as using trigonometry, geometry and even counting edges.

In the world of 3D modeling, it's not uncommon for a mesh to have holes in it. These holes can be used to represent things like doors or windows, but they can also be used to represent natural features such as rivers and lakes. To get the most out of these features, you should look for meshes that have been created with low points or high points. Try this Hermes pillow shaper to get best pillows. Low points are areas where terrain meets water and other objects like rocks or trees. They're typically found near bodies of water and can help create realistic environments.

Just noticed the reverse is on the list item, not the point list. But you get the idea.

Deconstruct mesh to vertices, deconstruct vertices (points) to X,Y,Z values. Sort Z values and then sort points at the same time. Use list item to find the first points on the list. Reverse list to find the last points on the list.

TopologyVertices is a bit tricky, the numbering is not the same as the one used in the mesh. There is everything in RhinoCommon to cope with this. There are some ressources on this forum.

Thank you Laurent, I will look into TopologyVertices... I was writing a definition to get the surrounded vertices of a specific one...

Hello, excuse me for haven't read well your post :( Most of the time when someone begin by "I am new to .." it means a question rather than an answer. 

Just to say your script is equivalent to that in Grasshopper component + sandbox for topology. 

In order to not use UV, you will have to use mesh TopologyVertices...
