How to Remove a Vertex from a Mesh?

To remove a vertex from a mesh, you typically select the vertex and then use a delete function. There are often a couple of methods available depending on the software and the type of vertex you are removing.

Here are the primary ways to remove a vertex, based on common 3D modeling workflows:

Methods for Vertex Deletion

Based on the provided reference, you can remove a vertex using the following techniques:

1. Using the 'Delete Edge/Vertex' Command: This is a general method that removes the selected vertices and often cleans up the surrounding geometry (edges and faces) associated with them.
2. Using the Delete/Backspace Key: This method is often used for specific types of vertices and might result in a different geometric outcome compared to the command method.

Step-by-Step Guides

Here's how to perform these actions:

Method 1: Using the Edit Menu Command

This method ensures that the vertex and its connected geometry are handled by a dedicated tool.

1. Select the Vertices: Switch to vertex selection mode and select the specific vertices you wish to remove from your mesh.
2. Access the Command: Go to the mesh editing menu (often labeled "Edit Mesh" or similar).
3. Choose Delete: Select the "Delete Edge/Vertex" option.

Executing this command will remove the selected vertices and their associated edges and faces, potentially leaving a hole in the mesh or modifying the surrounding structure.

Method 2: Using the Delete or Backspace Key

This method is often quicker but might have specific conditions or results depending on the software. According to the reference, it is suitable for certain vertex types.

1. Select Specific Vertices: This method works best when you select vertices that are:
   • Located at a corner of the mesh structure.
   • Connected to two edges only.
2. Initiate Deletion: With the qualifying vertices selected, perform one of the following actions:
   • Press the Delete key on your keyboard.
   • Press the Backspace key on your keyboard.

Using the Delete or Backspace key on these specific types of vertices often removes the vertex and potentially collapses the two connected edges into a single edge, simplifying the mesh without necessarily creating a hole.

Choosing the appropriate method depends on your desired outcome and the specific requirements of the mesh geometry you are working with.
