Bulid  >> Merge >> Meshes >> Volume

• Bulid >> Merge >> Meshes >> Volume command merges two or more shells by calculating distance between node point of voxel and vertex.

Step   

Execute Bulid >> Merge >> Meshes >> Volume  command as follows:

1. Select Bulid >> Merge >> Meshes >> Volume  from the menu or click the corresponding icon from the Build toolbar.

2. Pick shell to merge and select Done on RMB menu, or select All on RMB menu to merge all the shell.

3. Following dialogue should be appeared. 

Resolution is ratio to average vertex spacing. If number larger than 1 is inputted. Face edge of merged shell is larger than selected shell. In other case, vise versa.

When user merge shells which can  be projected without intersection, IF user use Quick Projection option, merging speed can be improved.

If user selected Optimize Mesh option, rapidform makes a polygon' size regular

4. Input proper number and select OK to merge.

Polygonal edge of Volume Merge	Polygonal edge of Surface Merge

Note

• Voxel is 3D lattice having a uniform size internally.
• Compared surface merge, Memory occupation of Volume merge is little higher than Surface Merge
• If shells have a complicate boundary, Processing speed of Volume Merge is faster than that of Surface Merge. But, in case of simple shell, process takes more time than Surface Merge.
• In case of shell having complicated Boundaries or badly registered, Overlap region after merging is more smooth than Surface Merge.
• If coordinate  of shell is different with Local coordinate, There may be some holes in inclined region. This can be improved by Shell Transformation (see  Edit >> Transform >> Shell) before Volume Merge
• Polygon pattern after Volume merge can be removed by Global Remesh (see Tool >> Remesh >> Global)
• If user does this process on polygon shell with feafure region , Below warning message will appear.

  

• Vertex color is preserved during the operation
