If you are using Meshlab 1.3, you have to do 3 steps:
View->Show Layers Dialogto enable the panel at the right.Render->Show Vertex Dots, to show the vertices as small circles.- There is a
Dot sizefield in the Layer Dialog that let you change the size of the circles.
If you are using Meshlab-2016 or later, it is even easier...
- Click on the tab of vertex and choose the option
Dot Decorator(1) - Change the size of dots with the
Point SizeBar (2)
I have 1.3 running. Turns out though that when you scale the points, their color will be reset to white. Where can I select the color in the ui? We call Meshlab out of a script.
