How can I increase the point size in Meshlab for point clouds? I found how I can show / hide specific PCs, but I do not see where to change their display properties : size, color, symbol ...

If you are using Meshlab 1.3, you have to do 3 steps:

  • View->Show Layers Dialog to enable the panel at the right.
  • Render->Show Vertex Dots, to show the vertices as small circles.
  • There is a Dot size field in the Layer Dialog that let you change the size of the circles.

MeshLab 1.3.2

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 Size Bar (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. – El Dude Dec 23 '19 at 19:39

In MeshLab, you can just use Alt + mouse wheel to control point size.

Or you can find the point size setting in:
Tools->Options->MeshLab::Appearance::pointSize.
