Vertex information can be difficult to read

[ita1024]

MeshLab2022.02-linux.AppImage on Linux: "get info" for a vertex displays the information with white on yellow, which can be difficult to read:

Open any point cloud and try to display the coordinates of a vertex on an area that is not in the shade. A black outline could make the text more readable.

You can always change the color of the points from shading options. Anyway, the best way to solve the problem is to allow user to change the text color of the info tool (setting it to black may cause visibility issues in other cases).

Video players have a good solution for the same problem (movie subtitles).

First of all, thanks a lot for meshlab, alemuntoni. Great job. But, let's say your workaround is not very user friendly; actually, there are two issues here:

• the text color will never be correct when viewing a textured mesh ; and it's not really an option to force untextured mesh when user is asking for face information.
• the vertices info will however overlap as soon as we're not viewing close enough to the face; even then, changing the point of view will result in unreadable information.

I've come here to the following hack:

• info text must be shadowed somehow
• info text must be considered as belonging a set of simultaneous texts, and the set shall avoid 2d geometric collisions in rendering

The result looks like:

Here, though the face is tiny and though the scene presents different colors, all vertex info is visible.
