Many graphical objects such as curves, surfaces etc. are approximated by a numerical mesh. With PointsVisible = TRUE, the points of this mesh become visible.

Details:
PointsVisible = TRUE/FALSE enables/disables the plotting of mesh and submesh points.
The mesh points react to the attributes PointSize and PointStyle. However, they do not react to the attribute PointColor. Typically, mesh points are painted in the same color used for the line objects defined by the mesh points.
PointsVisible cannot be animated.
Example 1
We plot the sine function on a rather coarse mesh using the PointsVisible default value FALSE:
f := plot::Function2d(sin(x), x = -PI .. PI, Mesh = 20):
plot(f):
We use PointsVisible = TRUE to make the mesh points visible:
f::PointsVisible := TRUE:
plot(f, PointSize = 2*unit::mm)
We enable adaptive plotting:
f::AdaptiveMesh := 2:
plot(f, PointSize = 2*unit::mm)
delete f:
