# Tooltip pointing for 3D polyhedron vertices

How is possible to use Tooltip to point out vertices of a polyhedron? Would like coordinate display while mousing over the vertex. Thanks for the help.

Rohn = PolyhedronData["Icosidodecahedron", "VertexCoordinates"];
DelaunayMesh[Rohn]
Show[ListPlot3D[Rohn, AxesStyle -> Thickness[0.005],
AxesLabel -> {"X", "Y", "Corr(X,Y)"},
AxesEdge -> {{-1, -1}, {-1, -1}, {-1, -1}}],
ListPointPlot3D@
Tooltip@Flatten[MapIndexed[Flatten@{#2, #1} &, Rohn, {2}], 1]]


Using the method from this answer to a related question:

g3d = PolyhedronData["Icosidodecahedron"];
Graphics3D[{FaceForm[Opacity[.7]], g3d[[1]], {Sphere[#, .1] & /@ Rohn,
Tooltip[Text["", #], #] & /@ ToRadicals[Rohn]}}, Axes -> True,
AxesStyle -> Thickness[0.005], AxesLabel -> {"X", "Y", "Corr(X,Y)"},
AxesEdge -> {{-1, -1}, {-1, -1}, {-1, -1}}]


Do you mean something like this?

MeshRegion[DelaunayMesh[Rohn], MeshCellLabel ->
MapIndexed[Prepend[#2, 0] -> Placed[{#1}, Tooltip] &, Rohn]
]


• Yes, it helps a lot. Point update at places is slower however. Maybe thicker edge choice needed? – Narasimham Jun 17 '19 at 17:17
• What do you mean by "point update"? For thicker edges I would add MeshCellStyle -> {1 -> Thick} to MeshRegion. – ccosm Jun 17 '19 at 18:17
