Visualize a Vertex-Position of a mesh

Questions
1

Hi,

I often make meshes with ExtrudePolygon().

Then I want to change some verticies-positions of the created mesh.

Is there simple way or a helper so I can visualize the “vertexNumber” when I use

var positions = myMesh.getVerticesData(BABYLON.VertexBuffer.PositionKind)
for(var vertexNumber = 0; vertexNumber<positions.length/3; vertexNumber++) {
positions[vertexNumber*3+2] -= 500;
}

It is difficult to know what verties I have to manipulate when I do not know the index in positions

For Example, I want to manipulate this Vertex:

VertexPos

Thx

I think it would be better to use picking and gui to display the info related to the closest vertex.
