<div dir="ltr">Why do you need a vtkPoints? In the example it is only used to create the points. For a uniform grid (or image data) the points are not stored but infered from origin and spacing so you should not need them at least for making something similar
with the example work.

<p>Hi All,<br>
<br>
I am new to VTK and I have trouble visualising just the points of a "vtkUniformGrid". I create a grid and attach Scalars to its points. So far so good but when it comes to visualising the points of the grid im having problems.<br>
</p>
<p><br>
</p>
<p>I found "SetRepresentationToPoints"<wbr>sadly this only visualises the surface of my Grid but i want ALL points of the grid.</p>
<p>The next promising thing I found is "vtkVertexGlyphFilter" but I didnt manage to find a comfortable way of connecting my Grid to it , without creating "vtkPolyData" by iterating through all points of the grid one by one.</p>
<p><br>
</p>
I am pretty sure there must be an easy way to visualise a Grid as Points but im unable to find it.<br>
Any help is very much appreciated!<br>
<br>
