<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>
Greetings<span class="m_2936931388068564761m_7048434725104759329HOEnZb"><font color="#888888"><br>
