Btw, I am a bit confused that why after applying a "2D Glyph" filter and "Glyph Type" as "Vertex", the number of points decreases. For example, if after applying "TableToPoints" filter I have 1 cell and 100k points, I get 502 cells and 502 points after applying a "2D Glyph" filter. I was expecting the number of cells to increase but total number of points should have remained 100k, no?
I am not really sure if applying a 2D Glyph is the best solution in my case. I may go back to using 4.0.1 to convert this csv data into pvtu and then use the latest version to load it up.
