| Display points | Glyph filter -> Spheres |
|
| Display lines as cylinders instead of raster lines | Tube filter |
|
| Triangulate a set of points (form a mesh) | Delaunay Filters |
|
| Downsample a point set | Quadric clustering |
|
| Measure the distance between two points | Sources -> Ruler | Hover over the first point then press 'p'. Then hover over the second point and press 'p' again. The distance is displayed in the Properties tab of the Object Inspector.
|
| Downsample a point set | Quadric clustering or Clean |
|
| A filter cannot be applied to a data set that it should work on | Run "Extract Surface" first. This has nothing to do with a surface, it simply converts an unstructured grid to a polygonal mesh so that it is the correct data type for the filter you are trying to use. |
