This way it is possible to subsample the cloud in a semi-gridded pattern. This option tells CloudCompare to keep in each grid cell the point from the input cloud which is the closest to the cell center (instead of the cell center itself). Note: interpolated scalar fields can only be used when exporting the raster grid as a new cloud or as a raster file in a formats that supports real-valued layers. by keeping the maximum SF value of all the points falling in this cell.by keeping the average SF value of all the points falling in this cell.by keeping the minimum SF value of all the points falling in this cell.To do this the user has to check the 'interpolate SF(s)' checkbox and define how this interpolation should be conducted: If the input cloud has one or several scalar fields, it is possible to 'interpolate' the scalar field values in each grid cell. Therefore a custom value must still be specified (in the field below the 'Fill with' drop-down list) to fill the remaining empty areas (if any). The biggest limitation is that it's limited to the convex hull of the non-empty cells. However it can be less realistic on big holes. This can give very good results in the presence of small holes. The 'interpolate' option consists in a linear interpolation with the nearest non-empty neighboring cells. use a user specified value (should be input in the field below the 'Fill with' drop-down list).use the maximum height of the whole grid.use the average height of the whole grid.use the minimum height of the whole grid.It is possible to fill these cells in various ways: They generally have a dedicated 'NaN' or 'empty' value when exported to a raster file (depending on the format). By default empty cells are not visible when displayed in the tool's 3D view.
If no point falls inside a given cell, this cell will be considered as 'empty'. The user has to click on it to actually apply the changes. Once the base parameters are properly set, the user must click on the 'Update grid' button to make CloudCompare actually compute the grid and display it.Įach time a parameter is modified, the 'Update grid' button will appear in red. the coordinate of the points along the projection dimension) but it can now be any scalar field associated to the selected cloud, the hillshade layer, etc. The default layer is 'height grid values' (i.e.
Dmesh zoom out update#
the grid step size ( CloudCompare will update the resulting grid size below so that the user can check that the grid is neither too big nor too small before actually generating the grid).The user must define the main (raster) grid generation parameters:
