Change Resolution¶
Group (Subgroup)¶
Sampling (Resolution)
Description¶
This Filter changes the Cell spacing/resolution based on inputs from the user. The values entered are the desired new resolutions (not multiples of the current resolution). The number of Cells in the volume will change when the resolution values are changed and thus the user should be cautious of generating "too many" Cells by entering very small values (i.e., very high resolution). Thus, this Filter will perform a down-sampling or up-sampling procedure.
A new grid of Cells is created and "overlaid" on the existing grid of Cells. There is currently no interpolation performed, rather the attributes of the old Cell that is closest to each new Cell's is assigned to that new Cell.
Note: Present Features may disappear when down-sampling to coarse resolutions. If Renumber Features is checked, the Filter will check if this is the case and resize the corresponding Feature Attribute Matrix to comply with any changes. Additionally, the Filter will renumber Features such that they remain contiguous.
Parameters¶
| Name | Type | Description |
|---|---|---|
| Resolution | float (3x) | The new resolution values (dx, dy, dz) |
| Renumber Features | bool | Whether the Features should be renumbered |
| Save as New Data Container | bool | Whether the new grid of Cells should replace the current Geometry or if a new Data Container should be created to hold it |
