Constrained Point Cloud Editing
- From the Grid object, do Compute/UniformTiles.
- From the UniformTiles, do Compute/SingleTile.
- From the SingleTile, do Display/BoundingVolume (recommended).
Now a box will appear in the data set display.
Use the Alt-Cursor keys to move this box, or use the buttons in the
SingleTile object.
- From the SingleTile, do Compute/BoxOfInterest.
- Expand the HeightDots to expert level 5.
- Attach HeightDots RegionOfInterest Region Of Interest
to BoxOfInterest.region.
The rendering of the point cloud will be constrained to the selected box.
Note that using the Alt-Cursor hotkeys (or any other such settings of keyboard
shortcuts) will still work to move the box.
- Expand the MaskedLabels to expert level 4.
- Attach MaskedLabels constraint Bounding Box
to SingleTile.RegionOfInterest.
This setup is ready to go for editing points only within the selected box.
Adjust parameters and keyboard shortcuts as needed.
Lower the expert level of the involved objects after usage as it appears
convenient.
Save the visualization network for future reusage.
Features
- At Expert Level 1 the SingleTile provides
a comment text input, which is intended to store textual
information per editing tile, such as "This tile is at work",
"This tile is perfectly done", "This tile has strange issues" or
similar. This text will change when the active cell number is
modified.
To store this information persistently, attach the InputGrid
parameter of the UniformTiles object to any Grid object that
is bound to a file, preferably the same grid as the one carrying
the point cloud that is used for editing.
The module will store this editing information in a new Grid
with a name derived from the input grid.
-
The SingleTile can be used to steer the camera such that it
views all tiles from the same direction and distance.
For this functionality attach the Camera's
InputCamera parameter (at expert level 2)
to SingleTile.cellview and adjust the
SingleTile parameters
altitude, azimuth,
distance and heightInCell,
as those are determining the view point relative to the
currently selected tile.
-
The SingleTile object allows to store color information per
cell and provides this color as output parameter.
This is useful when e.g. displaying a BoundingVolume of
this single tile and attaching that one's color input to
this SingleTile.color output.
