Process and analyze surfaces using open3d and vedo in napari
Project description
napari-process-points-and-surfaces (nppas)
Process and analyze surfaces using open3d and vedo in napari.
Usage
You find a couple of surface generation, smoothing and analysis functions in the menu Tools > Surfaces
and Tools > Points
. For detailed explanation of the underlying algorithms, please refer to the open3d documentation.
Some code snippets and the knot example data have been taken from the open3d project which is
MIT licensed
and from the vedo documentation
which is MIT licensed.
The Standford Bunny example dataset has been taken from the The Stanford 3D Scanning Repository.
For processing meshes in Python scripts, see the demo notebook. There you also learn how this screenshot is made:
For performing quantitative measurements of meshes in Python scripts, see the demo notebook. There you also learn how this screenshot is made:
Surface measurements and annotations
Using the menu Tools > Measurement > Surface quality table (vedo, nppas)
you can derived quantiative measurements of
the vertices in a given surface layer.
To differentiate regions when analyzing those measurements it is recommended to use the menu Tools > Surfaces > Annotate surface manually (nppas)
after measurements have been made. This tool allows you to draw annotation label values on the surface.
It is recommended to do activate a colorful colormap such as hsv
before starting to draw annotations.
Furthermore, set the maximum of the contrast limit range to the number of regions you want to annotate + 1.
Annotations can be drawn as freehand lines and circles.
After measurements and annotations were done, you can save the annotation in the same measurement table using the menu
Tools > Measurement > Surface quality/annotation to table (nppas)
Measurement visualization
To visualize measurements on the surface, just double-click on the table column headers. This also allows to visualize measurements and annotations side-by-side.
