|
|
||||||
|
The Shape Proximity operation calculates maximal of all possible distances between two shapes.
|
||||||
|
|
||||||
|
This is just a TUI functionality. The provided class
|
||||||
|
<pre>
|
||||||
|
geompy.ShapeProximity()
|
||||||
|
</pre>
|
||||||
|
has an interface to compute proximity value with default parameters
|
||||||
|
<pre>
|
||||||
|
p = geompy.ShapeProximity()
|
||||||
|
value = p.proximity(shape1, shape2)
|
||||||
|
</pre>
|
||||||
|
|
||||||
|
Moreover, it also provides the functionality to customize the calculation.
|
||||||
|
For example, compute coarse proximity value basing on the number of sampling points for each shape,
|
||||||
|
or compute the precise value as a refining operation after the coarse value calculation.
|
||||||
|
<pre>
|
||||||
|
p = geompy.ShapeProximity()
|
||||||
|
p.setShapes(shape1, shape2) # customize calculator with input shapes
|
||||||
|
p.setSampling(shape1, 100) # assign number of sample points for the first shape
|
||||||
|
p.setSampling(shape2, 25) # assign number of sample points for the second shape
|
||||||
|
coarse_proximity = p.coarseProximity() # rough proximity value basing on the shape sampling and tessellation
|
||||||
|
fine_proximity = p.preciseProximity() # more precise proximity value using exact shapes
|
||||||
|
</pre>
|
||||||
|
|
||||||
|
