vector minpos(<geometry>geometry, vector point)
Returns the position of the closest point in the given geometry to the point.
vector minpos(<geometry>geometry, vector point, float maxdist)
Returns the position of the closest point in the given geometry to the point, within the maxdist radius.
vector minpos(<geometry>geometry, string primgroup, vector point)
Returns the position of the closest point in the given geometry to the point, limiting the search to primitives in the named group.
vector minpos(<geometry>geometry, string primgroup, vector point, float maxdist)
Returns the position of the closest point in the given geometry to the point, limiting the search to primitives in the named group and to the maxdist radius.
<geometry>
When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.
Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo) to read from. When running inside Houdini, this can be an op:/path/to/sop reference.
primgroup
If specified, only report points on
You can also use group specification syntax like @Cd.x>0,
but note that the @ may need to be escaped with a backslash in a Wrangle snippet.
An empty string matches all primitives.
point
The point in world space to start looking for the closest point on the geometry.
maxdist
The maximum distance to search. Specifying this can speed up the function since it may allow quitting the search early.
Returns
The position of the nearest point on the geometry, or point if no nearest point was found.
