Detailed Description

Provides methods for efficiently finding the closest point on
the surface of a mesh. An octree algorithm is used to find the
closest point.

Constructor & Destructor Documentation

def OpenMaya.MMeshIntersector.__init__

(

)

Initialize self.  See help(type(self)) for accurate signature.

Member Function Documentation

def OpenMaya.MMeshIntersector.__new__ ( )

static

Create and return a new object.  See help(type) for accurate signature.

def OpenMaya.MMeshIntersector.create

(

)

create(mesh, matrix) -> self

Creates the internal data required by the intersector. It is a
compute-heavy operation and should only be called when necessary.

mesh (MObject)   - the mesh to be used
matrix (MMatrix) - transformation to use to bring points into the
mesh's object space.faceIds (list) - the faces of the mesh to be passed to the intersector

def OpenMaya.MMeshIntersector.getClosestPoint

(

)

getClosestPoint(referencePoint, maxDistance=sys.float_info.max) -> MPointOnMesh

Finds the closest point within 'maxDistance' of the reference point
(MPoint) which lies on the surface of the mesh. The reference point
will first be transformed by the matrix passed in the create() call,
so if, for example, you want to specify reference points in world
space then the matrix passed to create() should provide the mapping
from world space to the mesh's object space.

Returns an MPointOnMesh object if a closest point is found, or None
if no closest point is found (e.g. referencePoint is not within
maxDistance of the mesh).

Raises ValueError if create() has not yet been called for this
intersector.

Property Documentation

OpenMaya.MMeshIntersector.isCreated = property(...)

static

 True if the intersector has been created, False otherwise.
