1.2.1 projectClusterSetObjID

|
|
|

|
Geometric analysis is at its core performed by this method.
|
||
|
|
We do three things in sequence:
|
||
|
|
First, we project a sample of points to a dual space in which we can represent
|
||
|
|
the Geometric Primitive we are looking for as a point.
|
||
|
|
Second, we now might have a lot of scattered points in dual space, since
|
||
|
|
objects won't be perfectly regular, so we cluster those and reduce them to a
|
||
|
|
single center, representing a single Shape.
|
||
|
|
Third, for each such shape the corresponding part of our Cloud is assigned
|
||
|
|
ObjectIDs.
|
||
|
|
|
||
|
|
Also, for each assigned point, a bit in the bitMask of our MMRCloud is set,
|
||
|
|
to prevent reassignment of this point.
