Point and Polygon
data types have been given their own set of data members and methods.
In each case, additional information is available through these interfaces
that cannot be accessed by any other means in LScript.
Point and Polygon
messages are legal only during a mesh edit session (i.e., between calls
to editBegin() and editEnd()).
Point
The Point data type responds to the following messages:
polygon/polygon()
The polygon/polygon() element of the Point data type is overloaded to return
different data based on the context. If the element is accessed directly
(as a Data Member), then the number of polygons to which the point belongs
is returned. If the method context is invoked, then one or more polygon
identifiers will be returned to the caller. If the point is unassociated
with any polygon, the data member context will return zero (0), and the
method context will return 'nil'. The data member context is read-only.
x,
y, z
The x, y, z values hold the position of the point along the indicated
axis. These values can be read—they can alter the point position through
assignment.
Polygons
The Polygon data type responds to the following messages:
surface
surface is the surface name currently assigned to the polygon. This data
member can be read, and it can be assigned. If the surface name assigned
does not exist, LScript will first create it.
pointCount
pointCount is an integer value that contains the number of points that
comprise the polygon. This data member is read-only.
layer
layer is an integer value that indicates the Modeler layer in which the
polygon lives. This data member is read-only.
points[
]
points[] is an array of Point identifiers that contain all the points that
comprise the polygon. It has 'pointCount' elements. The elements in this
data member are read-only.
isCurve()
isCurve() returns a true or false value that indicates whether the polygon
is a curve (true) or a face (false).
hasCCEnd()
When the polygon is a curve, the hasCCEnd() method will return true
if it contains a control point at its tail.
hasCCStart()
When the polygon is a curve, the hasCCStart() method will return true if
it contains a control point at its head.
setPoints()
The setPoints() method can set the points that comprise the polygon. It
accepts an array reference containing pre-existing point ids, a list of
pre-existing pointer ids, or a series of one or more vector values that
the method will first convert into points and then apply to the polygon.
