Components are the parts of a geometric object such as points, edges, and polygons.

Individual components are referenced using an number called an index. For example, the following expression refers to the point at index number 3 on the cube "aCube":


Component indexes start at 0, so the first point is:


For this reason, it is easier to think of aCube.pnt[3] as point number 3 instead of as the fourth point.

Geometric components such as points are indexed from 0 to LAST.



What it indicates


Points 3, 6 and 8 on an object named "Cone"


Points 3 to 8 and 10


All the points on the object (equivalent to Cone.point[0-LAST])


The polygon


Points 1 to 3, 6, and the last point

Here's some examples for a nurbs surface:


What it indicates


Point (at u=2 and v=4)


Two points


An isopoint


A knot curve


An isoline


A boundary


A subsurface


A knot
