Defines a shape for a Pathfinding.GraphUpdateObject.
The shape consists of a number of points which it can either calculate the convex hull of or use as a polygon directly.
A shape is essentially a 2D shape however it can be rotated arbitrarily. When a matrix and a list of points is specified in the constructor the matrix decides what direction is the 'up' direction. When checking if a point is contained in the shape, the point will be projected down on a plane where the 'up' direction is the normal and then it will check if the shape contains the point.

Construct a shape.
points  Contour of the shape in local space with respect to the matrix (i.e the shape should be in the XZ plane, the Y coordinate will only affect the bounds) 
convex  If true, the convex hull of the points will be calculated. 
matrix  local to world space matrix for the points. The matrix determines the up direction of the shape. 
minimumHeight  If the points would be in the XZ plane only, the shape would not have a height and then it might not include any points inside it (as testing for inclusion is done in 3D space when updating graphs). This ensures that the shape has at least the minimum height (in the up direction that the matrix specifies).

getset 
Sets if the convex hull of the points should be calculated.
Convex hulls are faster but nonconvex hulls can be used to specify more complicated shapes.

getset 
Gets or sets the points of the polygon in the shape.
These points should be specified in clockwise order. Will automatically calculate the convex hull if convex is set to true
