fillPolygon is a function that is part of gc.

Fills the polygon defined by the lines connecting the (x,y) points.

The polygon is not automatically closed; the first x-y coordinate pair must be repeated at the end of the array of points to draw a closed polygon.


This has been introduced in TI-Nspire OS 3.0 (Changes).

Syntax

gc:fillPolygon({x(1), y(2), ..., x(n), y(n)})

Parameter Type Description
x(1)
number x-coordinate of the first point
y(2)
number y-coordinate of the first point
...
numbers x and y coordinates...
x(n)
number x-coordinate of the nth point
y(n)
number y-coordinate of the nth point

Example

gc:fillPolygon({0,0, 0,100, 100,100, 100,0, 0,0})

This draws a filled-rectangle (square, actually) whose points are at the given coordinates.
