# GoPoints

A very simple Go library for creating shapes on a 2D plane out of points, using only the Go stdlib. Supports some basic functions like:

- storing points in a `Plane` structure

- joining arbitrary points with lines (including diagonal)

- filling shapes with points

- flipping the whole plane or some points along the X or Y axis

- fetching all points from a plane

- fetching points from a plane based on the return value (boolean) of a given function (like a mathematical equation)

- *TODO*: Applying an arbitrary transformation based on a function to the points on the plane

## Use cases

Can be used for any number of things, but my primary use-case is generating images made of 2D shapes, such as the [example image](https://github.com/TR-SLimey/gopoints/blob/master/examples/CreatePngImage.png?raw=true) generated with `examples/CreatePngImage.go`:
