ink's Introduction

Ink is a framework for creative 2D graphics in Go, based on OpenGL. Visit buchanae.github.io/ink for more.

Example: a simple triangle

Install:

go get github.com/buchanae/ink

(Building Ink is a little tricky, because it depends on GLFW. You might need to install these packages:

build-essential
xorg-dev

Write example.go:

package main

import (
	. "github.com/buchanae/ink/color"
	. "github.com/buchanae/ink/dd"
	"github.com/buchanae/ink/gfx"
)

func Ink(doc gfx.Doc) {
	t := Triangle{
		XY{0.2, 0.2},
		XY{0.8, 0.2},
		XY{0.5, 0.8},
	}
	s := gfx.Fill{Shape: t}.Shader()
	s.Set("a_color", []RGBA{
		Red, Green, Blue,
	})
	s.Draw(doc)
}

Run:

ink example.go

Ink opens a window and renders your triangle:

There are more examples in the sketches directory.

Implementation Notes

Ink is based on OpenGL only, although other backends are desired. There is an experimental WebGL branch.
Ink is focused on 2D graphics, although 3D is desired some day.
Most numbers are float32, because OpenGL APIs are mostly based on float32s.
- This is also why I haven't used the Go stdlib image/color. I admit this feels messy.
Angles are in radians, unless otherwise noted.

No License?

Howdy, new Gopher here, excited to play around with Ink! But wondering what the license for it was & if we could get a formal license file in the repo?

Thanks and sorry if I missed something obvious!
