# hlg (High Level Graphics)
This project is a WIP. The goal is to make a high level graphics api for golang.
[](https://pkg.go.dev/github.com/dfirebaugh/hlg)
Documentation: https://dfirebaugh.github.io/hlg/
### Examples
check the `./examples` dir for some basic examples
#### Triangle
```golang
package main
import (
"github.com/dfirebaugh/hlg"
"golang.org/x/image/colornames"
)
var triangle hlg.Shape
// update operation need to happen less frequently than render operations
func update() {
}
func render() {
hlg.Clear(colornames.Skyblue)
triangle.Render()
}
func main() {
hlg.SetWindowSize(720, 480)
hlg.SetScreenSize(240, 160)
triangle = hlg.Triangle(0, 160, 120, 0, 240, 160, colornames.Orangered)
hlg.Run(update, render)
}
```
#### Colored Triangle
```golang
package main
import (
"github.com/dfirebaugh/hlg"
"golang.org/x/image/colornames"
)
var triangle hlg.Shape
const (
screenWidth = 240
screenHeight = 160
)
// update operations happen less frequently than render operations
func update() {
}
func render() {
hlg.Clear(colornames.Skyblue)
triangle.Render()
}
func main() {
hlg.SetWindowSize(screenWidth, screenHeight)
hlg.SetTitle("color triangle")
triangle = hlg.PolygonFromVertices(0, 0, 0, []hlg.Vertex{
{
Position: [3]float32{0, screenHeight, 0},
Color: colornames.Red,
},
{
Position: [3]float32{screenWidth / 2, 0, 0},
Color: colornames.Green,
},
{
Position: [3]float32{screenWidth, screenHeight, 0},
Color: colornames.Blue,
},
})
hlg.Run(update, render)
}
```
