Go WASM GL
This project aims to expose the WebGL2 API as Go API that can be used in wasm projects.
Warning: The project is in early development and the API is likely to change in backward incompatible ways!
Getting Started
You need to add the project as a dependency.
go get github.com/mokiat/wasmgl@latest
The implementation uses syscall/js calls and as such requires that client
applications are compiled with the GOOS=js and GOARCH=wasm options.
If you are unfamiliar with how Go and WASM works, then you should have a look at the official WebAssembly with Go documentation.
Following is an example Go code that clears the canvas with a green color.
package main
import (
"log"
"github.com/mokiat/wasmgl"
)
func main() {
const canvasElementID = "glcanvas"
if err := wasmgl.InitFromID(canvasElementID); err != nil {
log.Fatalf("Failed to initialize wasmgl: %v", err)
}
wasmgl.ClearColor(0.0, 1.0, 0.0, 1.0)
wasmgl.Clear(wasmgl.COLOR_BUFFER_BIT)
}
