Wrapper for OpenGL and WebGL in a single interface.

This project is based on the work from UnitofTime's Glitch internals.

Caveats

This project attempts to provide as close an interface as possible to go-gl/gl and go-gl/glfw while being compatible with both Desktop and Web runtimes.

  • By design, these interfaces impose no thread/goroutine-safety; all functions assume and expect they are being called from the same thread and thus share data that would cause race conditions if called from different threads/goroutines.
    • It's up to higher-level libraries to ensure thread-safe usage of these libraries.
  • normalgopher/gl and normalgopher/gl/fw do their best to mimic the standard go-gl/gl/go-gl/glfw interfaces, but some calls have been changed to mimic the WebGL version.
    • (Calls like GetInteger* replaced with GetParameter).
Shader Caveats

If you want to ignore the following caveats, you can prefix VertexShaderHeader() and FragmentShaderHeader() from the normalgopher/gl/help package to your shader source before shader compliation. If you choose to do this, make sure your shader source does not include the #version directive.

Otherwise, you'll need to keep the following in mind:

  • Shaders should be declare their version as: #version 300 es
  • Fragment shaders need to declare this near the top (but after the #version directive):
#ifdef GL_ES
   precision highp float;
#endif

Building/Running on Web

Since this project aims to provide a single library to build both desktop and web applications, choosing the build target is as simple as employing the GOOS and GOARCH.

Building for Web

Running the following will produce a main.wasm file that in conjuction with a wasm_exec.js file (found here) will allow your projects to run in the browser (with a bit of html).

GOOS=js GOARCH=wasm go build . -o main.wasm

Note: you can name your .wasm file something other than main.wasm.

Necessary HTML

Following is a minimal HTML file that will, in conjuction with main.wasm (your project) and wasm_exec.js, will execute your project.

<!DOCTYPE html>

<head>
   <meta charset="utf-8" />
   <script src="wasm_exec.js"></script>
   <script>
      const go = new Go();
      WebAssembly.instantiateStreaming(fetch("main.wasm"), go.importObject).then((result) => {
         go.run(result.instance);
      });
   </script>
</head>

<body style="border: none; margin: 0;">
   <canvas id="glfw"></canvas>
</body>

</html>
Three Important Things
  1. Your files (main.wasm and wasm_exec.js) need to be provided via a webserver; otherwise the annoynance that is CORS will refuse to load your files.
  2. If you chose to name your wasm something other than main.wasm, you'll need to update the WebAssembly.instantiateStreaming call to reference your specific filename.
  3. Where ever the HTML canvas is, it must have an id of glfw; otherwise, this library won't know what to hook into.
