ComposeGL

This library adds a GLCanvas composable which allows high-performance 2D and 3D rendering within any
Compose Multiplatform application.
It also provides a lightweight abstraction to access GLES and Desktop GL using a common API up to GLES 3.0.

Platform support

	Android	iOS	macOS	Windows	Linux	Web
API Level	GLES 3.2	GLES 3.0	GL 4.1/GLES 2.0	GL 4.6/GLES 2.0	GL 4.6/GLES 2.0	GLES 3.0
Backend	GLES	ANGLE	Desktop GL	Desktop GL	Desktop GL	ANGLE
*Skiko Backend	GLES	Metal	Desktop GL	Desktop GL	Desktop GL	GLES

*In order to guarantee proper interoperability, ComposeGL forces Compose to use
the specified Skiko backend on the respective platforms.

The common API level as of the last time updating this table is GLES 2.0,
which is available on all listed platforms without exceptions.

GLES 3.X support is planned once ANGLE finishes their implementation, which
allows using GLES 3.2 on iOS and Web.

How to use it

// Make sure to call ComposeGL.setup() before
// initializing the main view of your App.

@Composable
fun MyApp() {
    GLCanvas(
        onDispose = { /* Callback when canvas is disposed */ },
        fallbackContent = { Text("ComposeGL is not supported") }
    ) {
        val shader = memoize { GLShader(...) }
        glClearColor(0F, 0F, 0F, 1F)
        glClear(GL_COLOR_BUFFER_BIT)
        shader.use {
            // Your rendering code here
        }
    }
}
