I think my problem is similar to this post, which was never solved:
I tried to follow this snack that I found, but it has the same issue (I exported to XDE as the snack itself reports “No experience found”)
My code is like the following:
<Expo.GLView
ref={(ref) => this._glView = ref}
style={{ flex: 1 }}
onContextCreate={this._onGLContextCreate}
/>
_onGLContextCreate = async (gl) => {
// Some code to create AR scene, not shown here
let animate = () => {
requestAnimationFrame(animate);
renderer.render(scene, camera);
gl.endFrameEXP();
//Finger detection, run every 10 drawing cycles
if(cycle_idx === 0){
let pixels = new Uint8Array(width * height * 4);
console.debug(pixels[4] + " " + pixels[5] + " " + pixels[6] + " " + pixels[7]);
console.debug(width + " " + height);
gl.readPixels(0, 0, width, height, gl.RGBA_INTEGER, gl.UNSIGNED_BYTE, pixels);
//contrusct an ImageData object from pixels and analyze
//TODO: somehow the readPixels return all 0 values, interesting
console.debug(pixels[240] + " " + pixels[241] + " " + pixels[242] + " " + pixels[7]);
HGD.frameAnalyzer(width, height, pixels);
}
}
animate();
}
}
Additionally, this was part of a project that is using the Expo ARkit.
I would really appreciate any help, thank you in advance.
