Question 1

How do I set up GLFM in Android Studio?

Accepted Answer

Follow the README steps: create a new project with no activity, modify AndroidManifest.xml to include a NativeActivity, and add externalNativeBuild in build.gradle with the GLFM CMakeLists.txt path. Ensure assets are linked from the examples folder.

Question 2

GLFM vs GLFW: which should I use for mobile development?

Accepted Answer

Use GLFM for cross-platform mobile and web apps with OpenGL ES or Metal, as it's tailored for iOS, Android, and WebGL. GLFW is better for desktop-focused projects, though GLFM's design makes porting from GLFW straightforward.

Question 3

Does GLFM support the Vulkan graphics API?

Accepted Answer

No, GLFM only supports OpenGL ES and Metal, as stated in the features. For Vulkan, you'd need to use other libraries or platform-specific APIs, as GLFM focuses on its stated goals.

Question 4

Can I use GLFM to build desktop applications?

Accepted Answer

Only for development purposes; the macOS version is preliminary and lacks features like window size control. For production desktop apps, GLFW is recommended, and the README suggests using it for desktop and porting to GLFM later.

Question 5

How do I handle touch input events in GLFM?

Accepted Answer

Set callback functions using glfmSetTouchFunc() to receive touch events, with details in glfm.h. The examples, like touch.c, demonstrate processing touch coordinates and gestures across platforms.

Question 6

Is GLFM suitable for developing 3D mobile games?

Accepted Answer

Yes, for low-level 3D rendering with OpenGL ES or Metal, but you'll need to handle assets, audio, and UI separately. It's ideal for custom engines but not for teams wanting an all-in-one solution like Unity.
