This example initializes the display in glfmMain() and draws a triangle in onDraw(). NDEBUG is automatically defined for release builds in Android Studio, but not in Xcode. Include a void glfmMain(GLFMDisplay *display) function in a C/C++ file.įor release builds, define NDEBUG to remove superfluous logging statements.Add the GLFM source files (in include and src) to your project.Use GLFMĪ CMakeLists.txt file is provided for convenience, although CMake is not required. Instead, GLFM can be used with other cross-platform libraries that provide what an app needs. No integration with other mobile features like web views, maps, or game scores.For example, GLFM doesn't provide (and will never provide) the following:

GLFM is limited in scope, and isn't designed to provide everything needed for an app. There is no function to set the window size, for example. The macOS version is useful for development purposes, but is not release quality. OpenGL context loss events (surface destroyed)Īdditionally, there is prelimnary support for macOS with OpenGL 3.2.

Events for application state and context loss.Īccelerometer, magnetometer, gyroscope, device rotation.

Accelerometer, magnetometer, gyroscope, and device rotation (iOS/Android only).

OpenGL ES 2, OpenGL ES 3, and Metal display setup.

GLFM runs on iOS 9, tvOS 9, Android 4.1 (API 16), and WebGL 1.0 (via Emscripten).Īdditionally, GLFM provides Metal support on iOS and tvOS. GLFM is a C API for mobile app development with OpenGL ES.
