This example shows interaction with OpenGL library, to render classical 3D test model. Linux build requires apt-get install freeglut3-dev or similar, MacOS shall work as is.
To build use ../gradlew assemble.
To run use ../gradlew runReleaseExecutableOpengl or execute the program directly:
./build/bin/opengl/main/release/executable/opengl.kexe
It will render 3D model of teapot. Feel free to experiment with it, the whole power of OpenGL is at your hands.
