Make My Own Screensaver


git clone https://github.com/rougier/freetype-gl
cd freetype-gl
mkdir build
cd build
cmake ..

But first, I had to install:

cmake
doxygen
glfw-x11 (version 3.something)

The demos in build/demos work now, and I started hacking on them.

Ripped out the screenshot bits.

To make them fullscreen:

GLFWmonitor* monitor = glfwGetPrimaryMonitor();
const GLFWvidmode* mode = glfwGetVideoMode(monitor);

window = glfwCreateWindow( mode->width, mode->height, argv[0], monitor, NULL );

Replaces a single line like this:

window = glfwCreateWindow( 850, 200, argv[0], NULL, NULL );

Several absolute pixel dimensions as in the example above also need to be replaced by

mode->width, mode->height

Remove:

glfwPollEvents( );

Now the window won't react to the Escape key anymore and needs to be killed. Until I find a way in C to exit upon any sort of keyboard or mouse event, this will be part of a shell wrapper script.
