framebuffer_size_callback()

void framebuffer_size_callback	(	GLFWwindow *	window,
		int	width,
		int	height
	)

Callback to adjust the size of the viewport when the window is resized.

Parameters

window	The current window.
width	The new width.
height	The new height.

initialize_framebuffer()

unsigned int initialize_framebuffer	(	unsigned int *	framebuffer,
		unsigned int *	texture_color_buffer,
		unsigned int	texture_width,
		unsigned int	texture_height
	)

Initialize a framebuffer and the associated texture.

Parameters

framebuffer	The framebuffer ID to be initialized.
texture_color_buffer	The texture ID to be initialized.
texture_width	The width of the desired texture image.
texture_height	The height of the desired texture image.

Returns

0 on success, 1 on failure.

initialize_vertices()

unsigned int initialize_vertices

(

)

Initialize the vertex array.

This functions defines a simple rectangle containing the whole viewport.

Returns

The vertex array object ID.

initialize_window()

GLFWwindow* initialize_window	(	int	width,
		int	height
	)

Initialize GLFW and OpenGL, and create a window.

Parameters

width	The width of the window to create.
height	The height of the window to create.

Returns

A pointer to the newly created GLFW window, or NULL on error.
