Detailed Description

A generic base class for GLFW-applications.

This abstract class creates a window when created and provides hooks for initializing, updating, rendering and resizeing. There are also extra hooks for a GUI. It will also provide information about the mouse-position.

Constructor & Destructor Documentation

GLFWApplication::GLFWApplication ( int  width,
int  height,
int  ctx_major,
int  ctx_minor 
)

Creates a new instance with the given parameters.

Parameters
widththe initial width of the window
heightthe initial height of the window
ctx_majorthe requested major version of OpenGL
ctx_minorthe requested minor version of OpenGL

Member Function Documentation

virtual void GLFWApplication::resize ( int  width,
int  height 
)
pure virtual

This method will be called if the size of the window changes.

Parameters
widththe new width of the window
heightthe new height of the window

Implemented in Vis2Application.

void GLFWApplication::run ( )

This method starts the update-render-loop and returns if the window has been closed.

First the initializers init() and initUI() will be called.

In the main-loop the color and depth buffer will be cleared first, then the time of the last frame will be calculated.

Also the mousepositions receive an update and the hooks update(), render() and renderUI() will be called in that order.
