Telling GLFW we want to use the core-profile means we'll get access to a smaller subset of OpenGL features without backwards-compatible features we no longer need. We also tell GLFW we want to explicitly use the core-profile. We set the major and minor version both to 3. This ensures that when a user does not have the proper OpenGL version GLFW fails to run. This way GLFW can make the proper arrangements when creating the OpenGL context. Since the focus of this book is on OpenGL version 3.3 we'd like to tell GLFW that 3.3 is the OpenGL version we want to use. If you try to run the application now and it gives a lot of undefined reference errors it means you didn't successfully link the GLFW library. A list of all the possible options and its corresponding values can be found at GLFW's window handling documentation. The second argument is an integer that sets the value of our option. The first argument of glfwWindowHint tells us what option we want to configure, where we can select the option from a large enum of possible options prefixed with GLFW_.
In the main function we first initialize GLFW with glfwInit, after which we can configure GLFW using glfwWindowHint. glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE) GlfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE) GlfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3) GlfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3) Next, we create the main function where we will instantiate the GLFW window: The include file for GLAD includes the required OpenGL headers behind the scenes (like GL/gl.h) so be sure to include GLAD before other header files that require OpenGL (like GLFW). cpp file and add the following includes to the top of your newly created file.īe sure to include GLAD before GLFW. Let's see if we can get GLFW up and running.

OPENGL EXTENSIONS VIEWER CRASHES TRIAL
Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited. In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces. In some cases, ads may be show to the users. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes.
