freeglut

I am working on a Mac, I've got FreeGlut compiled and installed, but I can't seem to get the OpenGL 3.2 context with it. However, I can get it without any problem while using GLFW. So in GLFW, this code works perfectly fine: glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 2); glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); glfwOpenWindow(500, 500, 8, 8, 8, 8, 24, 8, GLFW_WINDOW) But with FreeGlut, this code fails(on glutCreateWindow ): glutInitContextVersion (3, 2); glutInitContextProfile(GLUT_CORE_PROFILE); glutInitWindowSize

I get how glutdisplayfunc() makes the display loop and Iv read in some places that you should put the game mechanics in glutidle instead of the display; why can't you just put them in a while (gameisrunning) loop? In event-driven programming, like you have in interactive OpenGL applications, the main application loop generally does three things: check the current event queues, and process any events (e.g., mouse movement, key presses, etc.) that have occurred since the last check update the application state - things like player and object positions, game physics, etc. - in preparation of the

My university started teaching a course which includes OpenGL programming. They make us use FreeGLUT to create a window and a context for OpenGL, but I found an online course at lynda.com about OpenGL in which they use GLFW instead of FreeGLUT. So I want to know which one should I use and what are the differences between the two? FreeGLUT: Based on the GLUT API. GLUT has been around for about as long as OpenGL itself. Many tutorials and examples out there use GLUT. Takes care of implementing the event loop and works through callbacks (good for simple stuff, makes things like precisely timed

Ok so im setting up Visual studios C++ 10 on Windows 7 so i can run the sample progams from this book "OpenGL superbible 5th edition" but i'm having some MAJOR ISSUES, in getting GLTools and freeglut to wok: Here's how I set everything up so far......................... fist followed these steps i got online: first youl want to download glut or freeglut, then unzip it ofc. - I got this from the zip file at http://www.starstonesoftware.com/OpenGL/ In the freeglut folder there should be a folder called VisualStudio2008, go into this. There should be a VS project file called freeglut, run this

I'm trying to use stuff like glShaderSource in C++. Visual Studio says that functions like glCompileShader or glCreateProgram dont exist. I use FreeGLUT to include OpenGL. Does anybody have an idea how I can fix this? On windows, anything beyond GL1.1 must be loaded via the extension mechansim. The most convenient way to do so is by using a GL loader like glew . 来源： https://stackoverflow.com/questions/20722756/problems-with-shaders-in-opengl

I'm working on a project that utilizes freeglut and GLEW . In order to use the vertex and fragment shaders in my program, the minimum OpenGL version I need to use is 3.3 . I have checked the OpenGL version and GLSL version and this is the result: [cyclonite@localhost ~]$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel (R) HD Graphics 620 (Kaby Lake GT2) OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.3 OpenGL core profile shading language version string: 4.50 OpenGL core profile context flags: (none) OpenGL
