glut

I'm on Linux Mint 13 XFCE. My problem is that when I run in terminal the command: glxinfo | grep "OpenGL version" I get the following output: OpenGL version string: 3.3.0 NVIDIA 295.40 But when I run the glGetString(GL_VERSION) in my application then the result is null. Why doesn't this code get the gl_version ? #include <stdio.h> #include <GL/glew.h> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> #include <GL/glext.h> int main(int argc, char **argv) { glutInit(&argc, argv); glewInit(); printf("OpenGL version supported by this platform (%s): \n", glGetString(GL_VERSION)); }

In my simple OpenGL program I get the following error about exit redefinition: 1>c:\program files\microsoft visual studio 8\vc\include\stdlib.h(406) : error C2381: 'exit' : redefinition; __declspec(noreturn) differs 1> c:\program files\microsoft visual studio 8\vc\platformsdk\include\gl\glut.h(146) : see declaration of 'exit' I'm using Nate Robins' GLUT for Win32 and get this error with Visual Studio 2005 or Visual C++ 2005 (Express Edition). What is the cause of this error and how do I fix it? Cause: The stdlib.h which ships with the recent versions of Visual Studio has a different (and

How do I draw a text string onto the screen using GLUT / OpenGL drawing functions? epatel There are two ways to draw strings with GLUT glutStrokeString will draw text in 3D (source: uwa.edu.au ) and glutBitmapString will draw text facing the user (source: sourceforge.net ) Adam Rosenfield If you don't like the built-in stroke font or bitmap font that comes with GLUT as per epatel's answer , you'll have to roll your own solution. NeHe has some good tutorials (along with fully-working sample code) on this: Lesson 13 - Bitmap Fonts Lesson 14 - Outline Fonts Lesson 15 - Texture-Mapped Outline

every introduction and sample that I can find seems to use GLUT or some other framework to "initialize" OpenGL. Is there a way of initializing OpenGL with just what is available in GL and GLU? If not, then what is GLUT doing that is not possible without it? As luke noted, the code to create and bind the context is specific to each windowing platform. Here are some functions to get you started in terms of initializing OpenGL on specific platforms: Windows (a tutorial is here ) wglCreateContext(hDC) Mac OS X -- OS X has essentially three options: Carbon, Cocoa, and the underlying Core Graphics

I was trying to build an opengl program on qt creator, installed on my mac, with osx 10.9. I got several warnings on glut functions about its deprecation in osx10.9, a sample error message is like: 'glutInit' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] glutInit(&argc, &argv); ^ I wonder if GLUT.h is not usable anymore in osx10.9? According to some other posts, it is said that as long as we change "OS X Deployment Target" back to OSX10.8, then it works. How to do so in qtcreator? Thank you! You can still use it in 10.9. They're sending you a pretty strong signal

Is it possible to use GLUT on OS X Lion or OS X Mountain Lion using core profile (so I can use GLSL 1.50)? Can I use the built in GLUT or do I need to use a third-part library such as FreeGLUT? And is there any simple 'Hello world' applications available for OS X with either an XCode project or a make-file? You need at least Mac OS X Lion (OS X 10.7 or higher) for the basic support of OpenGL 3.2. To use the OpenGL 3.2 Core Profile, just add glutInitDisplayMode(GLUT_3_2_CORE_PROFILE | ... | ...); in your main -function. You can check it by std::printf("%s\n%s\n", glGetString(GL_RENDERER), // e

I want to use the mouse scrollwheel in my OpenGL GLUT program to zoom in and out of a scene? How do I do that? BentFX Freeglut's glutMouseWheelFunc callback is version dependant and not reliable in X. Use standard mouse function and test for buttons 3 and 4. The OpenGlut notes on glutMouseWheelFunc state: Due to lack of information about the mouse, it is impossible to implement this correctly on X at this time. Use of this function limits the portability of your application. (This feature does work on X, just not reliably.) You are encouraged to use the standard, reliable mouse-button
