glut

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 having trouble with resizing a GLUT window. I want to print a rectangle but when i use the resize function i cant seem to draw and shape in the window. I have the following code and i want to change with width of the square when i resize the window but if the height is resized i dont want the height of it to change. #include <GLUT/glut.h> #include <stdio.h> #include <stdlib.h> /* globals */ GLsizei wh = 500, ww = 500; /* initial window size */ GLfloat size = 3.0; /* half side length of square */ void myinit(void) { glClearColor(0.0,0.0,1.0,1.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(

I want to combine OpenGL with glut to Qt. I'm using Windows. My version of Qt is 4.7.4, 32 bit. I followed the tutorial: http://www.youtube.com/watch?v=1nzHSkY4K18 I also checked some other questions of people but they didn't gave me an answer. The part before including glut works fine. But when I try to include glut it doesn't work. The errors are: undefined reference to glutInit_ATEXIT_HACK and more undefined references to glutfunctions. I copied the glut-libraries and headers to the appropriate folders in the MinGW folder. But I wasn't sure if this was the right folder. MinGW: Copy glut.h

I am using a timer function to animate, but I am having issues when I place it in the Renderer class. void Renderer::animate(int value) { glutTimerFunc(TIMERMSECS, animate, 0); } Error: \renderer.cpp(242) : error C3867: 'Renderer::animate': function call missing argument list; use '&Renderer::animate' to create a pointer to member The issue is that Renderer::animate is a class member function and so has a hidden this parameter. glutTimerFunc doesn't know what value of this to pass, so if you somehow tried to sneak past the compiler with a nasty cast, it would crash at runtime. The solution is

I have code from the OpenGLBook (openglbook.com) which compiles, but does not load. I have absolutely no idea why it's not loading. The code is as follows: main.cpp #include "main.h" /// Methods /// ----------------------------- int main(int argc, char* argv[]) { Initialize(argc, argv); glutMainLoop(); exit(EXIT_SUCCESS); } main.h #ifndef main_h #define main_h #include <cstdlib> #include <cstdio> #include <cstring> #include <GL/glew.h> #include <GL/freeglut.h> #define WINDOW_TITLE_PREFIX "CHAPTER 1" void Initialize(int, char*[]); void InitWindow(int, char*[]); void ResizeFunction(int, int);

I've got a C / C++ (only main file is .cpp so I can use OpenGL) program, I use OpenGL (GLUT, GLUI) in it. It already displays something but I want it to move every x ms. I render some circles (known speed and coordinates) and I have already made the function that computes it's next position knowing the refresh rate. I've tried to put my display callback in a timer callback but the program just freezed. What can I do in order to run the display callback every x ms ? I've tried to put my display callback in a timer callback but the program just freezed. Make sure to re-arm the timer in your

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

I am beginner to GLUT in C++. I am using Dev C++ as my IDE. I have this simple triangle drawing code and it produces an error "redeclaration of C++ built-in type short ". But When I put #include<iostream.h> before #include<glut.h> , it compiles and runs. Can anyone explain the logic behind that? #include<glut.h> void renderScene(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glBegin(GL_TRIANGLES); glVertex3f(-0.5,-0.5,0.0); glVertex3f(0.5,0.0,0.0); glVertex3f(0.0,0.5,0.0); glEnd(); glutSwapBuffers(); } int main(int argc, char **argv) { // init GLUT and create Window glutInit(&argc

I am writing a simple glut Application, and my teacher wants me to create a top menu bar, as in any windows app(you know, file\edit etc, the ruler on the window's top). I looked in glut documentation and googled, all I can find is a popup menu that opens with mouse's right button - not what was defined. Dinesh Subedi GLUT library provide service like creating window, callback functions, timer, mouse event and key press. But you want to make window menu bar for which GLUT does not provide the built in function. GLUT is useful for game , simulation not for GUI. For that you have to use the GUI
