freeglut

Here is my source code I'm trying to get to work: In Main.hs: import Graphics.Rendering.OpenGL import Graphics.UI.GLUT import Bindings import Data.IORef main = do (progname,_) <- getArgsAndInitialize createWindow "Hello World" reshapeCallback $= Just reshape keyboardMouseCallback $= Just keyboardMouse angle <- newIORef 0.0 displayCallback $= display idleCallback $= Just idle mouseWheelCallback $= Just mouseWheel mainLoop In Bindings.hs: module Bindings where import Graphics.Rendering.OpenGL import Graphics.UI.GLUT display :: IO () display = return () overlayDisplay :: IO () overlayDisplay =

I am running Linux Mint 14.1 64-bit I have installed the following libs: mesa-common-dev, freeglut3-dev, libglew-dev through the apt-get tool. Here are my includes, located in my Main.h file: #include <cmath> #include <cstdlib> #include <iostream> #include <stdio.h> #include <GL/glew.h> #include <GL/glut.h> #include <time.h> I checked that the libs installed correctly, they seem to be located in /usr/lib/x86_64-linux-gnu and the headers in /usr/include/GL I proceed to compile my Main.C file with the following flags: g++ -Wall -Wextra -Weffc++ -Winit-self -Wmissing-include-dirs -Wswitch-default

I'm really having trouble closing my console application with FreeGLUT. I would like to know what the best way is to take every possible closing, because I don't want any memory leaks (I'm pretty afraid of those). So I already tried the following, which is giving me an exception like this: First-chance exception at 0x754e6a6f in myProject.exe: 0x40010005: Control-C. int main(int argc, char **argv) { if( SetConsoleCtrlHandler( (PHANDLER_ROUTINE) CtrlHandler, true) ) { // more code here as well .... glutCloseFunc(close); // set the window closing function of opengl glutMainLoop(); close(); //

I'm trying to read some OpenGL tutorials on the net. the problem is that I found some old ones that use gluPerspective() . gluPerspective was deprecated in OpenGL 3.0 and removed in 3.1. What function can I use instead? I'm using C++ with latest FreeGlut installed. Dan You have to compute the matrix manually and then pass it to OpenGL. Computing the matrix This snippet of code is based on the gluPerspective documentation . void BuildPerspProjMat(float *m, float fov, float aspect, float znear, float zfar) { float f = 1/tan(fov * PI_OVER_360); m[0] = f/aspect; m[1] = 0; m[2] = 0; m[3] = 0; m[4]

Good evening, Right now I'm trying to run the following code using Xcode, but it has been impossible so far. The code is a from a simple tutorial I found online, and the code is supposed to simply draw a triangle using OpenGL and VBOs. If I try the code using Visual Studio, I actually get the expected result with no problems at all. However, when I try to run the code using Xcode, I only get a black screen. To setup the project in Xcode, I installed GLEW and FreeGlut using MacPorts and then I installed XQuartz 2.7.5. Then I created a new project in xcode as a command line tool, and in the

I'm trying to draw a rainbow-coloured plot legend in openGL. Here is what I've got so far: glBegin(GL_QUADS); for (int i = 0; i != legendElements; ++i) { GLfloat const cellColorIntensity = (GLfloat) i / (GLfloat) legendElements; OpenGL::pSetHSV(cellColorIntensity*360.0f, 1.0f, 1.0f); // draw the ith legend element GLdouble const xLeft = xBeginRight - legendWidth; GLdouble const xRight = xBeginRight; GLdouble const yBottom = (GLdouble)i * legendHeight / (GLdouble)legendElements + legendHeight; GLdouble const yTop = yBottom + legendHeight; glVertex2d(xLeft, yTop); // top-left glVertex2d(xRight,
