freeglut

问题 I just started trying to folow simple "draw cube" openGl tutorial. After final victory over getting OpenGL to work, I still have very veird results. My problem is that the objects tend to resize themselves to match the window size. Instead, I'd like the window size determine the rendering area - the larger the window is, the more you may see. Here are some screenshots of the resizing : Normal size Resized Images kept as links intentionally! This auto-resizing behavior brings a question what

问题 I recently tried to figure out how to use freeglut with NetBeans 7. I Google'd a lot and I didn't find a suitable tutorial on how to bind the stuff I need into it. Currently I have more problem then this: First one is: - freeglut 2.8 => in order to compile it I need MinGW and msys. I have both installed but I can't "configure" or "make all" and "make install" freeglut. I didn't find an easy-to-read how-to for that task. Next one: - once built, where to put what files into a specific folder?

问题 I am trying to install freeglut on my computer running Linux Mint. I follow the steps on this website: http://freeglut.sourceforge.net/docs/install.php. When I do make all in the src directory, it gives the following error: fatal error: GL/gl.h This error was given by ../include/GL/freeglut_std.h. Upon inspection, the include/GL directory is indeed devoid of any gl.h file. It is also missing glu.h, which freeglut_std.h also tries to #include . What should I do about this? Why are gl.h and glu

问题 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

问题 I have a code to find the cell mouse clicked in chess board then a 2D Triangle shape go to the cell position, Now I want to change 2D Triangle to 3D cube but I don't know how to do that. This my code #include <string> #include <stdlib.h> #ifdef __APPLE__ #include <OpenGL/OpenGL.h> #include <GLUT/glut.h> #else #include <GL/glut.h> #endif #include <iostream> using namespace std; void init() { glClearColor (1.0, 0.0, 1.0, 0.0); glShadeModel (GL_FLAT); } const int scl = 80 ; const int STEP_SIZE =

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I'm trying to get FreeGLUT working. For a reason I don't get, no binaries are distributed. Where can I download the .lib and the .dll files? 回答1: You can download them at FreeGLut download page, in section Prepackaged Releases Direct Link Please note it's community-maintained. Library authors only do provide

问题 When I rotate my fps camera using mouse the animation is not smooth. When I use a keyboard everything works nice. For keyboard I use an array of type bool to buffer keys. What Can I do to make the animation smooth when using mouse ? void MousePassiveMotion(int x, int y) { int centerX = glutGet(GLUT_WINDOW_WIDTH) / 2; int centerY = glutGet(GLUT_WINDOW_HEIGHT) / 2; int deltaX = x - centerX; int deltaY = y - centerY; if(deltaX != 0 || deltaY != 0) { heading = deltaX * 0.2f; pitch = deltaY * 0.2f

问题 I'm using MSVC++ and freeglut in order to use openGL. Now, I have a class called Camera , which is pretty simple, but it also holds the function for the reshaping of my window. My question is: how can I set glutReshapeFunc(void (*callback)(int,int)) to my function in my camera? I have the following code, which won't work, because of a compiler error: int main(int argc, char **argv) { Camera *camera = new Camera(); glutReshapeFunc(camera->ReshapeCamera); } and my Camera class looks like this

问题 I'm trying to compile an OpenGL program using Visual Studio 2013, but I get the following error: Error 1 error LNK1104: cannot open file 'freeglutd.lib' ... For reference, I have FreeGLUT installed and have configured VS to search the correct directories for the include files and library files. Indeed, VS recognises the GLUT include files just fine. I've also added opengl32.lib and freeglut.lib to the Additional Dependencies . Why is VS looking for 'freeglutd.lib'? It's definitely not listed

问题 I'm going to show FPS on the screen with the freeglut function glutBitmapString,but it shows nothing. Here is my code. Is there anyone can figure where the problem is? void PrintFPS() { frame++; time=glutGet(GLUT_ELAPSED_TIME); if (time - timebase > 100) { cout << "FPS:\t"<<frame*1000.0/(time-timebase)<<endl; char* out = new char[30]; sprintf(out,"FPS:%4.2f",frame*1000.0f/(time-timebase)); glColor3f(1.0f,1.0f,1.0f); glRasterPos2f(20,20); glutBitmapString(GLUT_BITMAP_TIMES_ROMAN_24,(unsigned
