glut

问题 I am using #include <gl/freeglut.h> but getting " fatal error: GLUT/freeglut.h file not found " ** I tried reinstall "brew install glew freeglut" and also " #ifdef __APPLE__ #include <OpenGL/gl.h> #include <GLUT/glut.h> #else #include <GL/gl.h> #include <GL/glut.h> #endif" I also tried: #include <GL/freeglut.h> but none of them worked... 来源： https://stackoverflow.com/questions/65655868/fatal-error-glut-freeglut-h-file-not-found-catalina

问题 Recently I had this issue. Now that I've fixed that with given solution, I ran into some other issues. Here is a gif of the animation I have to achieve. Issues I have now are: the ball in my animation doesn't look like it's moving forwards and backwards like it is at the beginning of the .gif. I do believe this has something to do with Ortho but I don't know how to fix this. Also, at some point, when it's moving completely to the right, the moving ball and torus just get "swallowed", it's

问题 Simply, I am just trying to show a 3d point but nothing show on! How to show it? what is wrong in the code below, anybody can help? init: void init(void) { glClearColor(0.0, 0.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glOrtho(-200, 0.0, -50, 100, 70, 300); } display: void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glColor3f(1.0, 1.0, 1.0); glPointSize(2); glBegin(GL_POINTS); glVertex3f(-120.0, 25.0, 0.0)

问题 I installed the OpenGL in Linux server (Ubuntu16.04) without a graphical interface, install command below: apt-get install build-essential libgl1-mesa-dev libglu1-mesa-dev apt-get install freeglut3-dev libglew1.10 libglew-dev libgl1-mesa-glx libxmu-dev apt-get install libglew-dev libsdl2-dev libsdl2-image-dev libglm-dev libfreetype6-dev apt-get install mesa-utils now, I compile light.c by gcc light.c -o light -lGL -lglut . I want to display it in my Windows mechine by XMing server. code:

问题 I draw patterns which have detailed pixels and they often face with Moire effect. I am not good at shading and I am not sure if this problem will be solved by shaders. I have not found any basic, understandable and complete example of shaders. Most of the tutorial websites start a program from the middle omitting the header file includes! This is a MWE of my code. Is it possible to mitigate or remove the Moire effect from it? #include <cmath> #include <vector> #ifdef __APPLE__ #include <GLUT

问题 I have made a bit of a change to my code in the last couple of hours as everything was messy with my grid so I made it into a void and I made sure I got the boundary that I was drawn out first as it is now placed where I want it to be, however my grid is now in the wrong place shown in the image below I think it is a glortho issue but I don't know what code to put in which will change where I want my drawings to be placed. #include "include\freeglut.h" // OpenGL toolkit - in the local shared
