What does major and minor mean in OpenGL with GLFW?

由 为君一笑 提交于 2021-02-19 06:05:26
问题 I was creating an OpenGL window with GLFW on some Dell PC that used integrated graphics. I thought that major means maximum and minor means minimum. However having a restricted version range of (3,3) works but a range that contains it such as (4,2) fails. Example: //fails glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); //fails glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); //success glfwWindowHint

glGenFramebuffers() access violation when using GLFW + GLEW

问题 I am getting this error: "Access violation executing location 0x00000000." when I use GLFW + GLEW on Windows. I am using Windows 7. I also have my own implementation (from scratch) that that creates a window, initializes OpenGL context, initializes GLEW, etc... and everything works fine. So of course my video card has the Frame Buffer capability and everything is pretty fine with the drivers... the problem only happens when I try to use GLFW. Any suggestion? The code: void start() { if(

Linking GLEW and others, _glViewport is the only unresolved

问题 I'm using G++ to link my project to glew32, glfw, opengl32, glu32, etc, everything compiles fine - however at the link stage everything but glViewport links and I get this error: undefined reference to '_glViewport'. I find this... odd since everything else was fine and I'm kinda at a loss for what to do. I look forward to any advice on what to try and or do. 回答1: As per my comment, you need to link with the OpenGL libraries, when you compile do (Linux/cygwin) g++ -o target source.c -lGL To

Texturing a cube with different images using OpenGL

问题 I have a project from school I'm currently working on and I need to texture a non-rotating cube showing just 3 faces. I've tried doing it on my own but I only get one image on all the 3 faces. I don't know if it's my method that's wrong or the way I'm loading the remaining two images. I would really appreciate help from anyone. This is how I load my textures GLuint VAO, VBO; glGenVertexArrays(1, &VAO); glGenBuffers(1, &VBO); glBindVertexArray(VAO); glBindBuffer(GL_ARRAY_BUFFER, VBO);

How to link to native libraries in a Visual Studio Code project?

由 独自空忆成欢 提交于 2021-01-05 07:24:05
问题 I am learning OpenGl and I am new to ms Visual Studio Code. I want to add GLEW and GLFW to visual studio code. I have been only able to add header files and it's been 2 weeks from then and I still haven't been able to figure out how to add libraries of GLEW and GLFW to vscode. All the tutorials on the Internet are made for past versions of the visual studio by creating an empty project. But this empty project option is not available in Visual Studio Code. So, please help me to figure this out

CMake can't find GLEW

问题 I've read this [1], but in my case CMake says it can't find glew. I'm on Windows and there is a FindGLEW.cmake file in my CMake modules folder, presumably put there when I installed CMake-3.6. I found GLEW on sourceforge and downloaded the zip file for Windows. I unzipped and installed in C:\Program Files\glew. When I've created my own libraries and used CMake to build and install them, this is the default location they are installed to so I am pretty confident I'm OK here. The snippet from

【游戏开发】基于VS2017的OpenGL开发环境搭建

由 ∥☆過路亽．° 提交于 2020-08-20 09:35:29
一、简介 　　最近，马三买了两本有关于“计算机图形学”的书籍，准备在工作之余鼓捣鼓捣图形学和OpenGL编程，提升自己的价值（奔着学完能涨一波工资去的）。俗话说得好，“工欲善其事,必先利其器”。想学习图形学和OpenGL编程必须先把开发环境搭建好，而马三只是在上学的时候稍稍做了一些基于Android平台的OpenGL开发学习，并没有搭建过OpenGL开发环境。因此在搭建过程中颇废了一番周折，也查阅了不少资料才算搭建成功，特此记录一下搭建过程，以备不时之需。 二、搭建环境 1.VS2017 　　这个不必多说了，基本做过开发的都会安装这个“宇宙最强IDE”了。直接去官网下载安装助手，然后安装即可。 2.GLFW库 　　正常来说开发进行OpenGL开发的话，glut库是必不可少的，但是马三在网上一搜啊，发现glut这个库过时了，现在比较新版的GLFW完全可以替代它。关于这些名词相关的具体介绍，我们会在稍后仔细介绍一下，我们还是先去 GLFW官网 把库下载下来。 　　 图1：GLFW官网下载示意图 3.GLEW库 　　接着我们还需要下载GLEW库，众所周知，OpenGL只是一个标准，不同的显卡公司在不同的平台下对其有不同的实现，同时也是发布一些只支持自家显卡的拓展函数。通过引入glew库，我们完全可以不用理睬这些细节，安心写代码就好了。 　　同样还是去 GLEW的官网 下载我们所需要的内容
