OpenGL 开发环境配置(Windows) - Visual Studio 2017 + GLFW + GLAD 详细教程

OpenGL环境配置一般选择Win32,因此本教程将搭载Win32平台的开发环境。 OpenGL开发环境配置 目录 搭建环境 配置步骤 Step1. 下载编译好的GLFW库 Step2. 下载GLAD库 Step3. 配置Visual Studio工程 其他问题 目录 搭建环境 操作系统:Windows 10 编译器:Visual Studio 2017 GLAD库 GLFW库 配置步骤 Step1. 下载编译好的GLFW库 下载链接: https://www.glfw.org/download.html . 下载选择的版本 Step2. 下载GLAD库 GLAD是一个开源的库,它能解决我们上面提到的那个繁琐的问题。GLAD的配置与大多数的开源库有些许的不同,GLAD使用了一个在线服务。在这里我们能够告诉GLAD需要定义的OpenGL版本,并且根据这个版本加载所有相关的OpenGL函数。 打开GLAD的 在线服务 .,将语言(Language)设置为C/C++,在API选项中,选择3.3以上的OpenGL(gl)版本(我们的教程中将使用3.3版本,但更新的版本也能正常工作)。之后将模式(Profile)设置为Core,并且保证生成加载器(Generate a loader)的选项是选中的。现在可以先(暂时)忽略拓展(Extensions)中的内容。都选择完之后,点击生成

LearnOpenGL-第一课:创建窗口

巧了我就是萌 提交于 2020-01-30 07:14:49
创建窗口 在我们画出出色的效果之前,首先要做的就是创建一个OpenGL上下文(Context)和一个用于显示的窗口。然而,这些操作在每个系统上都是不一样的,OpenGL有目的地从这些操作抽象(Abstract)出去。这意味着我们不得不自己处理创建窗口,定义OpenGL上下文以及处理用户输入。 幸运的是,有一些库已经提供了我们所需的功能,其中一部分是特别针对OpenGL的。这些库节省了我们书写操作系统相关代码的时间,提供给我们一个窗口和上下文用来渲染。最流行的几个库有GLUT,SDL,SFML和GLFW。在教程里我们将使用GLFW。 GLFW是一个专门针对OpenGL的C语言库,它提供了一些渲染物体所需的最低限度的接口。它允许用户创建OpenGL上下文,定义窗口参数以及处理用户输入,这正是我们需要的。本节和下一节的目标是建立GLFW环境,并保证它恰当地创建OpenGL上下文并显示窗口。这篇教程会一步步从获取、编译、链接GLFW库讲起。我们使用的是Microsoft Visual Studio 2015 IDE(操作过程在新版的Visual Studio都是相同的)。如果你用的不是Visual Studio(或者用的是它的旧版本)请不要担心,大多数IDE上的操作都是类似的。 构建GLFW GLFW可以从它官方网站的 下载页 上获取。GLFW已经有针对Visual Studio 2013

Using mingw32 glfw3 and glew32s binaries in cygwin32 without mixing cygwin X11 GLX with WGL

ⅰ亾dé卋堺 提交于 2020-01-24 15:40:32
问题 I want to use the cygwin32 compiler instead of mingw32. According to http://web.eecs.umich.edu/~sugih/courses/eecs487/glut-howto/glfw/ , the GLX programs of gl on cygwin don't work with glfw. So I tried to use mingw32 binaries of glfw3 in cygwin32, which gave errors like 'GL_ARRAY_BUFFER' was not declared in this scope. I solved that by linking with mingw32 binaries of glew32, which gave /usr/include/w32api/GL/glu.h:68:79: error: expected ')' before '*' token which I solved two different ways

OpenGL Rendering Constricted to bottom left quarter of the screen

旧时模样 提交于 2020-01-24 06:28:09
问题 So I'm working on an OpenGL project in C++ and I'm running into a weird issue where after creating the GLFWwindow and drawing to it, the area that I'm drawing in only encompasses the bottom left quarter of the screen. For example if the screen dimensions are 640x480, and I drew a 40x40 square at (600, 440) it shows up here, instead of in the top right corner like I would expect: If I move the square into an area that's not within the 640x480 parameter it gets cut off, like below: I'll post my

Once in a while (mainly after editing a file), I get following error while compiling: ----- SRC ----- (150 B) #version 330 core uniform mat4 mvpMatrix; in vec4 vertexPosition_modelspace; void main() { gl_Position = mvpMatrix * vertexPosition_modelspace; } gp! ----- END ----- SimpleTransform.vertexshader:Vertex shader failed to compile with the following errors: ERROR: 0:10: error(#132) Syntax error: 'gp' parse error ERROR: error(#273) 1

Thread Setup for GLFW

心已入冬 提交于 2020-01-23 09:04:04
问题 I started working with the new Lwjgl 3 which uses GLFW for its Display/mouse/keyboard handling and I'm really liking it! However today i hit a brick. I had a simple rendering animation going but when I dragged the screen it stopped rendering until i let go again. According to: http://www.glfw.org/faq.html The problem arises due to windows. 3.5 - Why does my application freeze when I move or resize the window? The Windows event loop is blocked by certain actions like dragging or resizing a

本教程严格按照 https://learnopengl-cn.github.io/ 教程来学习与总结以及问题,本教程只会说明博主本人遇到的问题与解决方案。 在开始编程前,你需要配置环境。 一、环境 window10 (1903) 16G CPU:I5-6600K IDE:VS2019 OpenGL:3.3 二、配置环境 cmake:vs是自带cmake的,但是怎么尝试都不行,没有生成 glfw3.lib 按照教程走,没有遇到问题 把各种头文件新建文件夹中,并在IDE中设置好“包含目录”和“库目录”路径。 可能会遇到找不到头文件的情况:比如 #include <glad/glad.h> #include <GLFW/glfw3.h> 这是因为“/”是指文件夹中的意思,也就是不能仅仅把文件复制到自建的文件夹中,要把本身的文件夹复制进来,可以说是习惯问题,但是大家都这么写,为了头文件的一致性,所以还是这样来比较好。 配置完成后,新建cpp,能运行不报错就算配置完成了,如果你是macos,需要注释掉的代码,但我记得xcode貌似很方便。 #include <glad/glad.h> #include <GLFW/glfw3.h> #include <iostream> int main() { glfwInit(); glfwWindowHint(GLFW_CONTEXT_VERSION

问题 Ubuntu 14.04 , GLFW 3.2.1 , OpenGL 4.5.0 NVIDIA 367.57 I am trying to build the "Hello Triangle" OpenGL Example found at http://antongerdelan.net/opengl/hellotriangle.html but I am running into trouble. I downloaded the GLFW source and built out-of-source and installed with no extra flags or options. Below is the src/CMakeLists.txt file for Hello Triangle that is assembled from both the GLFW and from SO answers. After wrestling with linking order for a bit, the build process only gives me one

glfwSetCursorPosCallback to function in another class

问题 I'm really stuck: I have the mainWindow and in the main game loop I do: // poll for input glfwPollEvents(); this->controls->handleInput(window, world->getPlayer()); glfwSetCursorPosCallback(window, controls->handleMouse); What I want to do is to have one class responsible for the controls and to have this class also handle the mouse. I always get: 'Controls::handleMouse': function call missing argument list; use '&Controls::handleMouse' to create a pointer to member Now when I try this I get:

GLFW Undefined References

人盡茶涼 提交于 2020-01-11 09:25:11
问题 I'm trying to use GLFW on a project, but when I compile it, I get a lot of undefined reference errors, while many of them is on the library file (libglfw.a). I tried both, compile the library and download it, but without success. I'm using MinGW and MSYS running on Windows 7 32-bits on netbeans. The GLFW version is 2.7.3; These are the errors: "/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf make[1]: Entering directory `/c/Users/Raphael/Documents/NetBeansProjects
