VC基于单文档OpenGL框架

本文是在VC6.0的环境下，运用MFC实现的OpenGL最基本框架，需要简单了解MFC编程（会在VC6.0里创建MFC单文档应用程序就行），甚至不必了解OpenGL的知识。以下是具体的步骤。 1 、创建 MFC 单文档应用程序 2 、添加 lib Project->Setting->Link 添加 " *.lib " opengl32.lib glu32.lib glut32.lib glaux.lib 以上的 lib文件需要存在于 VC6.0安装好的目录下的 lib文件夹底下，例如： C:\Program Files\Microsoft Visual Studio\VC98\Lib 如果一些lib文件没有，可以去网上搜下，自己下载。 3 、在 stdafx.h 中添加 OpenGL 头文件 // OpenGL Headers #include <gl\gl.h> // OpenGL32库的头文件 #include <gl\glu.h> // GLu32库的头文件 #include <gl\glut.h> // OpenGL实用库的头文件 #include <gl\glaux.h> // GLaux库的头文件 以上的头文件需要存在于 VC6.0安装好的目录下的 Include下的 GL文件夹下，例如： C:\Program Files\Microsoft Visual Studio

light shows but the cube does not appear

问题 I am trying to use lighting on a cube but I don't understand where am going wrong. I can be able to view the light source but the rest of the screen appears black so I don't understand why the cube is disappearing. Here is the code: /*Header Inclusions*/ #include <iostream> #include <GL/Glew.h> #include <GL/freeglut.h> // GLM Math inclusions #include <glm/glm.hpp> #include <glm/gtc/matrix_transform.hpp> #include<glm/gtc/type_ptr.hpp> using namespace std; // Uses the standard namespace #define

Not getting an output for OpenGL to print line using mouse click

由 ￣綄美尐妖づ 提交于 2021-02-16 14:59:07
问题 My aim is to draw a line using mouse click. When you click the first click it reads the coordinates then when for the nest click it will draw the line using GL_LINES with first and second points. int first, x1, yi, x2, yj, ww = 600, wh = 400; void drawl() { glClear(GL_COLOR_BUFFER_BIT); glLineWidth(5.00); glColor3f(0,1,0); glBegin(GL_LINES); glVertex2i(x1,yi); glVertex2i(x2,yj); glEnd(); glFlush(); } void Display() { glClearColor(0.5, 0.5, 0.5, 1.0); glColor3f(0.7, 0.4, 0.0); glClear(GL_COLOR

Display 2D text with freeglut, using OpenGL

由 懵懂的女人 提交于 2021-02-05 09:24:42
问题 I'm pretty new into this and I'd like to display fixed location 2D texts (like level, life, score etc.) on my game's screen which is basically a 3D game. I have found a few similar questions but still could not figure out the solution for me. I mainly use GLFW for everything but I'd like to use glut for displaying texts. I have a funcion (based on a few other questions I've found here) to try out how it works but I'm not sure how exactly can I make it to actually display because now

Why is my OpenGL program unable to load the GLUT bitmap fonts?

由 筅森魡賤 提交于 2021-02-05 08:43:07
问题 I want to display some simple text on the HUD of my 3D environment in OpenGL. All sources say that I should use the bitmap fonts included in GLUT, however, my program can't seem the find/load the fonts. I have included all of the correct libraries and have double checked that the fonts.py file is definitely in the ...\Python37\...\OpenGL\GLUT\ directory, but when I type GLUT_BITMAP_TIMES_ROMAN_24 (or any of the other bitmap fonts), it is highlighted as an error in my code. This is the

Why does my wired sphere turn into ellipsoid when translating and changing camera angle?

由 十年热恋 提交于 2021-02-05 07:58:27
问题 I need to translate my wired sphere along z-axis back and forth while also changing camera angle. Whenever my sphere gets translated, it slowly turns into ellipsoid. I really don't understand why. Here you can see pieces of code where I believe is a mistake. Also, shapes shouldn't be changed when resizing the window, only their size. void init() { glClearColor(0.0, 0.0, 0.0, 0.0); glEnable(GL_DEPTH_TEST); } void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(
