OpenGL and GLUT in Eclipse on OS X

由 爷，独闯天下 提交于 2019-11-27 06:50:51
问题 I have been trying to setup the OpenGL and GLUT libraries in Eclipse, with CDT, on OS X with not very much success. I cannot seem to get eclipse to actually realize where GLUT is. It is currently giving me the error that I have an unresolved inclusion GL/glut.h. Looking around online I found that I should be using the -framework GLUT flag in the gcc linker settings, but this seems ineffective. 回答1: Ok. I got it working in X11. The reason I could only get it working on X11 is because it seems

How do you install GLUT and OpenGL in Visual Studio 2012?

由 醉酒当歌 提交于 2019-11-27 06:19:13
I just installed Visual Studio 2012 today, and I was wondering how can you install GLUT and OpenGL on the platform? dlivi OpenGL should be present already - it will probably be Freeglut / GLUT that is missing. GLUT is very dated now and not actively supported - so you should certainly be using Freeglut instead. You won't have to change your code at all, and a few additional features become available. You'll find pre-packaged sets of files from here: http://freeglut.sourceforge.net/index.php#download If you don't see the "lib" folder, it's because you didn't download the pre-packaged set.

OpenGL - Mouse coordinates to Space coordinates [closed]

由 本小妞迷上赌 提交于 2019-11-27 03:42:37
问题 My goal is to place a sphere right at where the mouse is pointing (with Z-coord as 0). I saw this question but I didn't yet understand the MVP matrices concept, so I researched a bit, and now I have two questions: How to create a view matrix from the camera settings such as the lookup, eye and up vector? I also read this tutorial about several camera types and this one for webgl. I still can put it all together I don't know how to get the projection matrix also... What steps should I do to

问题 This question already has answers here : What is an undefined reference/unresolved external symbol error and how do I fix it? (32 answers) Closed 4 years ago . I try to compile some "hello world" glut application: #include <stdlib.h> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> GLint Width = 512, Height = 512; const int CubeSize = 200; void Display(void) { int left, right, top, bottom; left = (Width - CubeSize) / 2; right = left + CubeSize; bottom = (Height - CubeSize) / 2; top

How to apply texture to glutSolidCube

由 风格不统一 提交于 2019-11-27 01:38:02
问题 I can find tutorials about mapping textures to polygons specifying vertices etc. but nothing regarding how to apply a texture to a cube (or other stuff) drawn with glut (glutSolidCube). I am doing something like: glTexEnvfv(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, decal); glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, repeat); glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, repeat); glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, nearest); glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE

Opengl drawing a 2d overlay on a 3d scene problem

由 时间秒杀一切 提交于 2019-11-26 22:51:49
问题 I have a moving 3d scene set up, and I want to make a stationary 2d GUI overlay that is always on top, when I try making 2d shapes I don't see anything. When I call: glMatrixMode(GL_PROJECTION); my 3d scene disappears and I'm left with a blank window... here is the code I'm using for the overlay EDIT: updated code glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluOrtho2D(-100, 100, -100, 100); glDisable(GL_DEPTH_TEST); glDisable(GL_CULL_FACE);

How to create a class to wrap GLUT?

由 三世轮回 提交于 2019-11-26 22:08:41
问题 I'm writing a game for school in OpenGL. Since there will be several more similar assignments I want to make a small framework for doing common things in OpenGL. I have made a few simple games before and I usually break it down into an IO class to handle input and drawing to the screen, Game class for the main game loop/logic, and classes for whatever objects there are in the game. Before I was using SDL, so my question is, is this the right way of going about this in OpenGL? I've already ran

Segmentation Fault before main() when using glut, and std::string?

由 久未见 提交于 2019-11-26 20:24:17
问题 On 64-bit Ubuntu 14.04 LTS, I am trying to compile a simple OpenGL program that uses glut. I am getting a Segmentation Fault (SIGSEV) before any line of code is executed in main; even on a very stripped down test program. What could cause this? My command line: g++ -Wall -g main.cpp -lglut -lGL -lGLU -o main My simple test case: #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> #include <string> #include <cstdio> int main(int argc, char** argv){ printf("Started\n"); std::string

Glut deprecation in Mac OSX 10.9, IDE: QT Creator

由 丶灬走出姿态 提交于 2019-11-26 17:47:52
问题 I was trying to build an opengl program on qt creator, installed on my mac, with osx 10.9. I got several warnings on glut functions about its deprecation in osx10.9, a sample error message is like: 'glutInit' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] glutInit(&argc, &argv); ^ I wonder if GLUT.h is not usable anymore in osx10.9? According to some other posts, it is said that as long as we change "OS X Deployment Target" back to OSX10.8, then it works. How to do
