How to build or install freeglut on a windows machine

由 ♀尐吖头ヾ 提交于 2019-12-10 10:44:03
问题 I downloaded freeglut. I'm reading the installation instructions. I extracted all the files. I see a file called configure (and configure.ac). I opened visual studio command prompt and changed the directory to C:\DevStuff\OpenGL\freeglut-2.8.0 The next step is to configure the packages ./configure This looks like a Linux command. How am I supposed to complete this kind of a build on a windows 7 machine? I have visual studio 2010 ultimate ed. UPDATE I found the VS2010 directory and

Trouble with vsync using glut in OpenGL

由 拟墨画扇 提交于 2019-12-10 00:03:20
问题 I'm struggling desperately to get Vsync to work in my OpenGL application. Here's the vital stats: I'm using Windows, coding in C++ OpenGL and I'm using FreeGLUT for my OpenGL context (double buffering). I'm aware that for the swap buffer to wait for vertical sync in Windows you are required to call wglSwapIntervalEXT(). My code does call this (as you'll see below), yet I am still getting vertical tearing. The only way I've managed to stop it is by calling glFinish() which of course has a

问题 im on mac os snow leopard gcc 4.5.4 | gcc 4.2.1, trying to build the tutorials http://www.arcsynthesis.org/gltut/ one needs to build dir glsdk first. I install freeglut (prerequisite) via macports freeglut @2.8.0_1 (active) and manually copy and paste its lib and include folders in dir glsdk so that ls ..../Tutorial_0_3_8/glsdk/freeglut -> include lib (I couldn't build the freeglut provided that's why I replace it with the one from macports) after fixing many errors (mostly due to legacy

freeglut - a smooth camera rotation using mouse

由 人走茶凉 提交于 2019-12-08 12:52:29
When I rotate my fps camera using mouse the animation is not smooth. When I use a keyboard everything works nice. For keyboard I use an array of type bool to buffer keys. What Can I do to make the animation smooth when using mouse ? void MousePassiveMotion(int x, int y) { int centerX = glutGet(GLUT_WINDOW_WIDTH) / 2; int centerY = glutGet(GLUT_WINDOW_HEIGHT) / 2; int deltaX = x - centerX; int deltaY = y - centerY; if(deltaX != 0 || deltaY != 0) { heading = deltaX * 0.2f; pitch = deltaY * 0.2f; glutWarpPointer(centerX, centerY); } } Sometimes when the mouse polling rate and the screen refresh

问题 I want to check for Key-Events like pressing up / pressing down ... But the function, which I created to be called, gets a "unsigned char". I am able to check for keys like W/A/S/D with key == 'w' , but I don't know how to check for other keys. Is there any list of available chars, like "\n"? 回答1: You can find a list of character escape sequences here. Note that some keys have to be handled using glutSpecialFunc() / glutSpecialUpFunc() , for whose handler the following applies: The key

Visual Studio 2015: v120 vs v140?

由 落爺英雄遲暮 提交于 2019-12-07 08:10:33
问题 FYI: Win10, x64 I started trying out Visual Studio 2015 today, and after figuring out how to get the C/C++ parts running I tried to load up a big personal project that uses the unofficial glsdk. I tried to build and got linker errors. It complained about unresolved external symbols being referenced in freeglutD.lib, glloadD.lib, and glutil.lib. It also complained about _MSC_VER mismatches in my own files. I did some research online, messed around with 2013 and compiler versions (project

Is it possible to build FreeGLUT on Mac OS X?

问题 I'm doing some tutorials on OpenGL that use FreeGLUT. Apparently this is how you build and install it on the mac: CPPFLAGS="-I/usr/X11R6/include" ./configure --prefix="${PWD}/../" make make install Unfortunately this on its own gives me an error when I do the make command: Undefined symbols for architecture x86_64 After doing abit of work I've found that an improvement on the first line is: CPPFLAGS="-I/usr/X11R6/include -L/usr/X11R6/lib" LDFLAGS="-L/usr/X11R6/lib" ./configure --prefix="${PWD

NetBeans with C++ and OpenGL / Freeglut under Windows 7

由 ℡╲_俬逩灬. 提交于 2019-12-06 14:18:02
I recently tried to figure out how to use freeglut with NetBeans 7. I Google'd a lot and I didn't find a suitable tutorial on how to bind the stuff I need into it. Currently I have more problem then this: First one is: - freeglut 2.8 => in order to compile it I need MinGW and msys. I have both installed but I can't "configure" or "make all" and "make install" freeglut. I didn't find an easy-to-read how-to for that task. Next one: - once built, where to put what files into a specific folder? Last one: - Once put the files into corresponding folder, how to use finally freeglut under NetBeans 7
