Sounds like you're drawing the cube off-center and then rotating the off-center cube. What you really want is to draw the cube centered with the "camera," then rotate it, and then translate it out so that you can see it (otherwise you'd be inside it :). Of course when you use OpenGL you have to specify transformations BEFORE you draw, so keep this in mind while you code your transformations (glRotate/glTranslate should be sufficient). If you get what you're getting right now, you can *probably* (depends on how you're doing it for the "probably" to work) just switch around your glRotate and glTranslate and make it work.

Okay, I'm just trying to get a little more practice programming 3D with OpenGL and SDL. In Ben's tutorial last semester there was a spinning cube that you could look at using the mouse and arrow keys. I'm trying to change this a bit, and I have a problem. Whenever I move my mouse, it seems to be rotating the cube around me, and that's really not what I want. I just want to "look" somewhere else. I want the cube to stay rotating in it's own original space. Can anyone help? Thanks! Jacob _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.

Yeah, you can use -mno-cygwin to use gcc as a plain Win32 C/C++ compiler. It means you don't depend on Cygwin, but you also no longer can use standard UNIX function calls.

If you have no constructor, a "default constructor" is created implicitly.
class A {
public:
void method();
private:
std::string mString;
};
delete new A();
A().method();
A a;
a.method();
etc. etc.

Out of curiosity, what OpenGL 1.3 features do you need? (What about OpenGL 1.4? Does that work on Linux?) Since your standard nvidia or ATI card does support OpenGL 1.3 on Windows, one solution to your problem is to treat the new functions as extensions and use wglGetProcAddress (see MSDN) to get them. You may want to look around on developer.nvidia.com or ATI's developer page to see if they have an updated SDK.

Ok, I found out this morning that Microsoft Visual C++ [both 6 Enterprise, and .NET] only have OpenGL 1.1 headers/libraries!!!!!!! Same with Metroworks Codewarrior! I have barely gotten started on the OpenGL renderer for OpenPrivateer and I already forsee needing OpenGL 1.3 features, which are available to me on Linux. Do any of you know of any win32-native compilers that support OpenGL 1.3? Or am I going to have to *shudder* learn DirectX and maintain two rendering APIs -- Derek "Kazan" Meek |

I had tried this before but since I had declared extern HWND hWnd=NULL; in the .h file I got a variable redeclaration compile error in the .cpp file. So moved the =NULL part into the .cpp file and all is well. Thank you!!! Jon |

Hi People, I've been knocking this around for awhile so I thought I'd see if any of you can see any obvious errors with this code I'm working on. I'm using Win32 code for handling the OpenGL window. As some of my routines have gotten long I wanted to split the WinMain.cpp (containing the Game loop, rendering routine, startup, shutdown, etc.) into different files. All I've done so far is put all the #includes, #defines, Windows handles, and function declarations into a file called WinMain.h and #include "WinMain.h" in WinMain.cpp. BUT, WinMain.h is also included in one of my other header files (3DModel.h). When I compile I get the link errors: 3DModel.obj : error LNK2005: "struct HWND__ * hWnd" (?hWnd@@3PAUHWND__@@A) already defined in WinMain.obj I'm confused because I used a code example off GameTutorials.com and he does exactly what I have described here and it works fine. Any clues?? Thanks, Jon Here's what the declarations basically look like:: WinMain.h --- #ifndef _WINMAIN_H #define _WINMAIN_H #include <windows.h> #include <stdio.h> #include <stdlib.h> .... extern HDC hDC=NULL; extern HGLRC hRC=NULL; ... int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow); LRESULT CALLBACK WndProc( .... ... #endif WinMain.cpp --- #include "WinMain.h" #include "3DModel.h" ... 3DObject.h -- #ifndef ..... #include "WinMain.h" .... #endif 3DObject.cpp --- #include "3DObject.h" |

If I want to use gmtl::slerp(...) What do I need to include in order to get it to compile, currently I include QuatOps.h. But that doesn't seem to help. The error I get on compile is src/GameState.cpp:79: no matching function for call to `slerp(gmtl::Quatf&, double, gmtl::Quatf&, gmtl::Quatf&) I believe this is because QuatOps is included earlier, so how do I get around this problem? Thanks Josh |

Guys, The registration to become a CA for the 2003 Game Developer's Conference is on the web now. The GDC will be from March 4 - March 8. If you missed Josh Brown's or my talk on the GDC, it's a great opportunity to learn a lot about the game development industry, about making games, and to meet a lot of people in the industry. The URL is http://www.gdconf.com/volunteers Don't miss out on it! Johnathan |

Maybe it's time to have Ben teach us how to use gltext in a lab? :) There are a couple projects out there that help you render text in OpenGL. gltext is one. (http://gltext.sf.net) I can't think of any of the others off of the top of my head right now.

I just released version 1.9.1 of my audio library, Audiere. You can download it at http://audiere.sf.net/ Here is the change log since 1.9.0: - added GetSupportedFileFormats for file format enumeration - added audiere-config script which provides version information and external library dependencies - finer synchronization granularity on DirectSound output streams for lower-latency OutputStream calls - increase priority of Audiere update thread on all platforms but Win9x, which deadlocks - MP3 support via splay's mpegsound (thanks to Chad Austin and Jacky Chong) - read 10 MP3 frames for smoother playback on corrupt (?) files - added ClassPtr convenience typedefs so people can use them instead of RefPtr<Class> - the configure script outputs the URLs for required libraries if it can't find them - FLAC support (thanks to Chad Austin and Jacky Chong) - added the SoundEffect convenience class for simple sound playback - added menu item to close wxPlayer so you can close child windows in wxGTK - added pitch shifting to the OutputStream interface - added square wave generation - added white noise generation - added pink noise generation - updated wxPlayer |
