# OpenGL How do you get the OpenGL libs linked when building in Visual C++?

## Recommended Posts

Hello, I am not new to programming, I do it for a living -- however, I have been using mostly web technologies, java, and straight C++. I AM new to OpenGL and to Microsoft programming. So I am having some real difficulties. My main concern is this: I have an OpenGL game programming book (written by the CEO and COO of GameDev.net) and it conveniently shows how to write a simple windows WGL program to use OpenGL -- but doesn''t really mention the intricacies involved. (I guess they assume you know Visual C++ well. Oops) Anyways, I need to know about what I wrote in the subject email: when I go to BUILD my .CPP file, it gives me many errors regarding UNRESOLVED EXTERNAL SYMBOL for all of the openGL stuff. I KNOW this has to do with linking (otherwise the stuff compiles fine) ... anyone know how to deal with this? Also, if you know of a good crash course online in general for linking and building Win32 / MFC / etc programs, let me know. Thanks!

Go to "Project"->"Settings", and select the "General" category under the "Link" tab. There in the "Object/Library modules" text-box you add "opengl32.lib" and "glu32.lib"

(Sorry if it was to detailed )

Ok, umm... thanks for the info with linking libraries for projects in Visual C++. However, I still get a message about "unresolved external symbol _main"

I assume this has to do with my use of
int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)

Is there another standard windows library that I need to link? The books make no mention of this (I have two Visual C++ books and two game programming books and they all conveniently IGNORE library linking!!)

Hi,
You have choose the wrong Project. You choose Win32-Consoleapplication but you need Win32-Application.

Bye

• Both functions are available since 3.0, and I'm currently using glMapBuffer(), which works fine.
But, I was wondering if anyone has experienced advantage in using glMapBufferRange(), which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.

hi guys,
are there any books, link online or any other resources that discusses on how to build special effects such as magic, lightning, etc. in OpenGL? i mean, yeah most of them are using particles but im looking for resources specifically on how to manipulate the particles to look like an effect that can be use for games,. i did fire particle before, and I want to learn how to do the other 'magic' as well.
Like are there one book or link(cant find in google) that atleast featured how to make different particle effects in OpenGL (or DirectX)? If there is no one stop shop for it, maybe ill just look for some tips on how to make a particle engine that is flexible enough to enable me to design different effects/magic
let me know if you guys have recommendations.

How do we rotate the camera around x axis 360 degrees, without having the strange effect as in my video below?
Mine behaves exactly the same way spherical coordinates would, I'm using euler angles.
Tried googling, but couldn't find a proper answer, guessing I don't know what exactly to google for, googled 'rotate 360 around x axis', got no proper answers.

The video shows the difference between blender and my rotation:

I've had a Google around for this but haven't yet found some solid advice. There is a lot of "it depends", but I'm not sure on what.
My question is what's a good rule of thumb to follow when it comes to creating/using VBOs & VAOs? As in, when should I use multiple or when should I not? My understanding so far is that if I need a new VBO, then I need a new VAO. So when it comes to rendering multiple objects I can either:
* make lots of VAO/VBO pairs and flip through them to render different objects, or
* make one big VBO and jump around its memory to render different objects.
I also understand that if I need to render objects with different vertex attributes, then a new VAO is necessary in this case.
If that "it depends" really is quite variable, what's best for a beginner with OpenGL, assuming that better approaches can be learnt later with better understanding?
