Why should we link OpenGL libraries? I am using Visual C++ 6.0, I was told to inlcude OpenGL32.lib GLu32.lib glut32.lib into Project/Settings. But, my program works. Hi all, I am learning glut because most book uses it. 1.When we write opengl program, do we need opengl32.lib, glu32.lib, glaux.lib? Where could we dow. The problem is that linker cannot find an opengl32.lib file. Try to find it under VC2013. Make sure that the path to it is included in additional library paths. With thanks to Kamil Saykali of the EdCenter. Opengl32.lib glut32.lib glu32.lib. Chose 'OK' and that will include all the opengl libraries that you need.

I never include #pragma (I don't know what it is as well), and I am using pure OpenGL function, just really confuse. I program OpenGL using Window Console Application, after I have compiled and build the file, I go to my Project Settings/Link, the libraries shown are: kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib As you may see, the program works fine even without including any OpenGL libraries.

Or may it be the case where the OpenGL libraries are included once, and need not to be included at the subsequent time? I just want to know whether you all include those OpenGL libraries 'each time' you create a new project, or incluce it once, and no need to include it again next time when creating a new project? Convert File Names To Uppercase Windows here. Or OpenGL libraries are not necessary for console application? Someone correct me if I'm wrong, but the libraries is what ties the executables with your source code.

You're calling a library function, any function. The compiler will need the library file so it can find the address of the function in the dll file. My guess is that the compiler you're using knows where to find the.lib's A couple of years ago when I started learning OpenGL this thing had me fumbled for 4 days, as I used an glaux function and my project could not link to the auxiliary library. In the end, know that the thing happens, even if it is done automatically, and you don't know about it. PS At least you know what to do if your compiler start spitting link errors. I will not reply by today if I am buzy because I am rushing my OpenGL assignment and for another two hours more, it is the assignment deadline.

What make ridiculous is that there is one last part remaining, that is I don't know how to transform a straight line to a curve line upon animation. I know it is not fair to me ask for help for my assignment, but I just want to know is there any OpenGL API function which can transform straight line to a curve line? For library linking issues, I hope that we can discuss further later. Now my time here is 05:14am.

Ok, after a whole days searching, i managed to find the latest GLU 1.3 lib and dll. No more linking errors, but there is a memory access fault. Any solutions?? One more question, does gluBuild2DMipmaps create texture objects for each of the MIPMAPS it generates from the base texture? I basically wanted to conserve some memory thinking that it does, and if someone wanted to run my app.

On a graphics card with lower mem, i thought it would improve performance by making the lower res. Textures resident and avoiding the extra higher res. So was the assumption right or wrong?? Also the redbook had gluBuild2DMipmapLevels listed in it (OpenGL v1.1).

Well, im not sure if it is actually part of it or not. If not, can i access it by using extensions as in requesting the runtime proc. Address of the function in my driver if it is actually supported by the driver?? There is an extension for generating mipmaps which is a lot better than gluBuild2DMipmaps, SGIS_generate_mipmaps, which does this hardware accelerated, and also, the glu function has a bug (maybe you just discovered that bug, sometimes it crashes), which is also avoided by this. I would guess that the glu function as well as the sgis extension creates one texture image for each mip mapping level, just as creating them manually (which is what glu. If you want to avoid the highest resolution mipmap level it's easiest to start with a lower res base texture. Cadex Battery Shop Manual.

Check the amount of graphics memory and if you find it is not enough, simply scale down the texture when loading and creating the texture image.

Well, i dont know if gluBuild2DMipmaps has a bug or not, caz I've been using that for quite some time now on 2 NVIDIA cards and it never did crach for me.
