Hi.. It's quiet long time since I use OpenGL what is most common GL math library?

 

I downloaded GLM.

 

Is this very common??

 

I'm 3D engine maker so I must use very common library 

 

Thanks

Since there is no official math library for OpenGL like there is for DirectX, I expect that most people either roll their own (my choice) or find an API-agnostic vector math library.

GLM is awesome, I havn't bothered to look for something else. Definately go for it

[Hodgman]

D3D isn't directly tied to a specific math library either. Yes, there is D3DX, XnaMath.h and DirectXMath, which have all been designed by Microsoft to provide math code that works with D3D, but the actual D3D API doens't directly interact with any of them, so it's just as valid to use GLM with D3D, or DirectXMath with GL!

If you'd like something more generic, try CML, http://cmldev.net/

There is quite a lot of them - here is a list of few I've been working with:

One of the most common is probably glm http://glm.g-truc.net/

Another good one is Eigen (Probably most generic out of these) http://eigen.tuxfamily.org/index.php?title=Main_Page

Then there is Sony's vectormath (used in Bullet engine) http://bullet.svn.sourceforge.net/viewvc/bullet/trunk/Extras/vectormathlibrary/include/vectormath/

You might also look into http://sourceforge.net/projects/simdx86/ although it's under LGPL license.

GLM creates its types around the ones used in OpenGL (ie, mat4, vec3, column major order and so on). So its probably the most easy to set up for using directly with OpenGL.

GLM is the most common.  I use GLM, its good library, haven't had any issues with it, and its just headers no .lib files, so very easy to use.

I rolled most of my own math code, but generally ended up mostly with something resembling GLSL mapped to C with SSE intrinsics being used (when available). (if compiled with C++, it adds some overloaded operators and similar, but is primarily a plain C API).

ironically, this is more used in the server-side code, with most of the renderer still using an older and more informal/ad-hoc system based more around raw float arrays and pointers.

Thank you all 3D working fellows

 

I will choice GLM.

 

Thanks others too
