VectorMath vs LinearMath?

[thecheeselover]

Hello,

I'm new to bullet physics and I would appreciate some directions. When should we use VectorMath vs when should we use LinearMath? I would actually like to only use VectorMath, as it is more convenient for me. It has a matrix4x4 class and a vector3 class that doesn't have a w component unlike LinearMath classes. Also, there are three directories in VectorMath that have similar header files: neon, scalar, and sse. Should I use vmInclude.h instead or I need to use the headers directly?

Thank you for your precious time,

We never got into using Vectormath properly, and mainly stick to btVector3,btQuaternion and btTransform inside Bullet.

Of course you are free to use any math library in your own code.
