Vector constants for specific dimensions. More...

Detailed Description

Vector constants for specific dimensions.

It is preferable to use these constants rather than constructing them when they're required. Construction most-likely slower than loading them from memory.

For example, the following:
lookat = mat4::LookAt(target, position, mathfu::kAxisY3f);
is preferable to:
lookat = mat4::LookAt(target, position, mathfu::Vector<float, 3>(0.0f, 1.0f, 0.0f));
in terms of efficiency and in addition to resulting in more concise code.

Depending on your linker's sophistication and settings, these constants may be duplicated in every compilation unit in which they're used. However, most linkers should be able to detect and eliminate this duplication.
