go3d is a performance oriented vector and matrix math package for 2D and 3D
Every type has its own sub-package and is named T. So vec3.T is the 3D
For every vector and matrix type there is a String() method and a Parse()
Besides methods of T there are also functions in the packages, like
Packages under the float64 directory are using float64 values instead of
Matrices are organized as arrays of columns which is also the way OpenGL
DirectX expects "arrays of rows" matrices, use the Transpose() to convert.
Methods that don't return a specific value, return a pointer to the struct
to allow method call chaining.
a := vec3.Zero
b := vec3.UnitX
Method names in the past tense return a copy of the struct instead of a
pointer to it.
a := vec3.UnitX
b := a.Scaled(5) // a still equals vec3.UnitX
