Simple three-dimensional vectors of doubles with basic vector and matrix operations, supporting Data.Vector.Unboxed and Data.Vector.Storable.

>>> let v1 = (-1, 0.0,  0.2) :: TVec3
>>> let v2 = ( 1, 2.3,  5.0) :: TVec3
>>> let v3 = ( 1,   1, -0.2) :: TVec3

-- Add two vectors:
>>> v1 <+> v2
(0.0, 2.3, 5.2)

-- Dot product:
>>> v1 .* v2
0.0

-- Multiply by a scalar:
>>> v1 .^ 5
(-5.0, 0.0, 1.0)

-- Cross product:
>>> v1 >< v3
(-0.2, 0.0, -1.0)

-- Matrix-vector product:
>>> diag 2 `mxv` v2
(2.0, 4.6, 10.0)

Please consult the Hackage page for simple-vec3 for full documentation.

The package provides two different implementations for Vec3 type class, which differ in storage scheme. Benchmarks are included for both. You most likely want to use CVec3 which is based on contiguous storage scheme and offers the best performance.

Alternatives

This package was written to explore and benchmark different array storage schemes in Haskell, as supported by vector library. Several alternatives with more extensive APIs exist:
