Vectors

Meshes.Vec — Type

Vec(x₁, x₂, ..., xₙ)
Vec((x₁, x₂, ..., xₙ))
Vec{Dim,T}(x₁, x₂, ..., xₙ)
Vec{Dim,T}((x₁, x₂, ..., xₙ))

A geometric vector in Dim-dimensional space with coordinates of type T for linear algebra.

By default, integer coordinates are converted to float.

A vector can be obtained by subtracting two Point objects.

Examples

A = Point(0.0, 0.0)
B = Point(1.0, 0.0)
v = B - A

# 2D vectors
Vec(0.0, 1.0) # double precision as expected
Vec(0f0, 1f0) # single precision as expected
Vec(0, 0) # integer is converted to float by design
Vec2(0, 1) # explicitly ask for double precision
Vec2f(0, 1) # explicitly ask for single precision

# 3D vectors
Vec(1.0, 2.0, 3.0) # double precision as expected
Vec(1f0, 2f0, 3f0) # single precision as expected
Vec(1, 2, 3) # integer is converted to float by design
Vec3(1, 2, 3) # explicitly ask for double precision
Vec3f(1, 2, 3) # explicitly ask for single precision

Notes

A Vec is a subtype of StaticVector from StaticArrays.jl
Type aliases are Vec1, Vec2, Vec3, Vec1f, Vec2f, Vec3f
