Transformations

The following transformations can be applied to curves and surfaces.

Scaling

To scale a curve or a surface, the functions scale and scale! are provided.

using NURBS
Patches = readMultipatch("assets/sphere.dat")

scale!(Patches, 2.3) # the sphere of radius 1 has now radius 2.3

Translating

To translate a curve or a surface, the functions translate and translate! are provided.

using NURBS, StaticArrays

shift = SVector(2.4,-1.0,0.5)
translate!(Patches, shift) # move the whole sphere

Rotating

To rotate a curve or a surface around a rotation axis by a given angle, the functions rotate and rotate! are provided.

using NURBS, StaticArrays

rotAxis = SVector(1.0, 1.0, 1.0)
α = π/3

rotate!(Patches, rotAxis, α)

Mirroring

To mirror/reflect a shape through a plane defined by its normal vector and an anchor point, the functions mirror and mirror! are provided.

using NURBS, StaticArrays

normal = SVector(0.0, 1.0, 0.0)
anchor = SVector(0.0, 0.0, 0.0)

mirror!(Patches, normal, anchor) # mirror through the xz-plane
