Rotate Mesh

Rotate Mesh

rotate_mesh(
  mesh,
  angle = c(0, 0, 0),
  pivot_point = c(0, 0, 0),
  order_rotation = c(1, 2, 3)
)

Arguments

mesh

The mesh.

angle

Default c(0,0,0). The rotation amount for the x/y/z axes, in degrees.

pivot_point

Default c(0,0,0). The pivot point of the rotation.

order_rotation

Default c(1,2,3). The order in which to perform the rotations.

Value

Rotated Mesh
