Rotate a mesh around an axis — rotate_mesh • scimesh

Rotate a mesh around an axis

Usage

rotate_mesh(mesh, angle_rad, axis = c(0, 0, 1))

Arguments

mesh: A mesh descriptor list.
angle_rad: Rotation angle in radians.
axis: Length-3 numeric vector defining the rotation axis.

Value

A new mesh descriptor list with rotated vertices.

Examples

mesh <- generate_cuboid(c(0, 0, 0), c(1, 1, 1))
rotated <- rotate_mesh(mesh, pi / 4, axis = c(0, 1, 0))
rotated$vertices[1, ]
