Spherical

Spherical coordinate system represented by an array [radius, phi, theta].

Array Layout​

  • [0]: radius (Distance from the origin)
  • [1]: phi (Polar angle in radians, 0 to PI)
  • [2]: theta (Azimuthal angle in radians, 0 to 2PI)

Function Reference​

Base​

FunctionDescription
spherical_create(radius?, phi?, theta?)Creates spherical coordinates (default: 1, 0, 0).
spherical_set(s, radius, phi, theta)Sets the spherical components.
spherical_copy(s, other)Copies the values of the given spherical to this instance.
spherical_clone(s)Returns a new spherical with copied values from this instance.
spherical_make_safe(s)Restricts the polar angle phi to be between 0.0001 and pi - 0.0001.

Conversions​

FunctionDescription
spherical_set_from_cartesian_coords(s, x, y, z)Sets the spherical components from Cartesian coordinates.
spherical_set_from_vector3(s, v)Sets the spherical components from a Vec3.
vec3_set_from_spherical(vec3, s)Converts from Spherical to Cartesian coordinates (in Vec3 module).
