| double precision function | mod_geo_tools::compute_cos_angle (v1, v2) |
| | Compute the cosinus of the angle between two vectors v1 and v2.

| double precision function, dimension(3) | mod_geo_tools::find_position_sphere (x, orig, dist, normal, x_radius, min_cos_angle, effective_cos_angle, is_debug) |
| | Find the position of the point in the surface with spherical approximation.

| double precision function, dimension(3) | mod_geo_tools::restrain_descent (x1, x2, max_step) |
| | Restrain the advance from x1 towards x2 up to max_step.
|
| |
| double precision function, dimension(3) | mod_geo_tools::compute_best_point_with_angles (x1, theta1, x2, theta2) |
| | Return the interpolated point between x1 and x2, given respective angles by linear interpolation between theta1 and theta2. In practice, compute the interpolation parameter \( \alpha \in [0,1]\) such that \( \theta( \alpha ) = \theta_1 + (\theta_2 - \theta_1) \alpha \). We search for \( alpha = 0 \). Finaly, the result is \( X(\alpha) = X_1 + \alpha (X_2 - X_1) \).
