Points are easy to move.

Vector3d vectemp = boids[i];

Point3d pttemp = agenci[i];

pttemp += vectemp;

or

agenci[i] = agenci[i] + boids[i]

Thanks!

But how with other geometry? Crvs, breps etc.?

Point3d and Vector3d are not like other types of geometry, but it tends to work in roughly the same way everywhere. Transformations can be applied using the RhinoCommon Transform matrix type. A transform matrix is usually used in conjunction with a Transform method:

Transform motion = Transform.Translation(vectorMotion);

Point3d point = ...;

point.Transform(motion);

the last line will modify the point.
