  We examine the origin of photometrical properties of N-body merger remnants
from the perpective of their orbital content. We show that disc mergers alone
are unlikely to form a boxy-discy dichotomy in isophotal shape, because of the
survival of disc-like orbits even in violent mergers. The shape of the
different orbit families can vary strongly, depending on how violent the merger
was. Minor axis tubes can become boxy and box orbits can be round. However, for
edge-on projections isophotal shape, orbital content and line-of-sight velocity
are well connected.
