1. An apparatus for generating a three-dimensional object, the apparatus comprising:
an energy source to apply energy to a layer of build material to cause a first portion of the layer to coalesce and solidify;
a first agent distributor to selectively deliver a cooling agent onto a second portion of the layer;
a second agent distributor to selectively deliver coalescing agent onto the first portion of the layer; and
a controller programmed to:
control the second agent distributor to selectively deliver the coalescing agent onto the first portion of the layer to cause the first portion to coalesce and solidify in a first pattern when the energy is applied;
control the energy source to apply energy to the layer to cause the first portion to coalesce and solidify in the first pattern; and
control the first agent distributor to selectively deliver the cooling agent onto the second portion of the layer in a second pattern, the first and second patterns being independent of each other.
