PYROCLUSTER

Use Intersection, Ray Bias

A wooden box filled

with smoke, with Use

Intersection disabled (left)

and enabled (right). The

enabled option keeps the

smoke in the box.

Intersection tests are normally used to detect collisions in dynamic simulations.
However, intersection testing also helps to constrain gas or smoke, so enable this
option if you want to, for example, send a gas stream through a pipe. As you might
expect, intersections can take quite some time to calculate for gaseous objects and
a fast processor is recommended.

The Ray Bias value enables you to move the intersection point along the intersection

ray to fine-tune the result. A value of 0 represents the originally calculated point of
intersection; higher values will move the point away from there.
