This compound orients particles in the direction of a vector that you choose. This is useful for setting up anything that
needs a specific orientation relative to another scene element, such as the surface normals of an object.
Plug this compound's Execute output into a Port on the ICETree node.
For more information, see Aligning Particles to a Vector [ICE Particle Simulations].
Tasks: Particles/Orientation
Output Ports: Execute

The vector that is used to align the particles. The Y axis is typically the vector that points along the length of a particle.
If you change the particle shape to a cone, you can see that the Y axis is the direction of the cone point. The X and Y axes
are the sideways axes.

The vector to which the particle axis you've chosen (Local Vector) is aligned. This could be something like the surface normal
of an object.

Defines how much the particle is rotated each frame. The value is a ratio, so if you set it to 1.0, the particle is immediately
aligned. If you set this value to 0.1, the particle rotates by 10% each frame.
