Birth Grid makes it easy to create three-dimensional, non-interpenetrating particle arrays. Options include regular or non-uniform grid layout, randomized layer heights, and restricting particle placement to replicate the shape of a mesh object such as a teapot.
Birth Group replicates any arrangement of mesh objects as particles, retaining the original layout, shapes, and materials. For example, you can model a brick building and then convert the whole thing to particles with a few clicks, ready for demolition with the wrecking ball.
Birth Stream combines standard Birth operator functions with position settings and overlap-prevention controls to make sure new particles don't overlap with existing ones, thus preventing inadvertent collisions.
