Bubbles

This compound lets you create bubbles like the kind that you used to blow when you were a kid. Noise is used to add realism to the bubble movement.

Plug its Execute output into a port on the ICETree node.

You can also choose Particles Create Particles Bubbles from the ICE toolbar and then pick an emitter object to create bubbles using this compound.

Tasks: Particles/Presets

Output Ports: Execute

Emitter	Plug in the geometry from which you want to emit particles. This must be a geometry with a surface. You can plug multiple geometries into this emitter.
Size	Defines how large the particle is. This value is the particle radius, but the particle display size is the diameter. For example, if the Size value (radius) is 1, the diameter (display) size is 2. See ICE Particle Size [ICE Particle Simulations] for more information.
Bubble Size	The base size of the particle radius. This is used as the mean value around which the Variance Size is calculated in order to create randomly-sized bubbles For example, if this value is 2 and the Variance Size is 1, the random value possibilities would be any size between 1 and 3.
Variance Size	The amount of variation of the randomness on either side of the Bubble Size.
Directional Factor	Sets the speed of the Perlin noise. The initial speed of the particles is overridden by this value.
Perlin Factor	Perlin noise has spatial coherence, meaning that several different points in roughly the same location in space tend to have similar noise added to them. It interpolates between the random values. This allows for the creation of particle "streams" within a noise field. Perlin noise can help make objects more natural-looking by imitating the controlled random appearance of elements found in nature; that is, there is structure to the noise while still appearing fairly random.
Time Frequency	The speed at which the Perlin noise evolves over time.
