Particle Flow Tools:
Box #3
With the development of the new particle data visual scripting interface Data
View, and addition of 20+ sub-operators, the plug-in brings to special effects
artists powerful and flexible tools to design their own operators and tests in
Particle Flow.
Particle Flow Tools: Box#3 includes the following
new operators and tests:
Data Operator is the main operator of the
package. 'Edit Data Flow...' button opens Data
View - the main interface to manipulate the particle properties and data.
Data Icon is a variation of the Data
Operator that has visible 3d icon in the viewport, and has an extra sub-operator
Icon that a regular Data Operator does
not have.
Data Preset operator works as a shortcut
to the list of presets that were saved with the data operators. The list
includes only the presets that were made with either Data Operator or Data Icon.
Data Test is similar to the Data Operator
but in the form of a test. It has an extra sub-operator
Output Test that a regular Data Operator
does not have.
Data Icon Test is a data test with an
icon. It has access to all data sub-operators.
Data Preset is a test version of the Data
Preset operator. The list of this Data Preset includes only the presets that
were made with either Data Test or Data Icon Test.
Cache Selective is a cache operator with
the option to exclude some particle properties from caching. The overall cache
size can be significantly reduced by excluding the Shape data. To make up for
the absence of some properties in the cache, a Cache Selective operator has an
option to run operators in a post-cache process.
Cache Disk operator is similar to the
Cache Selective operator but with the option to keep the cache data on the disk
on a file-per-frame basis.
Data Display shows, in the viewport,
numerical data created by a Data operator or test.
Besides the operators, Box#3 includes numerous sub-operators that can be wired
together in Data View to define particle data flow in a Data operator -
Amount Change,
Condition,
Convert,
Function, Geometry,
Icon,
Input Custom, Input Proxy,
Input Standard,
Notes,
Object, Output Custom,
Output New,
Output Standard,
Output Test,
Parameter,
Particles,
Pipe,
Random, Scalar,
Select Object,
Switch, and
Vector.
Examples:
Here's an example that was used for testing 'Prevalent
Custom Data' option in Particles
sub-operator:
Animation - GrowSpread.zip (6.37MB)
The 'Prevalent Custom Data' option gives
the ability to test a custom data channel from the surrounding particles (or
other particle systems). The scale grow of particles is initiated by two
factors: proximity to a reference object (the sphere), and the scale factor of
the surrounding particles. As a result, movement of the sphere creates the
initial seeds of grow; and these seeds initiate the scale grow in the
surrounding areas.
The example illustrates the abilities of Box#3 to add the rule-based elements to
the event-based Particle Flow particle systems - there is a single event with
two Data operators. The first custom Data operator 'Particle Per Vertex'
generates new particles to match the knots in a grid; the second Data operator
controls the scale grow of the particles. Besides
Particles, the data flow uses other
sub-operators - Condition,
Convert,
Function, Input Custom,
Input Standard,
Object,
Output Custom, Output New,
Scalar, and
Select Object.
This example shows how Box#3 can force
different PFlow particle systems to work in unison and to exchange data:

Also, the example illustrates how it is
possible to design particle systems with
history-independent properties that can significantly speed up the
calculation time and feedback interactivity.
