Filter Forge 4.0 Beta 2 released: Node-based loops and recursions!

Hi everyone!

We’ve just released a new beta of Filter Forge 4.0 that introduces fully node-based loops and recursions!

Quote: Loop is immensely powerful: it brings two key concepts of programming – nested loops and recursions – into a visual environment of Filter Forge, in a way that doesn't require you to write any code. Arguably, this is the biggest addition to Filter Forge since version 1.0 in terms of image generation abilities.

However, proceed with caution. At the core of the Loop component lies recursion, a concept adapted from programming languages with all its benefits and hazards (such as potential exponential growth in rendering time). Unlike many other Filter Forge components that produce visible results no matter how you connect them, Loops require a more deliberate approach. That's why we put them into the new Advanced component category, together with Scripts

In programming, a loop is a construct that repeats a certain sequence of commands multiple times, with possible variation from iteration to iteration. Similarly, the new Loop component in Filter Forge lets you render a subtree of components multiple times and combine results of all these iterations into a single output image:

Loops can be nested. In the example below, an inner loop creates a row of 5 circles, which is then duplicated 5 times by the outer loop. Note that slave components of the outer loop can affect components in the subtree of the inner loop:

The Loop component does its work via its slave components: Accumulated, Position, Iteration and Randomizer. You can have multiple slave components linked to a single Loop (except Accumulated, which cannot have multiple copies). The example below uses multiple Randomizers, each with their own color range and Variation (i.e. random seed) for randomizing multiple inputs of the Loop subtree:

Excellent you guys continue to exceed expectations! Congratulations!

Nice to see iteration functions in a Node based system - if you support After Effects one
day this would be even more fantastic
