Animation

Fractorium offers support for generating animation sequences in the Library tab.

Editing the values below has no effect on the interactive renderer. They are only used when generating a sequence, performing animation or saving to Xml.

Interpolation

The method to use when interpolating flames during sequence generation. Linear uses basic linear interpolation when generating all of the steps between key frames, while Smooth uses log interpolation. The first and last key frames in a sequence must use Linear.

Default: Smooth

Affine Interpolation

The method to use when interpolating affine transforms during sequence generation. Linear uses basic linear interpolation for each coefficient of affines, while Log converts to polar coordinates before interpolating.

Default: Log

Temporal Samples

The number of temporal samples used to blend between sequence frames during animation. Even after a sequence has been generated that produces a number of steps between key frames, when performing the animation render, each of those sequence steps is blended between the surrounding sequence steps. Temporal samples is the number of blended steps between each sequence step that get combined into a single output frame.

Note this value does not change the number of iterations done. Instead, each animation frame divides its total requested iterations by the number of temporal samples, then uses that value for the iteration count of each sample.

Values between 100 and 1000 are often used. Higher values will produce more of a motion blurring effect when animating.

When rendering a single image, this value will always be set to 1 by Fractorium right before rendering regardless of the value set in the UI.

Default/disabled: 1

Temporal Filter Width

The width of the temporal filter used during animation.

When computing the temporal samples to render, boundary frames must be computed to know what to blend between. By default this is just the sequence frames before and after the one currently being rendered. However, the time bounds of what’s being blended can be less than that, or even greater which means it will be blended across several sequence steps.

In practice, this will almost always have its default value of 1.

Default: 1.00

Temporal Filter Type

The type of the temporal filter used during animation. This is similar to the spatial filter in that the type can be chosen to produce different effects.
