orx-temporal-blur

orx-temporal-blur

Post-processing temporal-blur video effect. CPU intense, not intended for real-time uses.

If using ScreenRecorder make sure to enable the frameClock and frameRate in its properties. This will make seconds be based on the current frame count instead of the real time.

This extension uses multi-sampling to accumulate and average the final image.

Multi-sampling is performed by modifying Program.clock while processing the tail-end of the extension chain. This multi-sampling strategy is slow and not entirely suited in real-time and/or interactive settings.

orx-temporal-blur works well with programs that use seconds for their animation input.

Note that time-step-based simulations or integrations will likely break because your drawing code will be executed multiple times per frame.

Configuration

extend(TemporalBlur()) {
    duration = 0.9 // duration is in frames
    samples = 30 
    fps = 60.0 
    jitter = 1.0
}

Color shifts

Additionally, a color matrix can be set per accumulation step. See DemoColorShift01.kt

extend(TemporalBlur()) {
    colorMatrix = {
        // `it` is 0.0 at start of frame, 1.0 at end of frame
        tint(ColorRGBa.WHITE.mix(ColorRGBa.BLUE, it))
    }
}

Demos

DemoBasic01

A minimal demonstration of TemporalBlur.

Each animation frame will be rendered 10 times sampling and mixing 0.9 seconds of animation.

source code

DemoColorShift01

A more advance demonstration of TemporalBlur, showing how a function can be used to apply a varying colorMatrix transformation across the sampling duration.

This example makes the samples fade from white to blue in each frame.

The gain parameter is used to increase the brightness of the resulting pixels.
