REFRAKT_
Refraction that behaves like light through glass.
10 lens-light refraction effects. Kaleidoscope, halo, prism, split mirror. Metal GPU. Not a stamp on top of the image.
One-time purchase. No subscription. No account.
The qualm
Most refraction filters are stamps. Light through glass is not a stamp.
Off-the-shelf refraction effects drop a fixed shape onto the frame. The image underneath is untouched. The result reads as an overlay because that is what it is.
Refraction in real glass redistributes image energy. Pixels bend, split, and reform along the geometry of the lens element. REFRAKT_ models that behaviour. The image becomes the refraction, not the substrate beneath it.
10 Effects
Each one is its own optical model.
Not presets layered on a single shader. Ten distinct refraction models, each solving its own optics. Pick one, push the intensity, get a coherent result.
Linear Prism
Spectral split along a directional axis. Light separated by wavelength.
Kaleidoscope
Symmetric reflection patterns. Configurable segment count and rotation.
Halo
Annular light wrap around the frame centre. Soft, breathing falloff.
Split Mirror
Twin-mirror reflection along an arbitrary plane. Hard or soft seam.
Linear Glass
Striated refraction with phase-shifted bands. The look of looking through textured glass.
Focal Wedge
Anamorphic-style flare wedge driven by focal compression. Directional.
All 10 effects in v1.0: Linear Prism · Kaleidoscope · Halo · Split Mirror · Linear Glass · Focal Wedge · Starburst · Chromatic Streak · Diachronic Crystal · Freeform Prism.
Under the hood
Metal GPU. Real-time. Per-effect optical models.
Apple Metal
Native GPU compute. Each effect ships as its own kernel. Zero-copy buffer pipeline.
Image-conserving
Refraction redistributes pixel energy. Highlights bend, shadows fold. No overlay layer sitting on top.
Full bit depth
32-bit float throughout. Precision-critical at high refraction angles where banding shows fastest.
Per-effect parameters
Each effect exposes the controls that matter for its model. Not a generic slider stack.
Privacy
Offline. Always.
REFRAKT_ runs entirely on your GPU. No internet connection. No telemetry. No accounts. No cloud rendering. Your footage stays on your machine.
Safe for NDA work. Nothing leaves your system.
