hydra reference
An interactive reference for the hydra video synth. For each parameter: what it means, its useful range and units, which value turns it off, what negative values do, and a sweep of rendered frames showing the effect.
oscSine-wave stripes: frequency, sync, and color offset.
rotateTurning the image; radians, direction, aspect shear.
scroll · scrollX · scrollYMoving the image, and why scroll always wraps.
colorPer-channel multiply, and what negative values do.
modulateDisplacing one texture by another texture's colors.
Array modifiersfast, smooth, ease, offset, fit: sequences over time.
