Hydra sources inside Estuary are chained with dot-notation and sent to outputs with .out()

Estuary embeds the Hydra video-synth language (select ‘Hydra’ in a code zone). The syntax is identical to standalone Hydra: start with a source (osc(), noise(), shape(), solid(), gradient(), voronoi()), chain geometry/colour/blend/modulate transforms with dot notation, and route to an output buffer with .out(o0). Multiple buffers (o0–o3) can be rendered simultaneously. render() by default shows all four. Import camera/video/image with initCam(), initVideo(), initImage(). In Estuary, the speed global variable controls playback rate of time-dependent functions.

Examples

osc(60,0.1,0.0).color(1,0,0).out(o0)
noise(10,0.1).modulate(osc(4),0.5).out(o1)
render()

Assessment

Explain the difference between .blend(t, 0.5) and .modulate(t, 0.5) in Hydra, and write an example of each applied to an osc() source.
