Gradient

A pure generator that produces an angled gradient. The gradient is turned into a triangle wave, so the color does not jump at the band boundaries.

• Angle — the direction of the gradient (degrees). 0–360, default 0
• Bands — the number of stripes across the screen. 1–16, default 1
• Scroll — how many bands it advances per cycle. 0–1, default 0 (= stopped)
• ColorA / ColorB — the two colors
• Speed — how many cycles per second
• Seed — not used by this shader

The output resolution is chosen from the dropdown on the node, from FullHD / HD (default) / SD.

Phase uses an external value only when it is connected; when it is not, the fractional part of the internal time (a 0→1 sawtooth) is fed in. Since Phase is a sawtooth, the position jumps at the wrap unless the advance per cycle is a whole number of bands. So Scroll × Bands is rounded internally and quantized to whole bands, making the loop close exactly in one cycle (a design intended for tempo sync).
