Classic sine plasma with a cosine palette
In your harnessGodot shaderMIT
Animated plasma: four sine fields (horizontal, vertical, diagonal and radial) summed and mapped through a cosine colour palette that cycles over time.
What it takes and gives
- Shader type
- canvas_item
- Parameters
- scale (float = 8), speed (float = 1), palette_offset (vec4 = 0.5, 0.5, 0.5, 1), palette_amplitude (vec4 = 0.5, 0.5, 0.5, 1), palette_frequency (vec4 = 1, 1, 1, 1), palette_phase (vec4 = 0, 0.33, 0.67, 1), cycle_speed (float = 0.15), color_steps (int = 0)
- Use it on
- A ColorRect (or any CanvasItem) sized to the area to fill; UVs span 0 to 1 across it.
- Result
- Smoothly flowing rainbow bands that swirl around a wandering centre.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/plasma_sine_2d/
Limits. Pure function of position and time: no texture detail. Palette parameters outside 0..1 can clip.
