Lava lamp metaballs
In your harnessGodot shaderMIT
Soft blobs that merge and split like a lava lamp: several metaballs follow Lissajous paths, their summed inverse-square field is thresholded into shapes, shaded by the field gradient and given a glowing rim.
What it takes and gives
- Shader type
- canvas_item
- Parameters
- blob_color (vec4 = 1, 0.35, 0.25, 1), highlight_color (vec4 = 1, 0.85, 0.45, 1), background_top (vec4 = 0.2, 0.05, 0.3, 1), background_bottom (vec4 = 0.45, 0.08, 0.25, 1), blob_count (int = 7), blob_size (float = 0.06), threshold (float = 1), speed (float = 0.4) and 1 more
- Use it on
- A ColorRect (or any CanvasItem) sized to the area to fill; UVs span 0 to 1 across it.
- Result
- Orange blobs with yellow highlights flowing and merging over a purple gradient.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/metaball_blobs_2d/
Limits. Cost grows with blob count times three field evaluations per pixel. Blobs are 2D: no occlusion or depth.
