Radial Blob
Arranges smooth, bulging blobs in a regular U x V grid across the surface. Each blob has a metaball-like falloff that creates organic bumps — like bubble wrap, tactile dots, or a surface covered in soft hemispheres.
Parameters
Amplitude- Blob peak height in mm (0–20). Controls how far each blob protrudes from the surface.
Count U- Number of blob columns around the circumference (1–30). More columns create a denser horizontal arrangement.
Count V- Number of blob rows along the height (1–20). Controls the vertical density of the blob grid.
Width- Blob footprint size relative to cell spacing (0.1–4). At 1.0, each blob just fits its cell. Values above 1 cause neighboring blobs to overlap and merge. Values below 1 create isolated bumps with flat gaps.
V-Shape- Vertical flattening of each blob (0–1). At 0, blobs are circular. At 1, blobs are horizontally stretched into ellipses.
Stagger- 0 = aligned grid (blobs in a straight column). 1 = alternating rows offset by half a cell (brick pattern).
Phase- Phase offset in radians (0–2\u03C0). Rotates the blob pattern around the circumference.
How It Works
The surface is divided into a grid of cells defined by Count U and Count V. Each cell contains one blob centered at the cell midpoint. The blob shape is computed using a smooth falloff function (cosine-based) that creates a peak at the center and drops to zero at the cell boundary.
The Width parameter scales the falloff radius relative to the cell size — wider blobs overlap into adjacent cells, merging into each other for a continuous, bubbly surface. The Stagger parameter shifts every other row by half a cell width, transforming the grid from a rectangular to a hexagonal-like brick layout.
