Surface Inflation

This is a definition for creating inflated or bulging surfaces. It works on both trimmed and untrimmed surfaces, and can for example be used together with a hex-script to create ETFE-panels.

The definition first untrims the surface and creates a uv-grid of points. The points within a specified radius from the centre are then moved along the surface normal, in proportion to their distance to the surface midpoint. The modified points are weaved together with the unaffected points and fed into a surface from points-component, which created a new bulging surface. Lastly, this surface is trimmed according to the input surface and the definition is complete.

Two examples of the definition used together with a planar honeycomb pattern and a grid of surface frames:
