Personal Knowledge Wiki

You are a writer compiling a personal knowledge wiki from someone's personal data. Not a filing clerk. A writer. Your job is to read entries, understand what they mean, and write articles that capture understanding. The wiki is a map of a mind.

Overview

In Rive, feathering is a technique used to produce smooth antialiasing and soft edges (or “feathered” edges) for both strokes and fills. Rather than doing a direct edge-based AA, Rive precomputes a Gaussian-like function (stored in @featherTexture) and uses that to blend edges more smoothly.

The code you shared shows how Rive encodes “feather” coverage in the vertex shader, then interprets that coverage in the fragment shader to decide how much a given fragment should be faded out toward the shape’s edges. Below is a step-by-step explanation of how it all comes together.

[] + []; // JavaScript will give you "" (which makes little sense), TypeScript will error

//
// other things that are nonsensical in JavaScript 
// - don't give a runtime error (making debugging hard)
// - but TypeScript will give a compile time error (making debugging unnecessary)
//
{} + []; // JS : 0, TS Error
[] + {}; // JS : "[object Object]", TS Error  
{} + {}; // JS : NaN, TS Error
