Signed Distance Fields in the Visual Effect Graph
Typically when we create a texture we think of it as a grid of numbers, each of which represents a ‘brightness’. 0 is black, 1 is white. Coloured textures simply extend this concept to store 3 values (or 4 if transparency is included). Whilst typical textures are very useful for general purpose imagery, they are not particularly … See more Before proceeding, another aspect of shaders and textures needs a mention – texture sampling. Thus far in the above examples we’ve been using a 16×16 … See more Ok! Armed with a distance field, and a GPU that utilises bilinear filtering to smoothly sample the pixels of that field, lets see what we can build. Our first and simplest … See more WebNov 10, 2024 · The simplest signed distance field function is the one for a circle. The function will only take a sample position and a radius of the circle.
