Re: SDF. what do you think of it?
okidokiThanks for interesting links but still sounds like a toy not very relevant to actual game art production. Same as Metaballs. Rather an interesting toy. I am for example still waiting when Designer would get any convenient manual touching/finishing tools or otherwize Painter get something like node based level of a… -
Re: SDF. what do you think of it?
@gnoop, it just occurred to me that you've been using them for years in designer, it just doesn't mention it Using max() blend mode to combine heightmaps is exactly the same as using min() on a pair of SDFs that represent the same surfaces. (Invert and rerange to -1:1 to get the SDF) It's mathematically more convenient to… -
Re: SDF. what do you think of it?
One has to distinguish: Signed distance fields or functions does define some volume. Ray Marching is one possible algorithm to compute SDF's. Another possibility are voxels.. even if "rastered". One may say that the (original) metaballs are a very simple version of SDF.. only some radius around some ball centers… -
Re: SDF. what do you think of it?
SDFs are used in many different ways like making reading text in games less pixelated. https://www.youtube.com/watch?v=CGZRHJvJYIg 2D wise it can also be used for example in creating rain hitting the floor, creating a raindrop effect, 3D wise, intersections to visualize visibility shapes, ranges... or like a less resource…
