WebSep 24, 2024 · I am looking for advice on how to render fonts really sharp. And on the other hand also how to get a really pixelated look for fonts matching really old and pixelated games (the font should then look very crisp and pixelated too regardless the resolution). So these are maybe two different goals: a) Really sharp “HD” font WebGenerating the signed distance fields is pretty slow even on a fast machine so you really ought to do it in an offline step.

WebDec 28, 2024 · A Signed Distance Field is a mathematical construct where the distance to a closed surface is computed along a set of positions, with the sign of the distance used to indicate whether the position is inside or outside the surface. The positions are typically chosen to be on a regular grid and they work well in both 2D and 3D. They were made …
WebIn a signed distance field, the value of each pixel is how far that pixel is from the edge of the shape you've selected. Negative distances mean the pixel is inside the shape, positive distances mean the pixel is outside the shape. Zero means the pixel is exactly on the shape. The output of an SDF shape is Texture2D_1ch, as the shape outputs ...
