How Regl customizes the shape of Points? about regl

Hi, @Knell0714! There's not a single answer to your question, and regl (or more generally, webgl) doesn't enforce any choices here. Point primitives work fine up to the maximum permitted size, but beyond that you might need to use two triangles to make a quad (instanced rendering might help here). Points are probably a perfect adequate place to start though. Then for each point, you could either apply a texture directly, or you could use the strategy used in regl-scatter2d and compute an SDF from an SVG or bitmap, see: svg-path-sdf, bitmap-sdf. Then you can just adjust the colors using the SDF value to get the look you want.

I made an example of this strategy here: https://observablehq.com/@rreusser/sdf-points-with-regl
