> Raymarching is costly and rarely used in realtime engines but Blender isn't realtime so rendering SDFs directly would probably be viable. The viewport still

  It's a lot easier to handle realtime in an editor than in a fully featured game. There's less other stuff going on, you can take extra shortcuts and usually rely on higher-end hardware.

    > It's a lot easier to handle realtime in an editor than in a fully featured game. There's less other stuff going on I don't think that's true. Most games are optimized to limit the number of draw calls and textures. The viewport of a 3D software package has no such limits. As a result, my viewport rarely runs as well as the games I play. In any case, that's besides the original point, which was that it wouldn't need to run in realtime. My argument was that it would. It's not a completely impossible goal. Look into what some artists are making with Dreams on the PS4. It uses raymarched SDFs for modeling.

      Point taken. Small correction - Dreams isn't purely Raymarched SDFs. From recollection they ended up with a fairly hybrid approach.

        I haven't read much about it to be honest. I know they must be doing something clever under the hood to make it run so we'll on that hardware.
