However, the technique can still be performed though in a slightly awkward way.</p> <figure class="node-visual"> <img hr-src="https://docs.radiant-pixel.com/radiantsdf/images/techniques/nodeGraph_ScaleSpace.avif" src="https://docs.radiant-pixel.com/radiantsdf/images/techniques/nodeGraph_ScaleSpace_prev.avif" alt="Scale Space Node Graph Simple" width="100%"> </figure> <p>In order for the scaling to work correctly, one needs to:</p> <ol> <li>Divide the space by the desired Scale</li> <li>Calculate the signed distance field function that needs to be scale using the divided space</li> <li>Multiply the resulting signed distance field by the scale to keep the distance values correct</li> </ol> <p>In order to do this for more complex shapes, I recommend to use named reroute nodes, this keeps the process a lot more tidy.</p>
