<h1>3D signed distance function geometry nodes<a class="headerlink" href="#d-signed-distance-function-geometry-nodes" title="Permalink to this headline">¶</a></h1>
|
|
<p>The signed distance function nodes can be used to define complex 3D geometry using simple
|
|
shapes.</p>
|
|
<p>They are based on a very small set of basic shapes, that can be combined using operators,
|
|
and finally output as a greyscale heightmap and a color normal map using the <strong>render</strong> node.</p>
|
|
<p>Describing 3D objects using SDF primitives is more difficult than using existing meshes, but this
|
|
method integrates smoothly with shader generation, and (as many nodes in Material Maker) is
|
|
resolution independant.</p>
|
|
<p>All shapes can be associated to a color index that can be used to apply different (2D or 3D) textures
|
|
to the result.</p>
|
|
<p>All output samples shown in this section are preview images.</p>
|
|
<p>All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found
|
|
