3D signed distance function geometry nodes
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
The signed distance function nodes can be used to define complex 3D geometry using simple
|
||
|
|
shapes.
|
||
|
|
|
||
|
|
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 **render** node.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
All output samples shown in this section are preview images.
|
||
|
|
|
||
|
|
All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found
|
||
|
|
`on this page`__.
