2D Signed distance function geometry nodes
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The signed distance function nodes can be used to define complex 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 image using the **sdShow** node.
|
|
|
|
All output samples shown in this sections are images generated through the **sdShow** node.
|
|
|
|
All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found
|
|
`on this page`__.
