SDF Editor

SDF Editor is a simple editor for creating procedural signed distance fields.

How it works

The procedural SDF is evaluated for an arbitrary point in space by first transforming the point as specified by the scene tree. This includes translations, rotations, mirroring but also repetition or elongination. This is done top to bottom until a primitive is reached, so the distance to that primitive can be evaluated at the transformed point. After the distances to all transformed primitives are calculated, they can be combined as given by the scene tree. This is where operators like e.g.  subtraction or thickening are applied.

This produces a signed distance field that can be raymarched. The emitted shader code for the SDF is visible in the editor.

It's a prototype

This is a proof of concept since I don't know if such an editor really is useful. It has the needed functionality for editing and saving / loading SDFs. Some missing features are:

• Copy / Paste and Duplicating objects
• Undo / Redo
• Materials (at least solid coloring of objects)
• Voxelizing for export and editing in other programs
• More render / camera options + shader export

The amount of time I will invest in working on this editor depends on your interest, so leave a comment (suggestions for additional features are welcome) if you think this editor deserves continued development!
