MULDIFA is an addon for Blender (2.83+) which implements a distance field. It adds the ability to create a field within a scene, and allows one to interact with it. One can set which objects influence and sample from the distance field, as well as this, MULDIFA is multi-layered, meaning that one can control which influencing objects affect which sampling objects, allowing for isolation. Sampling is primarily done in the form of baking to a png texture, though there is also an option for writing to vertex colours or groups.
Notice:
It should be stated that this addon is not a rendering engine, and does not contain any distance field rendering functionality. The field is also not signed (there is no distinction made between the inside and outside of a mesh). The addon also only supports use within a single scene (I've not tested it in a multi-scene setup, so it may work depending on the use case, though I can't give any guarantees).
On top of this, I must state that the creation of this addon was first and foremost a learning exercise in programming. This is the first non-trivial software project I've attempted and so it may contain some bugs though I will attempt to fix any that are brought to my attention.
Platforms:
MULDIFA supports use on 64bit versions of Windows, Linux, and MacOS. (I've not yet tested the addon on an ARM platform (such as M1 MacOS), so I cannot guarantee that it will work on these systems).
