I have just released a new addon called Logo Tracer. It automatically generates a Mesh or Curve object from a simple image. No external SVG files required!
This can be super useful if you are given a logo from a client who wishes to see it in 3D or if you want to convert an existing shape from an image to a curve / mesh like a neon sign!
I’ve tried your addon against some b/w ornament alphas and your addon doesn’t seem to work well for them. Perhaps, it’s my settings but I’ve tried a bunch of different combos. Leafig addon seems to be giving you some serious competition there.
It adds a subdivided plane using the given image as displacement
Then a second plane is used with a boolean option to slice a sample from this displacement
The problem here is that the subdivided plane (when set to high) only goes up to 4 subdivisions and with incredibly detailed imagery there isn’t enough vertices available to sample the image correctly. Therefore you would need to select the hidden displacement object after generation and increase the subdivisions further to the desired amount. That being said this will have huge impacts on performance so I would keep that in mind.
Regarding Leafig giving me “serious competition”, this is a paid addon for 15 EUR ($17.50 USD) and Logo Tracer is 100% Free. I would hope Leafig does a better job, otherwise you are paying for nothing.
This functionality is very specific and would cause problems when used in a generic way like Logo Tracer is intended to be used.
Here I would suggest using an image editor to break up the different color components and feed each color separately through logo tracer before doing a boolean union on all the resulting meshes
