Let's say I have some image that I'd like to somehow make into a 3D model. What I'd like to do is to convert each "blob" from the image into a solid object so that I can view the geometry from any angle I want, assign materials to the solids, and render for some nice visuals.
I've attached a small part of one of the images below that you can use to try
I tried following this type of a workflow:
- Use threshold in Photoshop on the image to clean it up a bit, but I don't want to lose all the side "blobs". So don't set the threshold too low.
- Import to Illustrator and "trace image" to get it to vector format. Play around with the advanced options to get a good number of edges while keeping relatively smooth lines.
- Export from Illustrator as an AutoCAD drawing.
- Extrude all the created objects in AutoCAD to a small thickness, so that each blob has some "body" to it.
- Assign a material to the solids and render using desired settings.
The problem is after exporting as an AutoCAD drawing, there are many splines and hatches in AutoCAD. Some of them are not joined, some of them have overlapping sides, etc. It becomes extremely difficult to extrude efficiently. Since the actual image is much larger, I cannot individually fix every edge.
Are there any other more efficient methods or workflows for doing this? Or any suggestions for handling a large number overlapping hatches/splines in AutoCAD?
