This is essentially what UV unwrapping is. Seems like a pretty neat auto-UV layout algo... Are people in the Blender community using this plugin for texturing game assets? Does it work well with high poly models?
- eggy 9y agoIt is, but Pepakura which I mentioned above works out the folds and cuts. Any development of 3D models with facets or low count polygons with paper can be done granted with lots of time. It gets interesting when you work in something with some thickness and stiffness, and you want curvature and not facets. I was tweaking 'unfolding' or 'developing' panels from Rhino models for my kayaks as mentioned in a reply up in this thread. The kayaks were made of 4mm Okume plywood and needed to have curved surfaces. The payoff was watching the 3D surface take shape as you "stiched and glued the seams of the 2D panels.
- santaclaus 9y agoThis seems similar, but somewhat different than UV auto-layout in terms of the restrictions on the map. For this mapping to produce a buildable object, each flattened face must have the same area as the 3D face, and the mapping from 2D to 3D must be globally bijective. In UV-mapping, given a set of artist-specified cuts, I do not think it is always possible to obtain an area-preserving and globally bijective map. Most industrial-strength UV tools also allow artists to rescale and deform certain faces (to make it easier to paint under fine geometry, for example), which would be wouldn't make sense given the end goal of this algorithm.
- thomastjeffery 9y agoThe difference is that all faces are proportional. UV unwrapping is almost always done with fewer edges, so the unwrapped mesh ends up distorted.
- UncleEntity 9y agoBlender has a pretty advanced UV layout algorithm builtin for all your texturing needs. This plugin would probably have problems with n-gons which the UV layout tools handle without too much problem.
- knolan 9y agoI’ve dont something simple but similar to this with UV unwrapping in Blender directly. You can even export the UV map to SVG.
- tinus_hn 9y agoWith UV unwrapping you can stretch the pieces, you may even want that to allow for more detail in the texture for specific areas.
