Cycles: Add "Edge Length" output to the Geometry node Authored by Lukas Stockner (lukasstockner97) on Feb 27 2016, 10:29 PM.
Details This commit adds an output to the Geometry node that gives the average The output isn't really useful for production shaders, but can be handy Requested by @Ronny G (nutel) on IRC.

Event TimelineComment Actions Generally the functionality seems fine to add, though I wonder if this should be in the geometry node? This is one of those options that people should only use for debugging, and there's already quite a few geometry node outputs. So perhaps it makes sense as part of a new Debug / Analysis node? I would like it to be clear that this is not something you typically use for building shaders. "Parametric" belongs in that category as well I think, so could be moved to the same node. It's possible to think of a few more outputs for such a node, like a random per face color, some more advanced way to analyze over/undertessellation, .., so even if this new node would have few options now I could see more being added in the future. By the way, for measuring stress or deformation it's probably better to do what Blender Internal does, comparing to the undeformed coordinates, although it's nice that you can already do something with this edge length now.
Comment Actions Agree with feedback from Brecht. But side note: Bi does quite bad job for stressmap: it indeed calculates difference with underformed mesh, which makes it totally useless for production files and linked characters, because it is often agreed to move character by moving Master bone. This makes full character to be considered fully deformed, which is rather totally useless. If one will work on stressmaps for Cycles he should totally keep this in mind and address it. | ||||||
