[Addon] UV-driven mesh flattener

IPv6 · July 28, 2017, 4:28am

Flattening of deformed/curved mesh can be tricky, so this operator can help a little.
It is using active UVMap and “applies” it to selected faces, flattening it in more controllable manner.

It can be helpful if you need to preserve face distirbution during flattening or perform “limited bending” toward flat presentation of your mesh, utilizing Blender power to generate and edit such unwrapped presentation

Some screens to show-off the idea:

UV map using “Follow active quad”

Flattening, driven by this UVMap. Here it is 100% flattened, but you can set any other percentage (to get limited bending that follow mesh curvature)

Operator use last selected vertex as “anchor”, flattening will happen around its position in UVMap

# Operators:
# - Cut long edges / Subdivide big faces into smaller one
# - Select all visible vertices/Deselect visible/invisible verts. Can give "strange" results in local mode, since raytrace using WHOLE scene ALWAYS!
# - Flatten inner vertices (of selected region) on the virtually-visible convex-hull of region boundaries
# - Bridge edges of selected mesh regions based on min distance between vertices

I’ve tried out the UVmap operator and it was exactly what I looking for. Thanks very much for sharing!
