Modeling: Improved Edge Loop Editing

This task involves various enhancements, such as: "Clone" Support for Edge Slide: An option for the Edge Slide tool which, when enabled, duplicates the corresponding edges first and then slides them. See RCS#2rcbbc, RCS#QDbbbc. Edge Flow: Adjusts the edge loop via spline interpolation such that it respects the flow of the surrounding geometry. See RCS#vddbbc. Loop Cut Curvature Preservation: Option added to loop cutting that when enabled places loop vertices on the curvature of the surrounding geometry with spline interpolation rather than with flat linear interpolation. See RCS#fSdbbc Expected outcomes: Additional loop-editing operators available in edit-mode. Skills required: Proficient in C++, Linear Algebra. Possible mentors: Campbell Barton, Tariq Sulley Expected project size: 350 hours Difficulty: hard
