[R&D] The Tools for a curve-based modeling techniques in Houdini
2020 was for me a year of research and development in the field of surface modeling. Here are the tools (still in development) for creating a relief surface from curves and for applying relief to existing surfaces.
The wrinkles created using the deformer curves, that was drawn on surface. (Old test, now working on more advanced, profile-based deformers)
Just a test for a "teeth inserting". The curves, extracted after boolean subtraction are used then as deformers to thicken the edges of the gums.
The two rails sweep, looks simple and logical. But it needs a appropriate parameterization of the both rail curves in a cases when they are of different length, curvature and even have singularity (like the inner one in this example).
Wireframe of previous. The "singular point" can be seen in the center of the spiral.
The blade was modeled using a slightly different variant of a two-rail sweep, that supports 3d mesh instead of profile curve. The blade relief with fuller first created on the simple straight mesh and then "swiped" along curved rails.
