3D model enhancement

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium communicatively coupled to the processor, wherein the processor is configured for executing instructions stored in the non-transitory computer-readable medium to perform operations comprising:
• receiving a fine mesh as input, the fine mesh representing a 3-Dimensional (3D) model and comprising a first plurality of fine-mesh polygons, a second plurality of fine-mesh polygons, and a third plurality of fine-mesh polygons,
• grouping the first plurality of fine-mesh polygons, the second plurality of fine-mesh polygons, and the third plurality of fine-mesh polygons into a first near-planar region of a coarse mesh and a second near-planar region of the coarse mesh, the first near-planar region comprising a first coarse-mesh polygon corresponding to the first plurality of fine-mesh polygons, the second near-planar region comprising a second coarse-mesh polygon corresponding to the second plurality of fine-mesh polygons and a third coarse-mesh polygon corresponding to the third plurality of fine-mesh polygons,
• applying a deformation to the coarse mesh, wherein applying the deformation the coarse mesh comprises:
• increasing an angle between the first coarse-mesh polygon and the second coarse-mesh polygon based on the first coarse-mesh polygon being in the first near-planar region and the second coarse-mesh polygon being in the second near-planar region, and
• decreasing an angle between the second coarse-mesh polygon and the third coarse-mesh polygon based on the second coarse-mesh polygon and the third coarse-mesh polygon being in the second near-planar region, and
• transforming the deformation into a modification for the fine mesh, and
• applying the modification to at least some of the first plurality of fine-mesh polygons, at least some of the second plurality of fine-mesh polygons, and at least some of the third plurality of fine-mesh polygons.
