Functional Details

This module resamples a grid at a finer resolution or changes the element type.

input

is the object to be refined. It must have "connections" or "faces."

level

specifies either the level or the type of refinement: an integer specifies the number of levels (in powers of 2) of refinement. New positions and connections are added, and any components that are position or connection dependent are interpolated linearly and placed in the output. For quads and triangles, one level of refinement increases the number of elements by a factor of 4, two levels by a factor of 16, and so on. For cubes and tetrahedra, one level of refinement increases the number of elements by a factor of 8, two levels by a factor of 64, and so on. a string has two values: "tetrahedra" refines cubes to tetrahedra; "triangles" refines quads or faces to triangles.

Components

All components in the input are propagated to the output. The "connections" component is modified.
