Module: Refine Surface ()

Description:

This is an experimental module from the Xtra Library: https://xtras.amira-avizo.com.

This module refines a surface by replacing qualified triangles with 4 smaller triangles.

A triangle gets qualified for refinement if its shortest edge length is superior to a user-defined minimum length and if its longest edge length is superior to a user-defined maximum length.

The algorithm iterates on all triangles until no more triangles are qualified for refinement or until a maximum user-defined number of iterations is reached.

Note: Unlike other approaches this algorithm does not smooth edges because the replacing triangles inherit their orientation from their parent's triangle.

Limitations: This module is only available on Microsoft Windows platforms

Connections:

Data [required]
Surface to be refined.

Ports:

Edge Length

Use this port to set the minimum edge lengths to qualify a triangle for refinement. A triangle gets qualified if its shortest edge length is superior to a user-defined minimum length and if its longest edge length is superior to a user-defined maximum length.

Max. Iterations

Use this port to set the maximum number of iterations. If the maximum number of iterations is reached and even if there are still triangles that qualify for refinement, the algorithm is terminated.
