Module Description

The module generates a Body Centric Cubic (BCC) mesh from a labeled image. Initially the generated mesh is homogeneous, that means does not distinguish different tissues. Later the module specifies which tissue each tetrahedron belongs to. Each tissue is capable of automatically adjusting its resolution based on its geometric complexity and the predefined subdivision criterion. The current version of the module supports a single-tissue input labeled image.

Use Cases

Panels and their use

Mesh Generation Parameters: Size: Controls the size of the mesh. The smaller the value the larger the mesh. Value should be between [1,20] (default: 8). Fidelity: Controls the subdivision of the elements that belong to more than one image labels. The larger the value the better the conformity of the mesh on the image label boundaries. Value should be between [0.1,1] (default: 0.8). Resample Resolution: Controls the image resampling. Suggested value is 0 (no-resampling) for large tissues and 1 or 2 for smaller tissues. Value should be 0 or 1 or 2 (default: 0). Input/Output: Input Labeled Image: The input labeled image. Output Mesh File: The output tetrahedral mesh in vtk file format. (default: outputMesh.vtk)

User Interface

Note: this module will only work if the input image has identity orientation!
