# calculate-volume-map¶

## Synopsis¶

calculate-volume-map <input> <output> [options]


## Description¶

This tool computes a mapping for each point of the volume of a given input point set. The input is either a piecewise linear complex (PLC), i.e., a tesselation of the surface, or a tesselation of the shape’s volume such as a tetrahedral mesh generated from a PLC. The output is a volumetric map which assigns points of the volume one or more values. The volumetric map can in general interpolate any values given on the surface of the map domain at the interior of the volume. More common use cases are to compute a bijective map from one volumetric shape to another with identical topology. The resulting map is a re-parameterization of the volume of the input shape. Such parameterization can be used for texturing, object deformation (cf. “cage deformation”), object morphing, and surface- constraint image registration.

## Arguments¶

input

Boundary surface mesh or volumetric mesh.

output

File path of output map. A piecewise linear map is stored as VTK file. Other maps are stored in a custom binary format.

## Output options¶

-acap

As-conformal-as-possible volumetric map.

-harmonic

Harmonic volumetric map.

-meshless

Use meshless mapping method if possible.

## Standard options¶

-v, -verbose [n]

Increase/Set verbosity of output messages. (default: 0)

-debug [level]

Increase/Set debug level for output of intermediate results. (default: 0)

-version [major.minor]

Print version and exit or set version to emulate.

-revision

Print revision (or version) number only and exit.

-h, -help

Print help and exit.

## Terminal options¶

-color, -nocolor

Enable/disable colored output. (default: off)

## Parallelization options¶

-threads <n>

Use maximal <n> threads for parallel execution. (default: automatic)
