mesh2heightfield

Converts a mesh file into a projected 2D image given from a normal direction N and from a starting point P.

The 3D mesh is discretized and scanned in the normal direction N, starting from P with a step 1.

Usage: mesh2heightfield [input] [output]

Allowed options are:

Positionals:
  1 TEXT:FILE                           input heightfield file (2D image).
  2 TEXT                                output image.
 
Options:
  -h,--help                             Print this help message and exit
  -i,--input TEXT:FILE                  input heightfield file (2D image).
  -d,--domain UINT x 2                  specify the domain (required when normal are imported and if --inout is not given).
  -o,--output TEXT                      output image.
  --importNormal TEXT                   import normals from file.
  --orderedNormalsImport                Use ordered normals.
  --lightDir,--lDir,--ld FLOAT x 3      light source direction: lx ly lz.
  --lightPos,--lPos,--lp FLOAT x 3      light source position: px py pz.
  -s,--specularModel FLOAT x 3          use specular Nayar model with 3 param Kdiff, Kspec, sigma.
  -r,--reflectanceMap TEXT:FILE         specify a image as reflectance map.
  --hsvShading                          use shading with HSV shading (given from the normal vector)
  --normalMap                           generates normal map.
  -v,--invertNormals                    invert normal orientations.

Example:

$ mesh2heightfield -i ${DGtal}/examples/samples/tref.off  heighfield.pgm

You will obtain such image:

Resulting heightfield.
