Generating and saving a mesh

[Masa Stanisavljevic]

I want to generate a mesh from the Basel Face Model and save it in a .ply file, so that I can use another rendering engine to render a face image based on the mesh. Can this be done with the code available in this repo? If so, how would one go about this? Thank you in advance!

Sure - in few lines of code:

import java.io.File

import scalismo.faces.io.{MeshIO, MoMoIO}
import scalismo.utils.Random

object RenderMesh extends App {
  scalismo.initialize()
  val seed = 1986L
  implicit val rnd = Random(seed)
  
  val model = MoMoIO.read(new File("/path/to/baselFaceModel.h5")).get
  val instance = model.sample()
  MeshIO.write(instance, new File("/out/path/mesh.ply"))
}

If you are not interested in lots of model instances you might also just use our model-viewer GUI?

Its a simple java executable and you can write out a ply-file

Hi, 

Thank you for your prompt response. I used the model-viewer GUI to generate a few meshes. However, the .ply documents do not contain information about the colors of the faces. How can I save those as well? 

Thank you

[Bernhard Egger]

They should?

It writes vertex colored meshes and you can visualize them using meshlab
