Tutorial 15: question about projection

[Maia R.]

Dear community,

I am working on https://scalismo.org/docs/tutorials/tutorial15 and I tried to apply with dense point correspondence for model fitting similar to https://scalismo.org/docs/tutorials/tutorial11.

I was wondering if it is possible (and how) to apply projection such as in parametric, non-rigid registration (https://scalismo.org/docs/tutorials/tutorial12) for non-rigid icp-based registration (shape+pose):

=======

val registrationTransformation = transformationSpace.transformationForParameters(registrationResult.parameters)

val fittedMesh = referenceMesh.transform(registrationTransformation)

val targetMeshOperations = targetMesh.operations

val projection = (pt: Point[_3D]) => {

targetMeshOperations.closestPointOnSurface(pt).point

}

val finalTransformation = registrationTransformation.andThen(projection)

val projectedMesh = referenceMesh.transform(finalTransformation)

val resultGroup = ui.createGroup("result")

val projectionView = ui.show(resultGroup, projectedMesh, "projection")

======

or ICP-based techniques should not use such a projection ?

Thank you,

Best regards
