Hi itk-developers,
I’m using the itkDeformableSimplexMesh3DFilter to make a local adjustment of a simplex mesh. I was inserting a gradient image in the deform filter, however I want to insert a texture image instead of a gradiente image. I’m reading the mesh from a vtk file and the imagem from a NIfTI file. Do you have any suggestions how can I do this? Let me know if you need any further information, please.
Every help or idea is helpful.
Thank you,
Leonardo.

As [DeformableSimplexMesh3DFilter](https://itk.org/Doxygen/html/classitk_1_1DeformableSimplexMesh3DFilter.html) only works with gradient images, you will need to convert your texture image into a gradient image. I assume you are not after a [simple gradient](https://itk.org/ITKExamples/src/Filtering/ImageGradient/ComputeGradientMagnitude/Documentation.html), so conversion from a texture to a gradient should be problem-dependent.
