UV

UV mapping is a technique used to “wrap” a 2D image texture onto a 3D mesh.

Trandiational method (rendering algorithm)

• automatically-generating-uv-coordinates-algorithms
• tri-planar mapping

• Neural network method

• NN
  • Neural 3D Mesh Renderer
• GAN
  • UV-GAN: Adversarial Facial UV Map Completion for Pose-invariant FaceRecognition

Pros and cons

• Trandiational
  • The traditional method is to divide the face into different areas and map them separately.
    • The advantage is that the materials of different areas can be changed separately
    • divide manually.
      
• NN
  • Use NN generate uv texture directly
    • no need to divide the area manually.
    • difficult to control the texture of different areas of the face separately

Meeting

• create docker image for convenience
• sorted vertices
• join Blendshape as group
• weight for different expression
  • For similar expressions, how to determine the weight of each blendshape?
• [] different face lead to no solution
  • is there a way to make two models have the same number of faces?

next week will focus on surface mapping texture to 3d face model and fix resolution problems.
