Hi everyone,
Here is my progress in the Google Summer of Code project:

   - Tasks done this week:
   - Reading the tessellation code used to generate triangles of building
      from polygons
      - Experimented with the Qt3DExtras::QDiffuseMapMaterial and explored
      some alternatives. Unfortunately some of the alternatives are
not available
      in the Qt version I use (Qt5.9).
      - Tried compiling QGIS with different Qt versions.
      - Added texture coordinates to the vertex buffer of
      - Got the basic functionality of texturing buildings using 1 texture
      image working for some vector layer projects.
      You can see the texture rendering in action here: screenshot
   - Tasks to be done:
   - Refine how the user chooses textures and include a default texture in
      case anything goes wrong with the texture image.
      - Define a generic class that handles material definition in a way
      that it can be extended for physics based rendering and other types
      of materials in the future.
      - Currently there are 4 types of vector layer data and some of them
      are not working properly so I will make the texturng work for
them as well.
      - Make a way to rotate texture coordinates using an angle specified
      by the user.
      - Discuss how we define separate roof textures from walls textures.

You can find the report here as well: wiki page
I am open to any suggestions and feedback.
Best wishes,
