How to obtain normal, and texture for multi-view reconstruction #26

Hi! Amazing paper, and very clean code! Thanks so much for releasing this.

how to obtain normal map and color map (texture) for multi-view reconstruction ?

m-niemeyer commented 4 years ago

Hi @tharinduk90 !

If you have a trained model (you can use one of the pre-trained models as a start), you can run our generation script to obtain the output. This will produce a mesh which is textured and has normals (both per vertex). In this function we do the per-vertex color prediction, and here we do the normal estimation. If you want to disable the color prediction, you can do this in your config file modifying the generation - with_normals argument. We do not support any other output format of the normals / texture currently.

I hope this helps. Good luck!
