problem about running the UI interface #2

I find that in edit_widget.py, there are some functions about shadow, and I also check the paper ShadowDraw. My problem is, is the Data Generation step necessary? Is it for building a shadow dataset to guide the users? Can you provide thoes images or I have to build it myself? Many thanks!

It is not necessary.

  1. You can ignore related codes about shadow. Without it, it may be a little difficult to draw the correct sketch consistent with the viewpoint.
  2. You can randomly select some samples from the dataset to generate the shadow, as I do. I generate the dataset via the scripts under tools/sketch_rendering/. Here I have provided same samples in sketch_transparent_20.zip.
  3. You can use some fixed samples to generate the shadow.

Thanks for your reply, it works now and hope that I can make some contributions based on your method.
