Problems about Camera position optimization using differentiable rendering #224

I 'm working on Windows 10 and I 'm trying the example of Camera position optimization using differentiable rendering. I use phong_renderer to render the object and the background is white but I notice that your pictures have a black background. Can you tell me how to change the background? Thanks a lot!

We have added support of a variety of background colors defined in BlendParams

This allows you to specify the color of the background.
