Great tutorial! It clears up a lot of my questions about various effects.

Minor complaint: Focal length is size of the lens. Focal distance is the distance between the camera and the focal point.

Currently is not possible to drop a file or group of files (or folders) from the desktop to a Panda3d window. In my case, as I am doing a media player/file sequence flipbook, it would be a great feature. Don't know if it would be useful for a game, but any kind of application that uses P3D as the backend would have a benefit of it.

Loading a BAM file does not automatically add BulletBodyNodes to a BulletWorld. This step needs to be done manually after loading a BAM file. The docs should describe how to do this.

Ideally this would work whether the model is using CollisionSolids or Bullet shapes.

The Windows screenshots in the introductory section look dated, because they were made with Windows 7, and Panda3D 1.8. We should redo them on Windows 10.

The PBR shader assumes that it can ready texture data as linear data (i.e., that an sRGB texture format is used and the hardware is doing an sRGB to linear conversion). The tonemapping shader also does a linear to sRGB conversion. Models imported via panda3d-gltf already use an sRGB format. However, other models will not use sRGB formats by default and can look weird (washed out or too dark). Th

It would be helpful if there were a readme file that contained information about how to install cefpanda, and contained some basic documentation or links to the example code.
