Inverse Projection and Depth Buffer

[Thaumaturge]

1. Do you have a code example I might use in order to understand?

Have you searched the forum? A quick search seems to turn up a few examples.

2. I understood (from my google search) that I am required to write a shader in order to get the depth buffer (does it right?). Do I need to use the extrude method inside a shader?

No, I think that you can get the depth buffer results without writing a shader. This thread seems to have useful information, and I believe that the “Motion Trails” sample program demonstrates (indirectly, I think) a means of doing this by adding a new rendering texture to an extant graphics output (such as the default Panda window). See this API entry, and the one below it, for more information.
