Nice. I would still need a basic tutorial about what happen (from an
external user's point of view).
For instance, take a scene.pov; With normal 3.7RC3, the command line
would be "foo bar zorglub scene.pov" (well probably something more like
"povray -Iscene.pov -H480 -W640 +A0.01 +FN")
The output would be a png file, named scene.png.
With your patched version, if I want the depth map, what is the command
line ? If I do not want the depth map, can I expect using the 3.7RC3
command line with the new binary or do I need something else ?
How is named the depth map file ?
What is its format ? How can I see it (I would like to be impressed like
a lambda Mac/Iphone/Ipad user: no internal techniques, just nice pictures) ?
Is the camera position & setting output in another file (what is its
name ?) or is that part of the depth map file ?
I'm sure the people dealing with depth map on a daily basis all know
this stuff, but so far the poor neophytes are just left on the side of
the road without a clue.
