Hi Guys
I have some questions to understand the concept of the mesh_camera, maybe you can shed
some light on this:
1) I learned by reading the wiki that each pixel in the resulting image needs one face
in a camera mesh.
Just to ensure that I got it right, does it mean that a mesh like this could be used
to create an image with width 4 and height 2 ?
+----+----+
| 1 /| 3 /| 1 2 3 4
| / | / |
| / | / |
|/ 2 |/ 4 |
+----+----+
| 5 /| 7 /| 5 6 7 8
| / | / |
| / | / |
|/ 6 |/ 8 |
+----+----+
2) can I imagine a mesh_camera as an insects eye?
Each facette representing one ray and its direction looking out to the world in a
slightly different direction?
3) Is it true that I need a mesh of the right dimensions to match exactly the
resolution of my resulting image?
that implies that I had to prepare a different mesh whenever I change the resolution
4) Are there already tools to create plane meshes of given resolution?
Otherwise I had to write a script or Povray Macro to do this.
5) Using faces of a mesh for the mesh_camera seems to be gratuitously complicated to
me.
Why didn't the programmer choose a bunch of vectors, that could also describe the
origin and direction of rays.
Just a quick thought that made me wonder.
I think there must be another reason beside that it can't be called mesh_camera if it
is made using vectors :o
thanks
