How does the fisheye projection model work?
This is my first contact with the fisheye model/lens type and I'm trying to understand how it works.
I put some sphere on a circle at different angles 0(red), 30(vert), 60(blue), 90(jaune), 120(mag …

Camera setting does not give the expected fisheye result
I am modeling a real camera with a wide angle (fisheye). My room is 4*4*2.5 meters and the camera is attached in the ceiling with {0,0,0} degrees rotations. … For camera setting, I added a camera named prosilica having a sensor type 2/3" (8.8mm*6.6mm). as mentioned in the image 1 and 2.
When I render the scene, i remark:
1) It does not a distortion effect! …

Configuration of Cycles fisheye camera
I try to use the cycles fisheye lens:
with a 2/3" sensor type
camera is attached in the ceiling at 2.5m in a room
focal length is 2.2mm
filed of view is 180 degrees.
sensor size (2/3") is 8.8mm * 6.6mm … However, when I chose a large sensor, the image plane of a camera is contracted and when I chose small sensor, the image plane of a camera is extended (image2). …
