Fish Eye in Cinema 4d

Some years ago I found myself in need to simulate a rendering generated in the optical photograph of a double angle type Fish-Eye. Cinema 4d by default does not provide this function, although there are numerous settings on which we are going to go into action. Here's how ...
In photography, the objectives Fish-Eye (literally: eye of fish) are wide-angle lens that captures an image hemispheric very vasta.La main characteristic is their wide-angle lenses of short focal length, usually below 35mm for 35mm or diagonal of the frame into other formats. These features mean that the image took a distortion in which forms are enlarged toward the center of the room and they become smaller hand we depart from this.

I posted this tutorial on forum C4dZone.com anyway here is the summary!

We need only two elements to achieve the effect, of a material and of course an object to be rendered to see the result.

Then import into our room a scene with Target, a ball and arrange so that the ball is just in front of goal but without penetrating it.

Now place the ball inside the hierarchy of the room, so we hooked our Fish-Eye! Whatever the coordinates of the target ball will follow our move.

Create a new material which we call "Fish-Eye-Material" and attribuiamolo the House. Let the default values for colors, disable and enable the Mirror Transparency. At this point we can only work at will on the values of refraction and that's it!

Decimal attention because small changes produce huge results. To begin, download the package Fish-Eye Camera and start rendering!
