180 degree fov

[posterus]

hello
i need to render an image showing a 180 degree field of view. our client wants to see something similar to what a human would see. i am told that our peripheral vision covers 180 degrees. my attempts so far are severely distorted but maybe there is no way around that. i've never tried to simulate this before...any ideas?
much thanks,

While our Field of view covers 180 field of view, this mainly represented by aspect ratio, not FOV in 3D cameras. Accurately to represent human vision I would use a 45 MM or 50 MM camera and an aspect ratio of 2 to 1, 16 X 9 like HD and Film is done to more accurately represent human vision.
180 FOV in camera is a fish eye, not a human eye

What if his client is a fish? Is anybody doing pan files anymore? I remember a camera that rendered 6 views from the camera and assembled in into a pan file.

I've worked on a project where I needed to do something similar. What I did was create a camera with a 45mm FOV. Then I rendered off 2 or 3 (i don't remember) overlapping shots. I just animated my camera rotating 180 degrees and rendered the 2 or 3 frames it took to complete the rotation, allowing for a little overlap. Then I used Autostitch (Google it) to make a panoramic image.

Make sure you have plenty of extra material in the frame as you will need to crop the stitched image a little.

If you use a standard Max camera, you can use cylindrical camera set to 180 in the VRay render settings under the Camera rollout. this feature has no affect on PhysCams unfortunately.

thanks for the suggestions guys. i'll look into them. they want the object in the center to be in focus and have it slowly get blurry the farther away from the center of the frame. i think what i need is some kind of concentric circle dof effect...but i'm still playing with ways to get that.
best,

You can do the blur in post, do one version of the image clean, one blurred and then use a mask with a soft and large falloff to blend the two together.

There was a Photoshop plugin that did just that: you select what's in focus and further from that focus you are, more blured it becomes. I used it just for one shot 4 years ago. Sorry, I can't remember the name but you chould be able to google it

Good luck

Make a circular gradient in photoshop over your image and use that as the z-depth for 'lens blur' in photoshop.

nice trick!
