Title: ZBuffer Clamp
Post by: postwendend on 2013-12-24, 12:21:46

The option to use an unclamped zbuffer would be great.

for example.

i use a min of 0.0cm and a max of 100.0 cm as setting for my zbuffer
a pixel in my image has the value 1.0f at 1m distance between this particular point and the camera. so you would be able to check your camera distance using the zbuffer.

if the zbuffer clamped the values clipped by 1.0f

Unclamped zbuffer is a great thing for sure, but not for checking camera distance. There are simpler ways to check it.

But for post processing it's great. In photoshop you may choose one distance for blur, another for air perspective,saturation, fog and so on just by using exposure. It would be really great.

And in this case you don't need min and max distance at all.

a simpler way for checking camera distance in post ? how ? i thought this was the only "way"

Just I can't imagine situation, when I need to measure it in the post. But still it's good idea I think.

ok, the output is now unclamped. I've also removed world Z depth render element, as it can be now easily simulated with the other one
