Depth comes in two varieties, (sorry i'll use ue3 terms dunno what proper ones are) Pixel Depth is the distance from the camera to the pixel on the object. Scene depth is the distance from the camera to the pixel on the scene either in front of the object or behind it. With pixel depth you can make the object change color…
The zdepth is 1 value, and 1 value only. Any kind of concept that UE3 throws at you as the end user saying it's different things isn't technically correct under the hood. You can get the depth with either per-vertex or per-pixel precision (like basically everything). You're right kodde, it's just a distance relative to the…
Hmm... this is new to me so not familiar with all these concepts, yet. What I have at the moment is ray distance, I'm using this as the "Pixel Depth" term you described. Shift color or whatever. Trying to comprehend what you meant with Scene depth. So lets say I have a sphere inside a box like room. The camera is inside…
I'm referring to Depth from a definable Near Plane/Far Plane. Explain what you mean by both. Scene would be depth to farthest point being rendered? And "depth of pixel" from nearest to farthest within one object?
