Did you know that it is possible to generate Z-Depth in Ae from After Effects layers? Chris Zwar shows us how with the next logical step, using only native features.
You can create Z-Depth maps in After Effects by using the approach described here. Creating and compositing with z depth textures through Trapcode Particular, you are able to easily achieve what you need!
While After Effects can’t automatically generate its own z-depth maps (at least not in 2014), we have the ability to use a similar technique that I demonstrated back when this particular tutorial was first published. Once you find an effect composition and it’s right for what you’re going after, duplicate your layer(s) under a new name so one will only contain depth information instead of both color data as well.
All a depth pass really does is capture an image that correlates to distance. If you’re in front of a scene with black fog and white objects, the ones on top will be darker than those lower down because they’ve been captured by photography long before us!
In the past, before 3D applications had dedicated Z-Depth rendering tools for deaths passes, we would use a process called “death pass” which involved animating an object over time.
In some films or video games you may have seen this type of effect on display: it’s when one thing propels another away from them at different speeds until it becomes invisible in midair – just like how light cuts through fog without being stopped! The term comes from motion pictures’ early days where photographers needed special equipment to capture these types shots accurately during filming sessions by using handheld cameras—hence why they’re also known as “long camera motions.”
Here, Chris shows something similar by creating Z-depth from After Effects layers. He measures the distance of each individual layer to his/her camera and converts that data into shades using an easy fill effect!
