What is Z-depth compositing?

What is Z-depth compositing?

This z-depth compositing feature allows you to place 3D objects further and closer within the field of view of the camera together with an image plane mapped with depth information. Objects that are closer than depth values in the image will appear in front of it.

What is depth matte in after effects?

The Depth Matte effect reads the depth information in a 3D image and slices the image anywhere along the z-axis. For example, you can remove a background in a 3D scene, or you can insert objects into a 3D scene.

How do you add depth to an animation?

Use F11 and F12 to see the changes from a different angle. Increase the aperture on the camera to see the depth of field change. Adjust your focus distance to change what object should be in focus. Keyframe your camera position to change over time and watch the magic happen!

How does Z-depth work?

Z-Depth Pass is a very old technique that is used in the composting of 3D computer graphics. Basically, it lets you render 3D scenes without depth of field blur, and then add depth of field as part of post-processing. Most compositing software has tools to create fake depth of field from Z-Depth Pass.

What is Z-Depth pass?

Z-depth works on a grayscale value range to create a depth of field effect when used. The colors in the pass will range from black to white based upon distance from the camera, with black being in the foreground, closest to the camera, and white in the background, with mid-gray values being in-between.

What is depth matte?

Depth of Field is a wonderful thing. Many 3D programs can render this, but it takes a deathly long time. Most 3D programs allow you to render a depth matte which is basically a black and white image, where white shows things close to the camera and black is far away.

Which blur effect supports the use of a depth matte to define the focal range?

Depth Of Field effect
The Depth Of Field effect simulates a camera that’s focusing at one depth (focal plane) in a 3D scene, blurring objects at other depths. This effect uses the depth information from the auxiliary channel of an imported file representing a 3D scene.

How do I add depth to a vector in after effects?

If you want to add depth to your vector art and text, consider creating it in Illustrator, using the 3D effects, and then importing the results into After Effects. After Effects can import 3D-image files saved in Softimage PIC, RLA, RPF, OpenEXR, and Electric Image EI format.

What are the 3D channel effects in after effects?

See Third-party plug-ins included with After Effects. The 3D Channel effects work on 2D layers—specifically, 2D layers with 3D information in auxiliary channels. The sources of these 2D layers are image sequences that represent 3D scenes that have been rendered out of a 3D application.

What are RGBA channels in after effects?

These 3D-image files contain red, green, blue, and alpha (RGBA) channels, as well as auxiliary channels with optional information, such as z depth, object IDs, texture coordinates, and more. Though you can import composited files with 3D information into After Effects, you cannot modify or create 3D models directly with After Effects.

How does after effects work with VPE files?

After Effects uses the information in the .vpe file to re-create the scene as a composition containing a camera layer and one perspective-corrected 3D layer for each PNG file. The camera is on the negative z axis, at (x,y)= (0,0). The point of interest for the camera is in the center of the composition.
