What does Z Depth do?

A depth buffer, also known as a z-buffer, is a type of data buffer used in computer graphics to represent depth information of objects in 3D space from a particular perspective. Depth buffers are an aid to rendering a scene to ensure that the correct polygons properly occlude other polygons.

What is a depth buffer OpenGL?

The depth buffer is automatically created by the windowing system and stores its depth values as 16 , 24 or 32 bit floats. In most systems you’ll see a depth buffer with a precision of 24 bits. When depth testing is enabled, OpenGL tests the depth value of a fragment against the content of the depth buffer.

What is depth value?

Depth is a measure of the distance from a viewing position to a specific pixel. When using depth testing, you add a depth texture (sometimes called a depth buffer) to your render pass. A depth texture stores a depth value for each pixel in the same way that a color texture holds a color value.

How do I render a depth pass in C4D?

Cameron shows how to set up C4D to render a depth pass using C4D’s multi-pass system. Then in After Effects using Cineware and Zblur (a sapphire plugin) to apply the DOF effect. You can then adjust the focal length right in After Effects without a worry.

Can I create a depth of field post effect in after effects?

Motion Science shows how to create a depth of field post effect in After Effects to renders coming out of C4D. One thing that is notoriously a long render time in 3D is a depth of field effect. It’s no wonder that most opt to render a post effect so that you can apply a DOF effect in After Effects.

What is motionmotion Science’s depth of field post effect?

Motion Science shows how to create a depth of field post effect in After Effects to renders coming out of C4D. One thing that is notoriously a long render time in 3D is a depth of field effect.
