# What is 3d in Nuke?

## What is 3d in Nuke?

Nuke’s 3D workspace allows you to set up a 3D composite for camera moves, set replacement, and other applications where you need to simulate a “real” dimensional environment.

What is a node in Nuke?

Nodes are essentially small mathematic machines. You put your input through them (with its given channels red, green, blue, alpha, and many more in some cases) and it manipulates these pixels in some way. The Foundry’s reference guide is a library of nodes and one of your most valuable resources when learning Nuke.

How many nodes does Nuke have?

With over 200 creative nodes, Nuke delivers everything you need to tackle the diverse challenges of digital compositing. This includes industry-standard keyers, rotoscope, vector paint tools, color correction and so much more.

### How do you create a mesh in Nuke?

Click Bake Selected Groups to Mesh. A mesh is created automatically using the information from the PointCloudGenerator node. Note: You can use the resulting group mesh node in Nuke as well, though you can’t edit the geometry. Proceed with Adding Texture to a Mesh.

What is point cloud Nuke?

Using the PointCloudGenerator node (NukeX and Nuke Studio only) you can create a dense point cloud based on the information generated by CameraTracker and use the dense point cloud further to create 3D meshes of your 2D footage. Note: The analysis must be performed in NukeX, but the result can be used in Nuke.

What is B pipeline Nuke?

The merge node intuitively lends itself to a structure that follows a B pipeline: one stream of merge B connections from your plate to your viewer. This structure keeps your graph organized and allows you to disable and enable parts of your composition through your merge nodes alone.

## What is Premult in Nuke?

The simple definition of premult is to multiply the alpha and the RGB of the input together.

Is Nuke better than after effects?

From the outside it seems like both After Effects and Nuke produce similar results, and while this is for the most part true, the node-based workflow of Nuke can make compositing much easier, especially if you are working with 3D elements.
