What are WRAP, ZWRAP and WRAP4D?

Wrap, Zwrap and Weap4D are incredibly useful programs that are available from a company called Faceform – previously known as R3DS (Russian 3D Scan).

So what are the “wrap” programs for?

Well they’re for “topology transfer” – which means that you can make your human-like 3d model perfectly match an existing human-like 3d model’s polygon layout. So you fit a pre-existing topology (or “base mesh”) onto your own custom 3D scan or sculpt (ie. a custom character you’ve sculpted).

Why would you want to do that? Well, systems like Reallusion characters or MetaHuman characters might require you to give your human models an exact number of polygons and / or an exact ORDER of polygons (ie. so the program knows where the various body parts are). But aside from that, Wrap and ZWrap are very useful if you want to apply things like micro detail maps (for skin textures) onto your custom human model. So companies that make micro detail maps – like TexturingXYZ and 3D Scan Store – use the Wrap programs as part of their suggested pipelines.

So the question then is: what’s the difference between WRAP, ZWRAP and WRAP4D?

Well, Wrap and Zwrap are usually used together.

Wrap is a standalone program that is based on nodes. So you have to be ok with setting up node graphs in order to use it.

ZWrap is a plugin for ZBrush. So that means that the process is much more VISUAL and is easier for many people. 

Both Wrap and Zwrap work in basically the same way.

  • You tell the program what your base mesh is, which is your target topology. So you tell it what your custom mesh is, which is your source mesh.
  • You then choose the type of automatic wrapping it does. The easiest one is called the “fast wrap” method. 
  • Then you help the program by telling it which points on source mesh are the same as the target mesh. For example, the top of the lip. These are also called “point correspondences”, or “point pairs”.
  • You also tell the program how to transfer the texture (the skin color etc) from your source mesh to your target mesh. For example, you might want to exclude parts of the source texture graphic file, if it contains things that aren’t needed.

How do you buy WRAP and ZWRAP?

Wrap and ZWrap are available to buy from FACEFORM.com as a bundle together. And you can get them as either a perpetual license (ie. you own it forever) or as a yearly subscription. 

What about Wrap4D?

So what about Wrap4D? That’s a very different program. It’s for HMC performance processing. What does that mean? Well an HMC is a head mounted camera (two cameras actually, for 3D). So this is all about having an actor wear a helmet, which has a camera that records their face. Wrap4D takes the recordings and tracks it in 3D. You end up with a perfect animated 3D model of the facial performance.
