R3DS Wrap

Wrap changes the way you process 3D-scan data.

When working with a large set of similar objects like human scans Wrap makes it possible to take an existing basemesh and non-rigidly fit it to each and every scan.

Wrap also provides a set of very useful scan processing tools like decimation, mesh filtering, texture projection, and much more. Thanks to node-graph architecture once you’ve processed a single scan you can apply the same recipe to an unlimited number of other scans.

What’s new in R3DS Wrap 2021.11

R3DS Wrap 2021.11 is packed with 9 new nodes and a lot of useful features. The new Fast Wrapping node works up to 20 times faster than a regular wrapping. The Point Detector node allows you to automatically detect facial markers on FACS scans.

What Wrap is Used for?

Digital Characters

Wrap lets you convert a series of 3D scans of actors to production-ready characters sharing the same topology and texture coordinates

Scan-Based Blendshapes

Given a series of 3D scans of an actor’s facial expression, generate a set of morph-targets for further animation with Wrap.

Auto rigging

Wrap a known topology around a full-body scan,  a starting point to many auto rigging tools.

Virtual Try-On

Widely used by virtual fitting room vendors. Fitting a body model with a known topology makes it easy to adjust its shape or take measurements and a perform cloth simulation.


License Server

License Server allows users to run floating licenses for R3DS products.

Wrap3 licenses available:

  • Node-locked – a license type that is bound to a specific computer.
  • Floating licenses – allow switching between computers. For example, use it for cases when Wrap should be available for a group of artists, but only occasionally, so they can run it on their computers without the need to purchase Wrap for every computer. In addition, the License Server manages floating licenses. To explain, it handles requests of Wrap instances for available seats and keeps track of their usage.

More Info

Linux

  • RPM – package for RHEL, CentOS, Fedora and other rpm-based distros. The package was built and tested on CentOS 7 and expected to work on all versions above.
  • DEB – package for Debian, Ubuntu and other deb-based distros. The package was built and tested on Ubuntu 16.04 and as well expected to work on all versions above.

Wrap 3.3.11

Released 24 November 2017

New Nodes

IconOpticalFlowWrapping OpticalFlowWrapping
Uses optical flow to fit a textured basemesh to a textured scan. The node can be used to fit a neutral mesh of an actor’s face to 3D scans of his facial expressions. It renders pairs of images of both models from different angles and finds optical flow between the images. For each image pair it generates a set of decisions on where to more each pixel. All the decisions are then combined into a global solution.
IconBlendshapes Blendshapes
Blends input geometry according to blendshape weights. Along with geometric blending the node also provides a real-time preview of texture blending.
Transform Transform
Adds a new transformation to a current transformation of an input geometry. Supports interactive transformation in the 3D-viewport.

Functionality

  • Fast Ray-TracerTexture projection and geometry projection works much faster even for meshes with big triangles. Point selection works with small-scale models.
  • 35 Facial BlendshapesWrap’s gallery now incudes 35 anatomically correct blendshapes. The blendshapes were captured from real person and then transered to a generic face. Thanks to Alexey Bodatirev for careful post-processing of each blendshape.
  • 6 Facial ScansA set of facial scans have been included into Wrap’s gallery.

Bug Fixes

  • LoadGeom node crashes when polygon indices refers to non-existing polygons.
  • Wrapping node crashes when plugging non-geometrical data into the first input.
  • Ray tracing fails for models in small scale. The problem arose for point and polygon selections, ProjectGeom node and TransferTexture node.
  • OBJ-files with polygroups exported from Houdini cause crash on loading.
  • In SelectPolygons node a 100K polygons limit is removed for loop selection. Now loop selection works for any meshes except for ones that contain only triangles.
  • RepairGeom node crashes when input geometry contains invalid polygons and doesn’t have texture coordinates.

Wrap 3.2.0

Released 5 December 2016

New Nodes

Replace
Takes two models in the same topology and seamlessly replaces a part of one model with a part of the other.
 Subset
Detaches a selected part of a model to a separate geometry (a subset). The subset can further be modified, saved, loaded, wrapped or transformed. Any changes in vertex positions of the detached geometry can be later brought back to the original model using ApplySubset node.
IconApplySubset ApplySubset
Works in pair with a Subset node. Copies vertex positions of the subset back to original mesh. The topology and the vertex order of the subset geometry should not be modified.

Functionality

  • Command Line Interface

    Wrap can be run through a command line interface. Find more about command line arguments here.

  • Fullbody Basemesh
    The basemesh was designed specifically for wrapping purposes by Alexey Bogatyrev. It can be used for commercial purposes.
  • MTL Reference Preservation

    Wrap preserves reference to .mtl file when loading and saving model to OBJ-file.

  • Auto-compute is off by Default

    Auto-compute option of Wrapping node is off by default.

Bug Fixes

  • Wrap freezes if the basemesh contains isolated vertices.
  • Parameters of some node reset to default after removing them and undoing remove operation.
  • RepairGeom node does not remove isolated vertices if the input geometry is manifold and does not contain invalid polygons.

Wrap 3.1.0

Released 17 October 2016

New Nodes

IconSymmetry FixSymmetry
Converts a non-symmetrical model to a symmetrical one by changing its vertex coordinates. The input mesh is assumed to have a symmetrical topology.

Functionality

  • Camera to World Axis Alignment

    Click S key in a 3D-viewport to align camera rotation to the nearest world axes. Lets you quickly align the camera to Front, Left, Right, Top, Bottom and Back views.

Bug Fixes

  • SelectPointPairs: clicking on a model to set a point sometimes missed the proper polygon and set the point behind it.
  • Fit to View with LoadGeom node being selected caused to crash if there were no geometry loaded.
  • SubdivideGeom: the node didn’t preserve materials.
  • RigidAlignment: the node ignored transformation of the left input.
  • Clicking Tab or Delete while connecting nodes caused to crash.
  • Wheel zoom was reversed (comparing to Maya) in 3D-viewport.

Wrap 3.0.3

Released 5 September 2016
<

Functionality

  • Node-Graph Workflow
    Wrap 3 is the first step toward node-graph based scan processing. By creating and connecting nodes it allows you to define a recipe of how a scan should be processed and later apply the recipe to dozens of new scans.
  • Project saving

    Projects can now be saved to .wrap file. Internally the file has JSON text format. The structure of the file is simple enough so that one can easily edit node parameters, create and connect nodes using text editor or Python script. That provides access to basic automation.

  • Undo/Redo

    Undo/redo system allows undoing of most operations using Ctrl+Z and Ctrl+Y.

  • Enhanced Wrapping Algorithm
    The wrapping algorithm is much faster and much more robust now.
  • Viewports Synchronization
    When using SelectPointPairs node the left and right views can now be synchronized to speed up selection processing.
  • Enhanced Points Editor
    While working with SelectPointPairs node editor one can click and drag a point and adjust its position. Any point can be removed with Ctrl + LMB.
  • Enhanced Polygons EditorWhen working with SelectPolygons node editor the following new operations are supported:
    • double click selects a set of connected polygons
    • Shift + LMB or lasso selection adds new polygons to selection
    • Ctrl + LMB or lasso selection removes polygons from selection
    • Shift + double click near selected polygons will create a loop selection (only for manifold geometry)
    • +Polygroup/-Polygroup button adds/removes selection from polygroup
    • +Material/-Material button adds/removes selection from material
  • Node Graph Editor
    • Click Tab to show the list of all the nodes that can be created. To create the node choose one from the list or start typing its name and press Return when the desired node appears in look-up menu.
    • Click on an output then click on an input or vice-versa to connect two nodes.
    • Left-click on connection then Disconnect from context menu to disconnect nodes.
    • Hold down MMB over a node to see node information and errors.
    • Hold a mouse over a node input to see input name and type.
  • Batch ProcessingAt the bottom of Wrap window there is a time line. Every loading node (like LoadGeom or LoadImage) allows to select a sequence of file names. When you switch between the frames of the time line the loading nodes will be recalculated to load new file from the list. Each saving node (like SaveGeom of SaveImage) allows to insert # sign inside an output file name. For example ‘WrappedBasemesh###.obj’. When you click ‘Compute current frame’ Wrap will substitute # signs with the current frame number producing ‘WrappedBasemesh001.obj’ In order to process multiple frames in batch mode create and connect the output of your recipe to saving node then click ‘Compute frame range’ inside the node editor. Each frame is computed in parallel in separate process. If you want to compute multiple saving nodes at a time please use main menu Nodes > Compute All.

Known Issues and Workarounds

  • Texture and Geometry projectionTexture and geometry projection slows down significantly when target geometry contains some huge polygons that overlap big number of small polygons. Such models are often produced by RC. You can remove large polygons beforehand.
  • Small models

    Point selection and some other operations may suffer from loss of precision if a model has very small scale. The default units in Wrap are centimeters. You often face small-scale problem when trying to load scans that were saved in meters. Up-scaling the scan by changing ‘Scale’ parameter of LoadGeom node will take no effect. Up-scale the scan and save it in new units, then load saved file and use it.

  • WrappingThere’s no termination button for wrapping process yet.
