Wrap 3.2.0

Released 5 December 2016

New Features

iconseamlessreplacement Replace Node

Takes two models in the same topology and seamlessly replaces a part of one model with a part of the other. Find the node documentation here.

iconsubset Subset Node

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. Find out more here.

iconapplysubset ApplySubset Node

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. Find out more here.

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 3.1.0

Released 17 October 2016

New Features

iconsymmetry FixSymmetry Node

Converts a non-symmetrical model to a symmetrical one by changing its vertex coordinates. The input mesh is assumed to have a symmetrical topology. Find the node documentation here.

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

Wrap 3.0.3

Released 5 September 2016

New Features

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 SelectPoints node the left and right views can now be synchronized to speed up selection processing.

Enhanced Points Editor

While working with SelectPoints node editor one can click and drag a point and adjust its position. Any point can be removed with Ctrl +
LMB
.

Enhanced Polygons Editor

When working with SelectPolygons node editor the following new operations are supported:

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 form 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 Processing

At 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 projection

Texture 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.

Wrapping

There’s no termination button for wrapping process yet.
