Functionality

Wrap 3.3.11

Released 24 November 2017

New Nodes

 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.

 Blendshapes

Blends input geometry according to blendshape weights. Along with geometric blending the node also provides a real-time preview of texture blending.

 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

• 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.
