#N-Way Blender Two or more shapes are being blended according to the user specified weights. Weights can be specified numerically or using the included Weight Controller plugin based on the generalised barycentric weight.
#Reference For the detail of the algorithm, refer to the paper
- S.Kaji, "Tetrisation of triangular meshes and its application in shape blending", Mathematical Progress in Expressive Image Synthesis III, pp. 7--19, Springer-Japan, 2016. DOI: 10.1007/978-981-10-1076-7, http://arxiv.org/abs/1601.04816
#How to compile:
- Get devkit at https://www.autodesk.com/developmaya
- MacOS: look at the included Xcode project file ( or Makefile )
- Windows: look at the included Visual Studio project file. DO NOT turn on AVX instructions.
- on some systems, specifying the compiler option -DEIGEN_DONT_VECTORIZE may be necessary to avoid compilation errors (thank giordi91 for this information)
#How to use:
- Place the plugin files in "MAYA_PLUG_IN_PATH" (*.mll for windows, *.bundle for mac)
- Place the UI python script files in "MAYA_SCRIPT_PATH" (ui_*.py)
- Open Script editor in Maya and type in the following Python command:
import ui_nwayBlender as ui
ui.UI_NwayBlender()
import ui_weightController
ui_weightController.UI_WeightController()First, create an N-Way blender deformer by selecting (shift+click) target shapes and clicking "create" in the UI menu. The last shape will be deformed. Optionally, create a weight controller node by selecting control points and clicking "create" in the UI. Then, connect output of the controller to the input of N-Way blender by clicking "Out2Nway." Now the target shape is deformed by moving the controller object around. Look at the included jpg and video files for details.
To visualise ARAP energy, go to "Display" => "Polygon" => "Custom Polygon Display" and tick "color" and select type "emission."
#LIMITATION The ARAP version works only on "clean" meshes. First apply "Cleanup" from "Mesh" menu to remove zero area faces and zero length edges.
