about

Compute normals for triangulated surface meshes

ie pairs of vertices/indices sets.

  • Face normals: one normal per face (=triangle) of the mesh
  • Vertex normals: one (smooth) normal per vertex with different weighting options (area, angle,...)
  • Corner normals: one normal per indexed triangle corner

This is basically a wrapper around libigl's(http://libigl.github.io/libigl/) functions to compute normals, more info here:
http://libigl.github.io/libigl/tutorial/tutorial.html#normals

   
   

Installation Note:

Always copy the dependencies folder (+helpfiles) with the plugin!

   
      

Source Code:

The source code for the vvvv plugin as well as for the unmanaged "libigl_Normals.dll" can be found in my addonpack fork:
https://github.com/digitalwannabe/vvvv-sdk/tree/develop/vvvv45/addonpack/src/nodes/plugins/3d/3dComputeNormals

  
   

Licenses:

All my code is MIT where possible; always happy about credit to digitalWannabe/lichterloh
All code from libigl is MPL2

  
    
As this plugin is very useful for meshes generated by tetgen, it will be included in it's next update. As such it will also be part of d.o.p.e., where it can help with shading deformed meshes correctly (-> next update)!
  
NOTE: this plugin is VERY alpha, ie mainly untested, please report your findings!

microdee: @synth: care to make an issue on github with console output?

synth: @microdee cant install DX11 with it, cant choose not to install it either. Cant install anything without disregarding dependensies

joreg: @okvrdz i recommend starting here: topics it should give you a good overview of what's all there

microdee: vpm is updated and DO update as it fixes an issue with new latest DX11 script https://github.com/vvvvpm/vpm/releases/latest

okvrdz: to those experienced v4 users... What in your opinion is the best/easiest way to learn nodes and what they do/usage/capabilities?

bildwerk: @jzzxh its on the todo list :)
