Origins

Functionality

The node produces centers, normals, tangents for any element of given mesh. Also it can combine the data into matrix. The output is close how blender is placing moving axis of selected mesh element in normal mode.

Category

analyzers -> origins

Inputs

• Vertices - vertices

• Edges - edges (optionally)

• Faces - faces (optionally)

Outputs

• Origin - center of element, in vertex mode just coordinates of current vertex

• Normal - normal of current element

• Tangent - tangent to current element

• Matrix - built from origin, normal and tangent data matrix

Parameters

Parameters	Type	Description
Element mode	enum	Vertex, edge or face
Flat matrixes list	bool	Put matrixes of each input object into one list (N-panel)
