Get Objects Data

Functionality

Get objects from the Blender Scene and output them into Sverchok’s node tree. This node supports most object types. All are converted to a Sverchok representation of Mesh where possible.

A few points worth stating explicitly.

• Empties, Cameras, and Lamps produce only matrix data.

• The order of the selected Objects can be sorted by name.

• It supports Object collections.

• It understands also vertex groups, when activated, showing additional socket representing indices, that you can use for further processing. All groups are cached in one list _without_weights_.

• When you Get objects from the Scene that have modifiers on them, you can import the final mesh by enabling the Post button.

• Importing Objects with a lot of geometry will decrease Sverchok tree update speed, be careful with any modifiers that produce a lot of extra geometry (like subdivision modifier)

• The Matrix socket lets you ignore or acquire the Object’s World Matrix, by default the Object data is untransformed. Use a matrix-apply node if you want to explicitly transform the vertex data.

limitations:

• When you use the Post mode Sverchok/Blender expect Objects to be visible. If you want to “hide” the original Objects in the scene to avoid visual clutter, you can place them into a Collection and hide the collection. This is a current Blender API limitation.

• We have Bezier-in and NURBS-in nodes if you want to get Curve data from Scene objects, instead of Mesh.

Inputs

Objects Socket

Parameters

Param	Type	Description
G E T	Button	Button to get selected objects from scene.
sorting	Bool, toggle	Sorting inserted objects by name
post	Bool, toggle	Postprocessing, if activated, modifiers applied to mesh before importing
vert groups	Bool, toggle	Import all vertex groups that in object’s data. just import indexes

3D panel

The node can show its properties on 3D panel. For this parameter to 3d should be enabled, output should be linked. After that you can press scan for props button on 3D panel for showing the node properties on 3D panel.

Outputs

Output	Description
Vertices	Vertices of objects
Edges	Edges of objects
Polygons	Polygons of objects
Vertex Normals	Vertex Normals
Material Idx	Material indexes per object face.
Polygons Areas	Polygons of objects.
Polygons Centers	Polygons Center of objects.
Polygons Normal	Polygons Normal of objects.
Matrix	Matrices of objects
Vers grouped	Vertex groups’ indices from all vertex groups

It can output Numpy arrays of vertices and edges if enabled on N-panel properties (makes node faster)

Examples

Importing an object with two array modifiers applied and showing indices.
