Blender has a [[Node graph architecture|node graph system]] for [[Procedural generation|procedurally]] and non-destructively creating and manipulating geometry. It was first added to Blender 2.92, which focuses on object scattering and instancing.<ref>{{cite web|title=Blender 2.92 Release Notes|url=https://www.blender.org/download/releases/2-92/|url-status=live|website=blender.org|archive-url=https://web.archive.org/web/20210225175316/https://www.blender.org/download/releases/2-92/|archive-date=2021-02-25}}</ref> It takes the form of a modifier, so it can be stacked over other different modifiers.<ref>{{cite web|title=Geometry Nodes Modifier — Blender Manual|url=https://docs.blender.org/manual/en/2.93/modeling/modifiers/generate/geometry_nodes.html|access-date=2021-10-08|website=docs.blender.org}}</ref> The system uses object attributes, which can be modified and overridden with string inputs. Attributes can include [[Position (geometry)|positions]], [[Normal (geometry)|normals]] and [[UV mapping|UV maps]].<ref>{{cite web|title=Attributes — Blender Manual|url=https://docs.blender.org/manual/en/2.93/modeling/geometry_nodes/attributes_reference.html|access-date=2021-10-08|website=docs.blender.org}}</ref> All attributes can be viewed in an attribute spreadsheet editor.<ref>{{cite web|title=Spreadsheet — Blender Manual|url=https://docs.blender.org/manual/en/2.93/editors/spreadsheet.html|access-date=2021-10-08|website=docs.blender.org}}</ref> The Geometry Nodes utility also has the capability of creating primitive meshes.<ref>{{cite web|title=Mesh Primitive Nodes — Blender Manual|url=https://docs.blender.org/manual/en/2.93/modeling/geometry_nodes/mesh_primitives/index.html|access-date=2021-10-08|website=docs.blender.org}}</ref> In Blender 3.0, support for creating and modifying curves objects was added to Geometry Nodes;<ref name=":7">{{cite web |last=Foundation |first=Blender |title=Procedural Curves in 3.0 and Beyond |url=https://code.blender.org/2021/09/procedural-curves-in-3-0-and-beyond/ |access-date=2021-09-27 |website=Blender Developers Blog |date=16 September 2021 |language=en}}</ref> in the same release, the Geometry Nodes workflow was completely redesigned with fields, in order to make the system more intuitive and work like shader nodes.<ref name=":8">{{cite web |last=Foundation |first=Blender |title=Attributes and Fields |url=https://code.blender.org/2021/08/attributes-and-fields/ |access-date=2021-10-02 |website=Blender Developers Blog |date=17 August 2021 |language=en}}</ref><ref name=":9">Archived at [https://ghostarchive.org/varchive/youtube/20211211/Yci5ouEmnLI Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20211002130722/https://www.youtube.com/watch?v=Yci5ouEmnLI Wayback Machine]{{cbignore}}: {{Citation|title=Geometry Nodes Fields: Explained!| date=30 September 2021 |url=https://www.youtube.com/watch?v=Yci5ouEmnLI|language=en|access-date=2021-10-02}}{{cbignore}}</ref>
