Geometry Node Editor
The geometry node editor is an editor where you can
modify the geometry of objects by nodes. When you
add a node then a modifier gets added too. Geometry
nodes are tied to this modifier.
Add modifer
Geometry nodes
The editor is divided into several
areas has several tool areas.
1. Pan the view - MMB Middle mouse button
2. Mouse Wheel, Numpad + / -
3. View All - Home
Hotkeys
1. Header
2. Tool Shelf
3. Sidebar

When you grab a node input or output, drag it around,
and release it in the empty space, then you will get a
search menu with the available nodes that fits to this
input or output
Node context menu
When you double right click into the viewport, then you will open a menu. The UV

then you can end editing with this operator.
Link to Viewer
Adds a viewer node to the selected node.
Set Position of the cube
The hiding key is M in the
keyboard to see the changes in
the geometric node
Adding a Subdivided Mesh to set The level of them
Connecting Nodes By Adding Join Geometry
Adding inputs and output
Adding a Math tree for calculating the cube shape
Adding Extrude Mesh
Delet the set postion tree by
ctrl + z so the connection is
not lost
Connection Random
Value to Extrude Mesh
Connection Extrude Mesh to
Mesh to point and interface
By adding a new math “sine” to multiply tree and random value we can change the mesh as we see
