Ogbog's Grog Barrel Generator is a geometry nodes setup that creates 3D barrels based on a curve input. By editing the curve with Bezier controls, twisting, and radius scaling, users can define the exact profile of the barrel. The setup includes customizable parameters for adjusting staves, hoops, heads, rivets, and the bung. A low-poly output toggle is included to assist with baking workflows, and the generator can be repurposed to create abstract cylindrical cage structures.
