A stone model created using geometric nodes is a three-dimensional object consisting of many geometric shapes (for example, cubes, spheres, etc.) combined into a single structure. This approach allows you to create complex objects using simple shapes and operations on them. One of the features of the model is the ability to change its dimensions. To do this, you can use special tools that allow you to scale an object in all three dimensions. You can also change the shape of the stone using operations on meshes and other geometric primitives. In addition, the stone model can be customized with different textures, allowing you to create stones of different colors and shades. Thus, a stone model created using geometry nodes is a flexible and customizable object that can be used in various 3D projects.
