Modeling

Modeling is the process of creating and shaping three-dimensional objects in digital environments. It includes techniques such as polygonal modeling, NURBS, sculpting and procedural methods to define surface detail, topology and volume. In a 3D & XR context modeling also focuses on optimization: controlling polygon counts, creating clean UVs, baking normals and preparing LODs for real-time performance. Modeling is typically the first stage of an asset pipeline and provides the geometry needed for texturing, rigging, rendering and integration into XR applications.

Imagine creating a game-ready character for an AR application: you start with a blockout to establish proportions and silhouette, then sculpt high-resolution details in software like ZBrush or Blender. Next you perform retopology to produce a render- and real-time-friendly low-poly mesh, unwrap UVs and bake normal and ambient occlusion maps to preserve sculpted detail. Finally you create LOD versions and simple collision meshes so the asset performs well on mobile XR hardware.
