WebMesh sizes are defined as relative to the starting background mesh. For example, if the background mesh size is 0.2 m, the mesh sizes at one and two levels of refinement will be 0.1 m and 0.05 m respectively. Note refinement is performed by cutting cells in half in each direction, i.e. a 3-D cell is transformed into 8 cells. Castellation parameters WebApr 12, 2024 · Dynamic topology (aka dyntopo) is a dynamic tessellation sculpting method, adds and removes details on-the-fly, whereas regular sculpting only affects the shape of a mesh. This makes it possible to sculpt complex shapes out of a simple mesh, rather than just adding details onto a modeled base mesh. Dyntopo can be toggled with the … shard 1WebUsage.
