动态拓扑

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.

• Detail Type

• Dyntopo uses three different detail methods to create dynamic detail to an object.

  • Relative Detail
  • This method uses a detail size based on the number of pixels, and in turnwill create topology in that size. Zoom out big details, zoom in small fine details.
  • Constant Detail
  • To keep detail uniform across the entire object, Constant Detail can be used.The Detail is based on the percentage of a single unit.
  • Brush Detail
  • Giving more control over the topology, with this method you can create topologybased on the brush size. You can increase and lower topology by simply resizingthe brush itself. The detail size is based the size of the brush itself, where100% will create topology the size of the brush ring itself.
• Detail Size/Percentage, Resolution Shift-D
• Detail Refine Method
• • Subdivide Edges
  • Just like the Subdivide tool, this method will only subdivide topologyto match the detail given.
  • Collapse Edges
  • When topology is too dense, and is smaller than the detail given, edges willbe collapsed to fit the detail size appropriately.
  • Subdivide Collapse
• Smooth Shading
• Toggles whether mesh faces are smooth or flat-shaded.In dynamic-topology mode all faces have the same type of shading.
• Optimize
• If sculpting begins to slow down while dynamic topology is enabled,use the Optimize button to recalculate the sculpt BVH.
• Detail Flood Fill
• When using Constant Detail mode, this option is made available, allowingyou to fill the entire object with a uniform detail, based on the detail size.
• Direction
• Determines which direction the model will be symmetrized.
• Symmetrize
