Bộ Điều Chỉnh Làm Mịn Laplacian

The Smooth Laplacian modifier allows you to reduce noise on a mesh's surface with minimal changes to its shape.

It can also exaggerate the shape using a negative Factor.

The Smooth Laplacian is useful for objects that have been reconstructed from the real world and contain undesirable noise. It removes noise while still preserving desirable geometry as well as the shape of the original model.

This modifier is based on a curvature flow Laplace Beltrami operator in a diffusion equation.

Gợi ý

Meshes with a great number of vertices, more than ten thousand (10,000), may take several minutes for processing. You can use small portions of the mesh for testing before executing the modifier on the entire model.

Bộ Điều Chỉnh Làm Mịn Laplace -- Laplacian Smooth Modifier.

Lặp Lại

Repetitions allow you to run the smoothing operation multiple times. Each repetition causes the flow curvature of the mesh to be recalculated again, and as a result it removes more noise with every new iteration using a small Factor < 1.0.

When on 0, no smoothing is done.

Ghi chú

More repetitions will take longer to calculate. So beware of doing so on meshes with a large number of vertices.

Hệ số Lambda

Controls the amount of displacement of every vertex along the flow curvature.

  • Using a small Factor, you can remove noise from the shape without affecting desirable geometry.

  • Using a large Factor, you get smoothed versions of the shape at the cost of fine geometry details.

  • Using a negative Factor, you can enhance the shape, preserving desirable geometry.

  • When the Factor is negative, multiple iterations can magnify the noise.

Ranh Giới Lambda

Since there is no way to calculate the curvature flow on border edges, they must be controlled separately. Border edges are smoothed using a much simpler method, using this property to control the influence.

Positive values will smooth the vertex positions, while negative values will "enhance" them by transforming them in the opposite direction.

Inverts the influence of the selected vertex group, meaning that the group now represents vertices that will not be deformed by the modifier.

The setting reverses the weight values of the group.
