Bộ Điều Chỉnh Phân Rã (Decimate Modifier)

The Decimate modifier allows you to reduce the vertex/face count of a mesh with minimal shape changes.

This is not usually used on meshes which have been created by modeling carefully and economically (where all vertices and faces are necessary to correctly define the shape). But if the mesh is the result of complex modeling, sculpting and/or applied Subdivision Surface/ Multiresolution modifiers, the Decimate one can be used to reduce the polygon count for a performance increase, or simply remove unnecessary vertices and edges.

Unlike the majority of existing modifiers, this one does not allow you to visualize your changes in Edit Mode.

The modifier displays the number of remaining faces as a result of the Decimate modifier.

Tùy Chọn (Options)

Thu Gọn (Collapse)

The Decimate modifier in Collapse mode.

Merges vertices together progressively, taking the shape of the mesh into account.

Tỷ Số (Ratio)

The ratio of faces to keep after decimation.

• On 1.0: the mesh is unchanged.

• On 0.5: edges have been collapsed such that half the number of faces remain (see note below).

• On 0.0: all faces have been removed.

Ghi chú

Although the Ratio is directly proportional to the number of remaining faces, triangles are used when calculating the ratio.

This means that if your mesh contains quads or other polygons, the number of remaining faces will be larger than expected, because those will remain unchanged if their edges are not collapsed.

This is only true if the Triangulate option is disabled.

Đối Xứng (Symmetry)

Maintains symmetry on a single axis.

Tam Giác Hóa (Triangulate)

Keeps any resulting triangulated geometry from the decimation process.

Vertex Group (Nhóm Điểm Đỉnh)

A vertex group that controls what parts of the mesh are decimated.

Hệ Số (Factor)

The amount of influence the Vertex Group has on the decimation.

Phi Phân Hóa (Un-Subdivide)

The Decimate modifier in Un-Subdivide mode.

It can be thought of as the reverse of subdivide. It attempts to remove edges that were the result of a subdivide operation. It is intended for meshes with a mainly grid-based topology (without giving uneven geometry). If additional editing has been done after the subdivide operation, the results may be unexpected.

Số Lần Lặp Lại (Iterations)

The number of times to perform the un-subdivide operation. Two iterations is the same as one subdivide operation, so you will usually want to use even numbers.

Mặt Phẳng (Planar)

The Decimate modifier in Planar mode.

It reduces details on forms comprised of mainly flat surfaces.

Giới Hạn Góc (Angle Limit)

Dissolve geometry which form angles (between surfaces) higher than this setting.

Phân Giới (Delimit)

Prevent dissolving geometry in certain places.

Normal (Pháp tuyến)

Does not dissolve edges on the borders of areas where the face normals are reversed.

Nguyên Vật Liệu (Material)

Does not dissolve edges on the borders of where different materials are assigned.

Đường Khâu (Seam)

Does not dissolve edges marked as seams.

Sắc Nhọn/Đột Ngột (Sharp)

Does not dissolve edges marked as sharp.

UVs

Does not dissolve edges that are part of a UV map.

Toàn Bộ Ranh Giới (All Boundaries)

When enabled, all vertices along the boundaries of faces are dissolved. This can give better results when using a high Angle Limit.
