Decimar

O modificador do tipo Decimar permite que você reduza a contagem de vértices ou faces de uma malha com mínimas alterações de formato.

Isto não é comumente usado em malhas as quais foram criadas por uma modelagem cuidadosa e de maneira econômica (onde todos os vértices e faces são necessários para definir corretamente o formato do modelo). Mas caso a malha seja resultante de uma modelagem complexa em conjunto com escultura e / ou modificadores de subdivisão de superfície ou multirresolução, o modificador do tipo decimar pode ser usado para a redução da contagem de polígonos para uma melhoria na performance (da porta de visão) ou para simplesmente remover vértices e arestas desnecessários.

The Decimate Modifier is a quick and easy way of reducing the polygon count of a mesh non-destructively. This modifier demonstrates the advantages of a mesh modifier system because it shows how an operation which is normally permanent and destroys original mesh data, can be done interactively and safely using a modifier.

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

O modificador Decimar.

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

Proporção (Taxa)

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.

Nota

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, the number of remaining faces will be larger than expected, because quads remain unchanged if their edges are not collapsed.

This is only true if the Triangulate option is disabled.

Grupo de vértices

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

Fator
The amount of influence the Vertex Group has on the decimation.
Triangular
Keeps any resulting triangulated geometry from the decimation process.
Simetrizar
Maintains symmetry on a single axis.

(De-)Subdividir

../../../_images/modeling_modifiers_generate_decimate_panel-un-subdivide.png

O modificador Decimar.

Can be thought of as the reverse of subdivide. Attempts to remove edges that were the result of a subdivide operation. 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.

Interações
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.

Plainar

../../../_images/modeling_modifiers_generate_decimate_panel-planar.png

O modificador Decimar.

Reduces detail on forms comprised of mainly flat surfaces.

Limite angular
Dissolve geometry which form angles lower than this setting.
Todas as margens
When enabled, all vertices along the boundaries of faces are dissolved. This can give nicer results when using a high Angle Limit.
Delimitar

Prevent dissolving geometry in certain places.

Normais
Does not dissolve edges on the borders of areas where the face normals are reversed.
Materiais
Does not dissolve edges on the borders of where different materials are assigned.
Costuras
Does not dissolve edges marked as seams.
