public sealed class MeshSimplifier
The MeshSimplifier type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | MeshSimplifier | Creates a new mesh simplifier. |
Properties| Name | Description | |
|---|---|---|
 | Agressiveness |
Gets or sets the agressiveness of the mesh simplification. Higher number equals higher quality, but more expensive to run.
Default value: 7.0
Obsolete |
| BlendShapeCount | Gets the count of blend shapes. |
| BoneWeights | Gets or sets the vertex bone weights. |
| Colors | Gets or sets the vertex colors. |
| EnableSmartLink |
Gets or sets if a feature for smarter vertex linking should be enabled, reducing artifacts in the
decimated result at the cost of a slightly more expensive initialization by treating vertices at
the same position as the same vertex while separating the attributes.
Default value: true
Obsolete |
| MaxIterationCount |
Gets or sets the maximum iteration count. Higher number is more expensive but can bring you closer to your target quality.
Sometimes a lower maximum count might be desired in order to lower the performance cost.
Default value: 100
Obsolete |
| Normals | Gets or sets the vertex normals. |
| PreserveBorderEdges |
Gets or sets if the border edges should be preserved.
Default value: false
Obsolete |
| PreserveSurfaceCurvature |
Gets or sets if the discrete curvature of the mesh surface be taken into account during simplification.
Default value: false
Obsolete |
| PreserveUVFoldoverEdges |
Gets or sets if the UV foldover edges should be preserved.
Default value: false
Obsolete |
| PreserveUVSeamEdges |
Gets or sets if the UV seam edges should be preserved.
Default value: false
Obsolete |
| SimplificationOptions | Gets or sets all of the simplification options as a single block. Default value: SimplificationOptions.Default |
| SubMeshCount | Gets the count of sub-meshes. |
| Tangents | Gets or sets the vertex tangents. |
| UV1 | Gets or sets the vertex 2D UV set 1. |
| UV2 | Gets or sets the vertex 2D UV set 2. |
| UV3 | Gets or sets the vertex 2D UV set 3. |
| UV4 | Gets or sets the vertex 2D UV set 4. |
| UV5 | Gets or sets the vertex 2D UV set 5. |
| UV6 | Gets or sets the vertex 2D UV set 6. |
| UV7 | Gets or sets the vertex 2D UV set 7. |
| UV8 | Gets or sets the vertex 2D UV set 8. |
| Verbose | Gets or sets if verbose information should be printed to the console. Default value: false |
| VertexLinkDistance |
Gets or sets the maximum distance between two vertices in order to link them.
Note that this value is only used if EnableSmartLink is true.
Obsolete |
| VertexLinkDistanceSqr |
Gets or sets the maximum squared distance between two vertices in order to link them.
Note that this value is only used if EnableSmartLink is true.
Default value: double.Epsilon
Obsolete |
| Vertices | Gets or sets the vertex positions. |
